Role of an individual being to save the green earth

Published

on

It is no secret that for decades, Earth has been incessantly abused, threatened, and destroyed. As man continues to put his selfish needs first, our environment suffers. The amount of destruction humans have caused in the past three decades is beyond comprehension – the glaciers in the poles are rapidly melting which is increasing the water level of the oceans; forests are quickly depleting; the percentage of greenhouse gases and other pollutants in the air is continuously rising, posing a threat to the already thinning ozone layer; energy reserves are exhausting, and the list goes on.

Isn’t it about time we started thinking about our beautiful planet and other life forms that inhabit it?

We all know that in an ecosystem, the well-being of one is closely and intricately related to that of another. Every living being – microorganisms, insects, animals, birds, plants – is dependent on each other for survival. The extinction of one species will naturally create an imbalance within the ecosystem, disturbing all other life forms within it.

Every individual has a role to play in preserving the Earth’s environment. A positive change, no matter how small, holds the ability to create a lasting ripple of change in the long run. Just imagine, if every individual all around the world (that is, 7 billion!) started doing their respective parts in reducing their carbon footprint and adopting the green way of living, how massive a change could we create! Taking baby steps and starting by adopting positive everyday habits could go a long way in saving the environment.

Here are a few things you, as an individual, could start doing to make this world a much ‘greener’ and better place.

  1. Adopt the 3R technique – Reduce, Reuse, and Recycle.

First, try to minimize wastage of resources and the domestic waste produced as much as possible. Buy only what you need, and it is a wise move to buy large packets(more quantity of product but less waste generated when it comes to packaging). Always reuse items that can be used more than once, such as grocery and shopping bags. Opt for washable utensils over disposable ones. Indulge in recycling products to create new products. People all around the world have come up with many unique ideas to recycle waste and create something new!

  1. Composting is the way to go!

Instead of dumping away the organic waste(vegetable and fruit peels, flowers, leaves, etc.) produced in your house daily in some landfill, try composting. Dig a pit in your backyard and start dumping the organic waste in it. When the hole is filled, cover it up with soil. The organic waste will decompose in several weeks and will serve as natural manure for the soil. This is the best way to start organic farming in your own backyard!

  1. Live Unplugged!

Always, always, remember to unplug used chargers from the sockets and switch off the lights, fans, and any other electrical appliance when not in use. You may not realize it, but these little acts of carelessness may be the reason behind your skyrocketing electricity bills. By switching off devices and appliances when not in use, you are not only cutting down on your energy costs but are saving a considerable amount of energy.

  1. Opt for energy efficient appliances

Replace the age-old and energy-hogging appliances in your home with the new, energy-efficient ones. Today, the market is filled with energy efficient bulbs, fans, heaters, air conditioners, TVs, refrigerators, and so much more. These devices deliver excellent performance while consuming minimal energy. Thus, the overall consumption of electricity in your house will reduce to a large extent, as will your utility bill.

  1. Plant Trees

Trees provide us with oxygen, shade, and bring rainfall. They are immensely needed to help combat the climate change that is taking the entire world in its grip. Do your part and make it a point to plant trees in your surrounding areas. You can take up the initiative during festivals or special occasions and create a tree plantation drive in your neighborhood. This way, you will encourage others to plant trees for a greener future.

Apart from these major steps, you can also save the Earth by doing the following:

Opt for public transport. Individual cars and automobiles not only increase the overall fuel consumption but also increase the air pollution every day. By riding public buses, trains, metros, etc., you can help reduce this.

Choose e-receipts and bills over paper bills. This will help save our forest resources.

Fix any leaks and cracks, in any, in the pipes, taps, and water cooling system in your homes. Every drop of water is precious.

Adopt rainwater harvesting. By collecting rainwater in clean containers or tanks, you can create an extra buffer of water for fulfilling your domestic purposes(washing cars, watering plants, etc.).

Say no to plastic bags. Use cloth or jute bags.

If each one of us starts following these steps, our Earth will become much greener and livelier in the years to come. Never forget, this is our only Home, and it is up to us to protect and preserve it.

Floods in Europe, Turkey, China and India

Published

on

The residents of Erfurt in Thuringia, where Martin Luther lived and studied, had never seen anything like it.  The main street became a raging river washing away parked cars and anything else besides that emerged from flooded first floors.

The flooding in northwest Germany and Belgium as the gentle meandering Ahr River transformed into a torrent, overflowing its banks and devastating this wine producing region stunned  Angela Merkel  by the extent of damage in the towns and valleys.  Close by in Schuld nearly half of the houses are completely destroyed, many simply disappeared, washed away, and the rest suffered serious damage.

West of Cologne, the Erft River submerged streets and houses in Blessem.  The sides of a gravel pit gave way as it filled with water and parts of a castle and several houses collapsed into the huge hole.  Southwest of Cologne in the Eifel region, the charming old-world tower of Ban Munstereifel was inundated and the charming pedestrian mall lined with centuries old buildings was ripped up by the waters.

The story was repeated in Liege, Belgium’s third largest city, as the Meuse River spilled over its banks and into the city turning the streets into rushing waters and carrying away cars, furniture and unfortunately, people.  The river had risen by about 10 feet in one day.  Almost all of Belgium was under flood alert as other rivers rose.  By the time it was over at least 20 had died, many were missing and the prime minister had declared a day of mourning.

Across the channel, a fierce storm flooded West London and affected subway tunnels bringing transport to a stop.  Again, roads turned into rivers as a month’s rain fell in one day.  Affecting large portions of southern England, it flooded rail lines even in Southampton.

Earlier in the month, tropical storm Elsa flooded subways in parts of New York.  Meanwhile, torrential rains have flooded subways in Zhengzhou, the capital of Henan province, trapping passengers.

The rains have battered the Chinese province for almost a week.  Home to more than 99 million, the region has suffered an estimated $190 million of damage.  At least 33 people are feared dead, 12 in the Zhengzhou subway when it was flooded.  Terrified survivors on Line 5 report water slowly rising up to their necks as they stood on the seats.  Dams have burst, reservoirs have overflowed as have rivers, affecting almost a half billion people according to People’s Daily. 

Catastrophic floods in Artvin Province in Turkey, this week repeat the story.  Cars washed away down streets turned into torrents when the cities of Artvin and Arhavi were inundated.  Also this week in India the monsoon season in Maharashtra has brought extremely heavy rains with flooding. 

The terms being used for these floods are ‘once-in-a-lifetime’ or ‘once-in-a-thousand-year events.  But the coincidence of so many of these across the globe begs the question of whether the climate crisis has altered the norm.  Will another of these ‘thousand-year’ events hit us next year or decade?  Time will tell.  Our hearts go out to the people who are suffering… those who have lost loved ones and those who have lost what they owned and their peace of mind.

Climate change could spark floods in world’s largest desert lake

Published

on

UNEP/Duncan Moore / 19 Jul 2021

For years it appeared as though Lake Turkana, which sits in an arid part of northern Kenya, was drying up.

Its main river inflows had been muffled by dams and many feared water levels were poised to drop by two-thirds, causing the lake to cleave into two smaller bodies of water. It was, one report said, an African “Aral Sea disaster in the making” – where only 10 per cent remains of the original sea.

But a new study from the United Nations Environment Programme (UNEP) predicts a far wetter future for Lake Turkana – and possibly a more perilous one for the 15 million people who live on its shores.

The report found that over the next 20 years, climate change could likely lead to heavier rains over Lake Turkana’s river inflows, which would raise water levels in the lake itself and increase the likelihood of severe flooding.

The study urged officials in Kenya and Ethiopia, which both border Lake Turkana, to prepare for a future in which once-rare floods, such as those that hit the region in 2019 and 2020, are regular occurrences.

“Many people think that climate change is a problem for the future,” says Frank Turyatunga, Deputy Head of UNEP’s Africa Office. “But as Lake Turkana shows, it’s happening now and it’s already forcing people to adapt to new conditions.”

Lake Turkana, the world’s largest desert lake, is part of the Omo-Turkana basin, which stretches into four countries: Ethiopia, Kenya, South Sudan and Uganda. The basin is home to many rare plants and animals.

Since 1988, Ethiopia has built a series of hydroelectric dams on its main tributary, the Omo River, leading to predictions of Lake Turkana’s demise.

Climate projections

Using sophisticated water resources modelling and climate change scenario analysis, the new UNEP report found that up to eight human settlements around the lake could be inundated by flooding periodically. While severe, abrupt flooding has been rare, climate change projections foresee this becoming more regular and impacting more people if adaptation measures are not put in place.

The report called for improved international cooperation and adaptation measures, including reforestation, agroforestry and avoiding construction in areas at risk of flooding.

“In the last two years, rising water levels in Lake Turkana have damaged pastureland, inundated buildings and forced people to flee their homes,” says Tito Ochieng, Director of Water in Kenya’s Turkana County. ”But there is still a mindset in Kenya that lake water levels are constantly falling, which makes planning difficult.”

The study also found evidence of rising water levels in the eight lakes that line Kenya’s Rift Valley. Severe flooding in those lakes in 2019 and 2020 damaged homes and infrastructure – and even reportedly led to a spike in deadly crocodile attacks.

Africa stands out disproportionately as the most vulnerable region in the world to climate change. This vulnerability is driven by the prevailing low levels of socioeconomic growth in the continent. While climate change is global, the poor are disproportionately vulnerable to its effects.

UNEP’s climate change work in Africa supports countries to implement their climate action commitments – Nationally Determined Contributions (NDCs) – to meet food security, create income and opportunities for youth, and economic expansion.

Regional cooperation

The report was part of a wider project designed to accelerate cooperation in the border areas between Ethiopia, Kenya and Somalia.

The project also developed an open-source information portal on the basin, based in part on satellite imagery. It contains data on land cover, water quality and soil moisture, and examines the various climate change scenarios.

The report follows the launch of the UN Decade on Ecosystem Restoration 2021-2030, a global push to revive natural spaces. It is also part of UNEP’s wider work to monitor and restore freshwater ecosystems worldwide, supporting Sustainable Development Goal 6.

Six things you can do to bring back mangroves

Published

on

Don’t be fooled by their modest appearance: mangroves are important players in some of the greatest challenges facing the world today. They provide a defense between land and sea, absorb carbon, contribute to economic and food security, and are home to some of the most rare and colourful species.

But mangroves are disappearing at an accelerating rate.In some areas of the Western Indian Ocean region – one of the two most important global mangrove hotspots, together with Southeast Asia – more than 80 per cent of mangroves have already been lost.

The United Nations (UN) Decade on Ecosystem Restoration is a global rallying cry to change our relationship with nature – from degradation to restoration. Here are six things you can do to start bringing back mangroves today.

1. Understand the importance of mangroves.

Only with healthy ecosystems can we enhance people’s livelihoods, counteract climate change, and stop the collapse of biodiversity.

UNEP research shows that mangrove ecosystems underpin global and local economies, by supporting fisheries, providing other food sources and protecting coastlines. In fact, every hectare of mangrove forest represents an estimated US$33–57,000 per year.  

They’re also important protectors – sheltering land and coastal communities from storms, tsunamis, rising sea levels and erosion. And with the world at risk of a temperature rise of over 3°C this century, mangroves are also an invaluable ally in the race to adapt. They extract up to five times more carbon from the atmosphere than forests on land, and protecting mangroves is 1000 times less expensive, per kilometer, than building seawalls.

Learn more about mangrove ecosystems in this short video; and their role in climate change adaptation in this animation.

2. Understand what is driving their loss.

Home to forty per cent of the world’s population, coastlines are among the most densely-populated areas on Earth. Consequent development of coastlines – clearing mangrove forests to create space for buildings, and to farm fish and shrimp – is the main driver of mangrove loss. Worldwide, this has caused the loss of 20 per cent of mangrove ecosystems. 

Pollution also plays a role. Because they form a protective line between coasts and ocean, mangroves are effectively a “plastic trap”. When plastic bags and litter cover roots and sediment layers, it can starve mangroves of oxygen; and can harm sea animals.

3. Make sustainable choices.

The choices we make are a powerful way to express our values and to affect consumption and demand. Ask questions about the food you consume; choose foods that are sustainably sourced; say no to single-use plastic and reduce consumption in general.   

Learn more about what you can do through the UN Environment Programme (UNEP) Clean Seas campaign, and see examples of restoration supportive choices in the Ecosystem Restoration Playbook.

4. Learn how restoration works.

Before planting new mangroves, it is important to understand the cause of forest degradation or disappearance. In the case of pollution, over-harvesting or other causes that can be eliminated, mangroves can recover naturally.

When recovery requires human intervention, it is important to follow key steps, like involving local communities, selecting native seedlings and establishing a functioning nursery. To learn more, see UNEP’s Guidelines on Mangrove Ecosystem Restoration, which elaborate each step of the process.

5. Be an advocate and an activist.

Whoever you are, wherever you are, you can begin to take action today. Discuss the importance of mangroves with your friends, family, colleagues and networks. Share information, images and ideas that inspire you.

If you’re not sure where to start, find inspiration in what others are doing. In Kenya and Madagascar, communities have recognized the contribution of mangroves to their own livelihoods and are actively participating in carbon monitoring, reforestation and education to prevent exploitation and ensure the livelihoods of future generations.

To get ideas about actions that could be right for you, play this game; and go to the UN Decade for Ecosystem Restoration Implementers Hub to find out how others are taking the lead in this work.

6. Make some noise.

Despite the scale of the challenge, there are solutions; and some governments are already taking action. Cuba, Haiti, Puerto Rico and the Dominican Republic have prioritized mangrove restoration through the Caribbean Biological Corridor initiative; and in Cuba, mangrove forests still cover 70 per cent of the coastline. Pakistan has committed to planting 10 billion trees by 2023 in an initiative led by Prime Minister Imran Khan and supported by UNEP, and millions – if not billions – of these trees will be mangroves. Restoration pledges from other countries can be found here.
