Climate Change – call for a united front

Published

on

“Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath”-Nathaniel H. Egleston

At the turn of the 20th century, amidst the deteriorating environmental conditions, Nathaniel Egleston –the second Chief of the US Division of Forestry – took to his guilty conscience, awakened by a then-murky threat to existence that loomed large and heavy, and took his woes to the public eye. Through his renowned article for the Harper’s magazine, titled “what we owe the trees”, Egleston expressed his concerns about the influence of the then-pioneering Industrial Revolution on both the landscape and demography. He saw what others could not – capitalism at the expense of survival, veiled in the guise of a better way of living. While humans marveled at the leaps and bound it made, the ‘almighty dollar’ took helm and Mother Nature took the fall. Trees gained superficial economic value, and lumber production became common parlance – money was rolling in the pockets like never before, and the dollar assumed divinity. People took and took whatever they wanted from mother nature without holding their end of the bargain – there was no give-and-take; just take. People had adopted what Egleston pointed out as a “freebooter style”, and he could see what everything was leading up to – humanity at a crossroads with nature. Reforestation was then alien a concept, and there was no sight of karmic justice. Nature did come to settle the bargain once or twice, but it did not awake the human conscience on a global scale. The infamous smog of 1952 capitalized on the remorse of industrialists, but after a series of repeated denials of the correlation between the deaths and the pollution that the coal stations emitted, prompted the British government to reconsider its energy mix and pass the world’s first “Clean Air Act”. But that was it for the rest of the world then, for money had to be made fast and economies had to be built. Profiteering became humanity’s best friend at the expense of the trees – our sincerest compadres. Common wisdom dictates that the value of something is not realized until it is gone, and the same applies to mother nature – trees slowly exacted its vengeance, and the world we lived in changed for the worse. We won the battle but slowly started losing the war without even knowing about it; or how Egleston subtly says:

“The trees are man’s best friends; but man has treated them as his enemies. The history of our race may be said to be the history of warfare upon the tree world. But while man has seemed to be the victor, his victories have brought upon him inevitable disasters”

Humans are creatures of habit – where threats to survival loom in, the conscience breaks free and humanity is pushed to a united front. Lands, weapons and bombs may have reigned supreme for a while, but no more – there’s a new kid on the block, and he is as ruthless and merciless as one can be. Even the monster under the bed falls pale in comparison to the nightmare of our own creation. Climate change – or perhaps more aptly, climate ‘breakdown’ – is the greatest challenge facing humanity in the twenty-first century.2020 bears witness to it – was the world not warned earlier about the impacts of messing with the environment, one of them being an outbreak of zoonotic vector-borne disease? Were red flags not raised on every medium possible (with even Netflix featuring an explanatory episode in its popular infotainment show, “Explained”, on the looming risks of the pandemic)?  Were they not raised high enough? Did we not hold our end of the bargain with nature? It is ironic for the very species that relies on the trees – for the oxygen to breathe in, for the fruits it bears for energy, for the by-products it expels for the profiteering we wag our tails around, and for regulating extreme temperatures that we face (to name a few) – to take it for granted. Did trees change course? No, but humans did. Egleston would be turning in his grave right about now.

So, what has exactly brought humanity to crossroads with nature? What has brought the need to fight for our survival? And the most important questions that one need to ask is: why is unanimity of support a forlorn dream? Why is climate modification not treated as an existential threat in various modicums of the social order? Rational questions with irrational directives, one must say.

“Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time”

(IPCC)

The proof is truly in the pudding. People have started to notice. Glaciers have shrunk; ice caps on water bodies are breaking apart; water body levels are rising and getting warmer; temperature and weather patterns are exhibiting volatile aberrations; species are changing trajectories; the flora and fauna around are slowly counting its days; trees are flowering sooner than expected; agricultural yields are shrinking; water cycles are accelerated in an unhealthy discourse for its inhabitants; coral reefs are bleaching; marine and terrestrial ecosystems are on the brink of destruction; and the list goes on. By 2018, mean warming of about 1.2°C beyond preindustrial baseline has already caused unacceptable impacts, but it does not stop there. The demons are coming sooner than one predicted – as per WMO’s estimates, the mean increase of 1.5°C, expected by 2030, will be here earlier than expected (no more than in the following five years). There’s more – through 2024, nearly every region on Earth is predicted to be hotter than it has been in the “recent past”. The Arctic region will experience the most significant warming by then – it has already witnessed its ‘historic’ loss in ice caps in the year 2020. The Antarctic region will experience the most significant storms by then – something it does not usually bid hello to. Forget horror movies and folklores for the thrills and chills; we’ve set a stage for all the horrors to follow. The climate change models, unlike most models of differing purposes, have remained mostly accurate. The pandora’s box is slowly unravelling, and the wake-up call has never sounded more desperate than now.

“As climate model projections have matured, more signals have emerged from the noise of natural variability that allow for retrospective evaluation of other aspects of climate models — for instance, in Arctic sea ice and ocean heat content. But it’s the temperature trends that people still tend to focus on.”

(Gavin Schmidt)

It is true that temperatures and weather patterns are changing. But what does it mean for the survival of human life, exactly? Well, the more the world stockpiles on greenhouse gases in the atmosphere, the more we risk the depletion of the protective stratospheric ozone layer – 2020 bears witness to the historic deficit in ozone layer over the Antarctic region. The deficit that, in the preceding year, exhibited the lowest historic contraction ever has left everyone in a flurry of negative emotions, and that too in a year where anything and everything could happen. More harmful ultraviolet radiations (the B- and C- types) are able to easily penetrate all protective layers that the atmosphere harbors. This is where greenhouse gases add insult to injury –if any heat was meant to escape, the entrapment of carbon dioxide and nitrogen oxides, to name a few, will ensure that the lid remains tight. In effect, heat waves become common practice. More people are affected and pushed to the gallows with increasing prevalence of heat cramps and strokes. Rates of melanoma and cataracts cases keep jumping with every day we choose to turn a blind eye to mother nature. Children are resultantly born with genetic mutations. When the human body’s core temperature reaches the temperature of 38.5°C, an adult is exposed to a cascade of symptoms, and healthy organ functioning is, in due process, compromised. Living a healthy life has become a difficult and often dangerous task to fulfill.

“Climate change is not just an environmental issue; it is a technology, water, food, energy, [and] population issue. None of this happens in a vacuum”

(David W. Titley)

It takes on a toll on the produce that we eat and the water we drink to surviveon. With trees maturing faster than disposed, the fruits they bear do not necessarily possess the nutrients it ought to carry – in extreme cases, they bear no fruits at all. For the capitalist and profiteers, another perspective might run a chill down the spine: crop yields are falling. Forget biofuels if the crops are not enough to even feed a single person. For the consumers, it equates to undernutrition and malnutrition. Climate modifications will alter the trajectory of migration patterns of harmful insects and pests – the locust infestation (and the economic and social losses it carried with it) should come as no surprise at all for the inhabitants of Kenya, Somalia and some South-East Asian nations (Pakistan included). With an already-domineering situation of global poverty, undernourishment and malnutrition, the developing nations will take the first hit. They already have. Others will follow suit.

“The violence that exists in the human heart is also manifest in the symptoms of illness that we see in the Earth, the water, the air, and in living things”

(Pope Francis)

One of the many things that makes humans special from the rest of the animal kingdom is their diverse dietary needs – they rely not just on the fruits of our toil, but also on the flesh and produce of certain animals. While the continuity of various crops dangles on thin ice, the fate of animals (and the animal kingdom, as a whole) also hangs on a balance. Lands are riddled with increasing prevalence of droughts and depleting yields. Eutrophication is accelerating beyond control, and water bodies are deprived of the necessary conditions to regulate life within. In effect, habitats are altered or become inhabitable – the warming ocean bodies are already pushing schools of fish away from their original habitats. Migration carries with it the potential risk of an epidemic outbreak – the fresh wounds from the coronavirus outbreak should be enough to sum up the detriments of the latter. Adding fuel to the fire, the woes of water- and air-pollution are threatening to adulterate the food chain at large – clean water bodies, for instance,are be robbed of the purity and benefit it was meant to offer. The 1956 Minamata outbreak in Japan is as good an example as any.

Breathing nowadays feels like playing with fire – with an abundance of noxious and toxic gases present in the air we breathe, one improves the odds of physiological impairments and mortality. And with the increasing concentration of ozone and greenhouse gases, nature’s self-cleansing protocol is violated – the pollutants are unable to escape even the troposphere (our breathing space). Even in small quantities, this poisonous cocktail of gases poses an existential threat of grave repercussions. These gases silently pile up within the respiratory or circulatory systems, accumulating to the point where they are no more a drop of poison; rather, an ocean of it.

If the aforementioned fails to serve its purpose, then perhaps economic woes might titillate the conscience of the ‘dollar-guided’. Undeterred increments of temperature and climatic detriments would mean a drastically-abridged fertility of the lands that we rely on. Crops will fail to mature efficiently. The products do not command the same value as it used to. The swelling of droughts and siltation has made land unsuitable for any use, let alone agriculture or construction. The livelihoods of people dependent on such lands has gravely contracted, adding to the woes of different socio-economic classes within. Anomalous calamities – acid rains, storms and otherwise – are reigning supreme. Land is losing its value in more ways than just economic ones – the price tag means nothing if it can’t satiate the socioeconomic and necessitated value that it ought to deliver.

“There is one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate”

(Barack Obama)

If something needs to be done, it needs to be done now rather than later. And as common wisdom dictates, if there is a will, there is a way – or better still, if there is a will, there is unity. The existential threat is real. There is no denying the harrowing climate statistics – humans tend to aberrate from the truth, but numbers do not lie. It is time to carry the mantle of change ourselves as well and face the looming threat with a cohesive front. Unity has helped generations, and its time the twenty-first century jumped leaps and bounds itself. The lives of the generations to follow depends on how we act today. Time for more Thunbergs and Gores.

“People need to stop financing denial of climate change”

(Al Gore)

For that to happen, an army needs to be raised. The curtains of ignorance must be removed from the field of sight of as many people as possible. Current technological capabilities make it possible to engage more people with facts and information, especially in the way that is understood by a specific person – there is no one-size-fits-all, and the gap between the knowing and otherwise must be mitigated through the way one understands. This is where a robust, rightly-guided and unbiased media takes the spot light – infomercials and public awareness programs must be tailored to local needs (or, rather, the needs of the viewers it hosts). Governmental and not-for-profit organizations of every country must invest the necessary resources – be it time, finance, human capital, and so on – to embark on educating its citizenry. With a plethora of media to capitalize on, this would not be difficult task.

“We must now agree on a binding review mechanism under international law, so that this century can credibly be called a ‘century of [decarbonization]”

(Angela Merkel)

Shiny enterprises and state-of-the-art legislations might look good on paper, but the entire exercise fails if one does not walk the talk – there is no point of a legislation without legally-binding commitments. The relative successes of the Kyoto Protocol are an example of the wonders compliance can do for the world (though one may argue against its efficacy and shortcomings). Moreover, there is no point for a nation to attend a Convention and sign an MEAjust for the sake of the ‘almighty vote-bank’ and leaving it unratified. Even more baffling is the curious case of advanced economies like the US and Canada rashly pulling out of ratified agreements like the Paris Accord – if the world leaders want to inspire and lead by example, they are not doing a very good job at it. Now is not the time of personal interests; mother nature does not discriminate between the rich and poor, white and dark, man and woman, the affluent and poor-struck, and so on. Its’s tongue is one and not bound by any language, and the message is one and same for all; when such is the case, shouldn’t our response follow suit?

“Be part of the solution, not the problem”

(Stephen R. Covey)

The next steps, on an individual and communal level, are self-explanatory – making amends with mother nature. The adulteration of the environment needs to be curbed. For such to happen, existing and prospective pollution-control policies must be undertaken. Carbon-reduction commitments must be expedited to the maximum possible. The fight against ozone-depleting substances must be won at all costs. Redundant and polluting technology and practices must be phased out – it is heartwarming to see a keen player like Pakistan taking big steps in alternating the traditional brick kilns with the modern-day zig zag kilns, or imposing sanctions on stubble-burning to combat the issue of smog and air pollution. If trees are meant to be cut down, the same (or more) must be given back to the Earth – afforestation and reforestation must become common practice (one is again reminded of Pakistan’s awe-inspiring ‘Billion Tree Tsunami’ project).Economic and social incentives must take root if one is to lure the affluent – tax incentives for adopting, or shifting to, green technology is a good start. Appropriate penalties must hold the miscreants at bay. Humanity’s reliance on fossil fuels in its energy mix must cease to exist. Renewable resources must be sought and exploited to the fullest.

It does not stop here. Municipal and household wastes must be properly disposed. Trash must end up in the correct bin. Vehicles should not emit noxious and unhealthy gases, for which battery-operated engines or green-tech (such as catalytic converters) should do the trick. Industries and pollution hotspots must be built far away from residential areas and water bodies. Emissions should be filtered for toxic gases – a plethora of scrubbers, electrostatic precipitators and filtering technologies are available. Sanctuaries must be built to preserve depleting flora and fauna species. Water bodies must be purified of any non-degradable and poisonous litter it harbors. And the list goes on and on.

“We have a single mission: to protect and hand on the planet to the next generation”

(Francois Hollande)

There is so much to do, but so little time to do everything. Climate change must be taken seriously. The time is past when humanity thought it could selfishly draw on exhaustible resources and do as it please. We all know now that Earthis not a commodity. The battle is lost, but the war is not over(yet). And while the damage has been done, it is not too late to make amends. The lives of our children and theirs hangs in the balance. Solutions to the crisis are within reach, but in order to capture them, we must take urgent action today across every level of society. In order to do so, we need to gather our brains and take helm of the battleground. Climate change has united mankind more than ever, and it’s a race against time and odds. No one says it better than Christine Legarde:

“It is a collective endeavor, it is collective accountability, and it may not be too late”

The debate is no more about the legitimacy of climate change. It is about whether we will live to tell the tales of our successes. Will we make history or become a part of it? The victor at the end of the war will surely know the answer to this.

The Meeting Point between Pandemic and Environmental

Published

on

Humans in the Anthropocene

Humans are born from history, on the other hand, history is born from human life. Currently, humans have been in the Anthropocene, the era after the Holocene, a time when humans were more powerful in nature. This results in an imbalance of give and take activities between humans and the nature they inhabit. With rapid population growth, human needs will also increase. This increase in human needs will have an impact on the availability of existing natural resources. Exploitation of natural products such as coal, natural gas and others, this is accompanied by waste from production and human activities that produce waste in many sectors of life. What has been exploited by humans the impact is no longer comparable to what nature gives. Although nature has the ability to self-regenerate, but with human activities that are so aggressive in this era of globalization, it defeats the natural processes of nature. The presence of factories around the world after the steam engine and the industrial revolution occurred, weapons such as missiles, atomic bombs as a means of war for fellow humans, rockets and all kinds of vehicles of human ambition to export nature, all produce residual waste that is released, resulting in a large carbon footprint. affect the atmosphere which is as a protector and temperature regulator on earth. Not to mention the mining of many other crops.

The question that may often be asked but doesn’t need to be answered is “why should humans care about all that?”

In the last 100 years, the earth’s average temperature has increased between 0.4 to 0.8 C. The ambition of the countries in the world today is 1.5 degrees Celsius, whereas humans are facing the risk of an increase of 4 degrees, which means it will be the same with the temperatures that occurred between the Ice Age and the Holocene. In other words, humans are still far behind with the rate of destruction that exists. This warming will result in the emergence of many disasters in human life. Global warming is expected to cause the glaciers at both poles to melt and make the volume of sea water increase, most likely some islands on earth are at risk of sinking, especially the Indonesian archipelago which is a young land in geological history. Not only that, other impacts will be felt on climate change, a matter of months, days, seasons. Nature which is the main benchmark for farmers, fishermen and various sectors of work related to climate and seasons will feel a prediction crisis, several regions in Indonesia experience crop failures due to the calculations they do based on seasonal calculations are no longer accurate, even though these calculations have been passed down from generation to generation. inherited. But climate change and global warming have messed up astronomy. Maybe this is also what makes the Mayan calendar (piktun) only predict until 2012.

Not only the estimated harvest season, natural imbalances also cause the spread of disease vectors from animals to humans. Until now there has been no single plausible theory that definitely and accurately explains where COVID-19 came from and how it will disappear. Research is still being done, all theories put forward by scientists can be true. But scientists who study the environment, viruses, pandemics, health have found this conundrum, which all starts with “environmental imbalance”. If we describe briefly, in the food chain there is one missing which then results in advantages and disadvantages between predators and prey. If the rice field snakes are hunted by farmers, the rats will live more, and then they will eat the rice too, eventually the farmers will fail to harvest. Likewise, the case of COVID-19, with the large number of killings of wildlife, has shifted the pattern of the food chain.

Covid 19 and the balance of nature

There are many theories that explain the origin of the pandemic that humans are experiencing now, but until now there is no definite news about where the origin and cause of the catastrophe exists. US intelligence agencies say they may never be able to identify the origins of Covid-19, but they have concluded the virus was not created as a biological weapon. Apart from the specifics of covid 19 which is a virus, whose existence can never be seen with the naked eye, a number of scientists believe that the covid 19 pandemic occurs due to natural imbalances. The COVID-19 pandemic which was determined by the World Health Organization (WHO) or world health agency on March 11, 2020, could also occur due to the interruption of the food cycle which resulted in the explosion of a component of life without a predator in the same period of time.

The SARS-VoV-2 virus is a disease that originates from animals and is transmitted to humans. It is possible that the disease originated in bats, then spread through other mammals.

Even though it is not made in a laboratory, it does not mean that humans have no role in the ongoing pandemic. A recent study by scientists from Australia and the US found that human actions on natural habitats, loss of biodiversity and destruction of ecosystems contributed to the spread of the virus.

The number of infectious diseases has more than tripled every decade since the 1980s. More than two-thirds of these diseases come from animals, and about 70% of that number comes from wild animals. Infectious diseases that we know, for example: Ebola, HIV, swine flu and bird flu, are diseases that can be transmitted from animals to humans.

COVID-19 is also spreading rapidly as the world’s population is becoming more and more closely connected. This situation that surprised many people, had actually been warned by scientists for a long time. Joachim Spangenberg, Vice President of the European Institute for Sustainability Research, said that by destroying ecosystems, humans create conditions that cause animal viruses to spread to humans. “We created this situation, not the animals,” said Spangenberg. In 2016 UNEP Frontier has been warned that at least every four months a new zoonotic disease will emerge. This is due to human activities as follows:

Deforestation and habitat destruction

because humans are increasingly opening up areas inhabited by wild animals to graze livestock and take natural resources, humans are also increasingly susceptible to pathogens that have never previously left the area, and leave the bodies of the animals they inhabit.

“We’re getting closer to wild animals,” said Yan Xiang, a virologist at the University of Texas Center for Health Sciences. “And that puts us in touch with those viruses.” While David Hayman, professor of infectious disease ecology at Massey University, New Zealand said, the risk is also increasing not only through humans entering natural habitats, but also through animals. human pet

In addition, the destruction of ecosystems also has an impact on which types of viruses thrive in the wild and how they spread.

David Hayman emphasized, in the last few centuries, tropical forests have been reduced by 50%. This has a very bad impact on the ecosystem. In a number of cases, scientists have succeeded in revealing, if animals at the top of the food chain went extinct, animals at the bottom, such as mice that carried more pathogens, took their place at the top of the food chain.

“Each species has a special role in the ecosystem. If one species takes the place of another, this can have a major impact in terms of disease risk. And often we can’t predict the risk,” explains Alica Latinne of the Wildlife Conservation Society.

Evidence showing a link between the destruction of ecosystems and the increased risk of spreading new infections has led experts to emphasize the importance of the concept of “One Health”.

Wild animal trade

Markets selling wild animals and products from wild animals are another incubator for infectious diseases. Scientists consider it very likely that the SARS-CoV-2 virus that causes the disease COVID-19 emerged in a wild animal market in Wuhan, China.

Spangenberg explains that placing sick and stressed animals in cramped cages is an “ideal way” to create new pathogens, and spread disease from one species to another. Therefore, many scientists have urged the holding of stricter regulations for the wild animal market.

That is also the call of Elizabeth Maruma Mrema, Chief Executive of the Secretariat of the UN Convention on Biological Diversity. He has called for a worldwide ban on wild animal markets. But Mrema also reveals that for millions of people, especially in poorer regions of the world, these markets are a source of income.

Indonesia’s position in the eyes of the world

Indonesia is a country with a very large tropical forest, in COP 26 it was stated that Indonesia is the last bastion of planet earth along with the Amazon and the Congo forests. save a lot of germplasm, Indonesia’s forest area totals 128 million ha. Indonesia is a country with the third largest tropical rainforest in the world. That means, a lot of germplasm stored in it. This will also be a big scourge if the vast forest cannot be maintained properly. The expansion of residential areas, planting of oil palm, clearing land and roads will destroy some of the existing germplasm. Currently, humans have lost 8% of animal species and another 22%. If Indonesia participates in efforts to reduce and destroy the environment intentionally or unintentionally, we can estimate what will happen in the future.

How do greenhouse gases actually warm the planet?

Published

on

Greenhouse gas (GHG) emissions – the atmospheric gases responsible for causing global warming and climatic change – are critical to understanding and addressing the climate crisis. Despite an initial dip in global GHG emissions due to COVID-19, the United Nations Environment Programme’s latest Emissions Gap Report (EGR) expects a strong rebound in 2021, when emissions are expected to be only slightly lower than the record levels of 2019.

While most GHGs are naturally occurring, human activities have also been leading to a problematic increase in the amount of GHG emitted and their concentration in the atmosphere. This increased concentration, in turn, can lead to adverse effects on climate. Effects include increases in the frequency and intensity of extreme weather events – including flooding, droughts, wildfires and hurricanes – that affect millions of people and cause trillions in economic losses.

The Emissions Gap Report found that if we do not halve annual GHG emissions by 2030, it will be very difficult to limit global warming to 1.5°C compared to pre-industrial levels by the end of the century. Based on current unconditional pledges to reduce emissions, the world is on a path to see global warming of 2.7 °C by the end of the century compared to pre-industrial levels.

“Human-caused greenhouse gas emissions endanger human and environmental health,” says Mark Radka, Chief of UNEP’s Energy and Climate Branch. “And the impacts will become more widespread and severed without strong climate action.”

So how exactly do GHG emissions warm the planet and what can we do?

What are the major greenhouse gases?

Carbon dioxide (CO2), methane and nitrous oxide are the major GHGs. CO2 stays in the atmosphere for up to 1,000 years, methane for around a decade and nitrous oxide for approximately 120 years. Measured over a 20-year period, methane is 80 times more potent than CO2 in causing global warming, while nitrous oxide is 280 times more potent.

Coal, oil and natural gas continue to power many parts of the world. Carbon is the main element in these fuels, and when they’re burned to generate electricity, power transportation or provide heat, they produce CO2, a colourless, odourless gas.

Oil and gas extraction, coal mining and waste landfills account for 55 per cent of human-caused methane emissions. Approximately 32 per cent of human-caused methane emissions are attributable to cows, sheep and other ruminants that ferment food in their stomachs. Manure decomposition is another agricultural source of the gas, as is rice cultivation. 

Human-caused nitrous oxide emissions largely arise from agriculture practices. Bacteria in soil and water naturally convert nitrogen into nitrous oxide, but fertilizer use and run-off add to this process by putting more nitrogen into the environment.

What are the other greenhouse gases?

Fluorinated gases – such as hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride – are GHGs that do not occur naturally. Hydrofluorocarbons are refrigerants used as alternatives to chlorofluorocarbons (CFCs), which depleted the ozone layer and were phased out thanks to the Montreal Protocol. The other gases have industrial and commercial uses.

While fluorinated gases are far less prevalent than other GHGs and do not deplete the ozone layer like CFCs, they are still very powerful. Over a 20-year period, the various fluorinated gases’ global warming potential ranges from 460–16,300 times greater than that of CO2.

Water vapour is the most abundant GHG in the atmosphere and is the biggest overall contributor to the greenhouse effect. However, almost all the water vapour in the atmosphere comes from natural processes. Human emissions are very small and thus relatively less impactful.

What is the greenhouse effect?

The Earth’s surface absorbs about 48 per cent of incoming solar energy, while the atmosphere absorbs 23 per cent. The rest is reflected back into space. Natural processes ensure that the amount of incoming and outgoing energy are equal, keeping the planet’s temperature stable,

However, GHGs, unlike other atmospheric gases such as oxygen and nitrogen, are opaque to outgoing infrared radiation. As the concentration of GHGs in the atmosphere increases due to human-caused emissions, energy radiated from the surface becomes trapped in the atmosphere, unable to escape the planet. This energy returns to the surface, where it is reabsorbed.

Since more energy enters than exits the planet, surface temperatures increase until a new balance is achieved. This temperature increase has long-term climate impacts and affects myriad natural systems.

What can we do to reduce GHG emissions?

Shifting to renewable energy, putting a price on carbon and phasing out coal are all important elements in reducing GHG emissions. Ultimately, stronger nationally determined contributions are needed to accelerate this reduction to preserve long-term human and environmental health.

 “We need to implement strong policies that back the raised ambitions,” says Radka. “We cannot continue down the same path and expect better results. Action is needed now.”

During COP26, the European Union and the United States launched the Global Methane Pledge, which will see over 100 countries aim to reduce 30 per cent of methane emissions in the fuel, agriculture and waste sectors by 2030.

UNEP has outlined its six-sector solution, which can reduce 29–32 gigatons of carbon dioxide by 2030 to meet the 1.5°C warming limit. UNEP also maintains an online “Climate Note,” a tool that visualizes the changing state of the climate with a baseline of 1990.

Despite the challenges, there is reason to be positive. From 2010 to 2021, policies were put in place which will lower annual emissions by 11 gigatons by 2030 compared to what would have otherwise happened.

Through its other multilateral environmental agreements and reports, UNEP raises awareness and advocates for effective environmental action. UNEP will continue to work closely with its 193 Member States and other stakeholders to set the environmental agenda and advocate for a drastic reduction in GHG emissions.

Beyond these movements, individuals can also join the UN’s #ActNow campaign for ideas to take climate-positive actions.

By making choices that have less harmful effects on the environment, everyone can be part of the solution and influence change. Speaking up is one way to multiply impact and create change on a much bigger scale.

The social aspect of biodiversity reduction in Brazil

Published

on

What most people ignore is that climate change is also a social issue, arising from unawareness of the human population about the impact of their activities. Biodiversity plays a key role in ecosystems and also services benefits to the tourism industry. Marine life biodiversity specifically plays a role in attracting tourists for activities like scuba diving, snorkeling and other observation activities alike. Currently, the Brazilian Guitarfish, commonly found in the South Atlantic Brazilian waters, specifically around the South coast of Rio De Janeiro is facing massive decline in numbers, and is also on the list of critically endangered species.

One major reason for the rapid decline in numbers of Brazilian Guitarfish is overfishing of the female population for illegal, highly valued meat sale in fish markets. Most fishermen catch the female guitarfish along with their little offspring in shallow waters around Rio De Janeiro. The decline in species of guitarfish is mostly among the female population, however this impacts the long term numbers of the guitarfish population. Fishermen who catch guitarfish and engage in the illegal meat industry know little about the impact created by their fishing activities on biodiversity in the oceans. A valid solution to solving the issue of high levels of guitarfish fishing in Brazil is empowering fishermen to engage in other trades and businesses that are more sustainable with steady profits, simply raising awareness about the downside of overfishing endangered species might not be enough. A dollar is a dollar, or in this case a real is a real.

An alternate model for sustainable fishing has been developed in Fuji, specifically to protect the coastline that attracts tourism across the year. The local government in fishing villages is working in collaboration with fishers to ensure that they have access to a greater number of opportunities, even outside the fishing industry. Moreover, the local government is regulating the prices of fish meat and creating a bandwidth for sustainable profits by encouraging fishing of species that are more abundant in the local waters. This is creating a low incentive situation for Fujian fishers to fish endangered species and engage in local trade. This unique model, with a mix of government involvement and local incentives, can be amplified to other countries like Brazil too.

While most experts talk about climate change, they ignore the social aspect of climate change, which is perhaps the biggest contributor. Human activities impacting climate change don’t just arise from unawareness but also from lack of other opportunities that can incentivise a change in decision making. Creating consumer end awareness about the downside of consuming illegal meat is also crucial. The same can be done in fish markets with the use of artwork to support behavioral change. Brazilian Guitarfish also carry high content of Mercury and chemicals and are therefore not the safest to consume in the unregulated illegal meat industry, without safety approvals from the government. Making consumers aware about the fact that they are not just paying high prices for meat that is illegal but also consuming meat that can potentially give them cancer and other diseases is crucial. This can be done using artwork in fish markets, as is being done across fishing villages in Bali.

Brazilian Guitarfish are also rare in other parts of the world and attract divers to premium diving locations, fetching around $75 to $100 per dive, higher than most other locations where rare species like Guitarfish cannot be spotted. More efforts can be taken to set up dive centers in Brazil specifically dedicated towards Brazilian Guitarfish. This will not only be an attractive source of income for locals but also encourage conservation efforts. Tourism can be a major source of revenue for Brazilian fishermen and farmers, encouraging development and infrastructural promotion across major cities in Brazil, thereby creating a line of opportunities for Brazilian citizens across different industries.

With biodiversity as high as Brazil, more efforts should be taken to fuel tourism, interaction and awareness with Brazilian biodiversity, including rainforests and marine life. With the empowerment of local communities, we can together create a more sustainable future, inclusive towards all organisms.

To promote the cause of Brazilian Guitarfish conservation, I have started a movement called The Brazilian Guitarfish movement, operating via  whatsapp group involving people across continents from various fields – climate researchers, marine conservationists, scuba divers, fishing industry experts, government authorities, public policy enthusiasts and tourism officials to curate solutions specific to conserving Brazilian Guitarfish. It’s a global initiative, with hands contributing from across the world to save Brazilian Guitarfish by empowering local fishers with diverse opportunities. There is always an alternate solution, sometimes all we need is a fresh approach along with fresh minds to find it. Fortunately, connecting globally in the digital world makes problem solving  easier for all of us.
