Coral Reefs: The Rainforests of the Sea Are Dying — Can We Save Them?

Imagine a city beneath the sea — a sprawling, three-dimensional metropolis of intricate architecture, blazing with colour, teeming with life, every surface occupied by a different organism going about its own intricate life. This is what a healthy coral reef looks like. It is one of the most complex, diverse, and beautiful ecosystems on Earth, the product of millions of years of co-evolution between thousands of species. And it is dying before our eyes. 

Coral reefs cover less than 1% of the ocean floor, yet they are home to more than 25% of all marine species. Approximately 4,000 species of fish depend on coral reefs. They support over 1 million species of plants and animals in total. For comparison, tropical rainforests — widely recognized as the most biodiverse terrestrial ecosystems — cover about 6% of land but support only slightly more species than reefs cover from their much smaller area. Coral reefs are, hectare for hectare, the most biodiverse places on Earth. 

Corals are extraordinary organisms. Each coral 'head' is actually a colony of thousands of tiny animals called polyps, living in a calcium carbonate skeleton they secrete themselves. Inside each polyp live microscopic algae called zooxanthellae, which use photosynthesis to produce most of the coral's food. This partnership between animal and algae is one of the most important and ancient symbioses in nature — but it is also extremely fragile. 

When water temperatures rise even slightly above the coral's normal range — by as little as 1°C for an extended period — the coral becomes stressed and expels its zooxanthellae. Without its algal partners, the coral turns white (a process called bleaching) and begins to starve. If temperatures return to normal quickly, corals can recover. But if the heat stress persists, or if bleaching events happen too frequently for the coral to recover between them, the coral dies. 

Climate change is making bleaching events more frequent, more severe, and more widespread. The Great Barrier Reef — the world's largest coral reef system, stretching 2,300 kilometres along Australia's northeastern coast — has experienced five mass bleaching events since 1998, the last three in consecutive years. Each event kills corals that took decades or centuries to grow. The reef that exists today is measurably smaller and less diverse than the reef of fifty years ago, and scientists are openly discussing whether it can survive the coming decades. 

India's coral reefs face the same existential threats, plus several additional local ones. The coral reefs of the Gulf of Mannar, Lakshadweep, and the Andaman and Nicobar Islands are all showing signs of bleaching and degradation. Coastal pollution from urban sewage and agricultural runoff fuels algae growth that smothers corals. Destructive fishing practices — dynamite fishing, bottom trawling, the collection of ornamental fish using cyanide — cause direct physical damage. Unsustainable coastal tourism introduces anchor damage and pollution. And the coral mining that once destroyed large areas of reef in the Gulf of Mannar, though now banned, has left lasting scars. 

Can coral reefs be saved? The answer depends almost entirely on how quickly and decisively humanity acts to address climate change. Even the most ambitious reef restoration projects — coral gardening, coral transplantation, assisted evolution to develop heat-resistant coral strains — cannot outpace bleaching if global temperatures continue to rise. The single most important action for coral reef survival is reducing greenhouse gas emissions to net zero as rapidly as possible. 

But in parallel with climate action, protecting reefs from local stressors can buy them time and increase their resilience. Establishing well-enforced marine protected areas, eliminating destructive fishing practices, reducing coastal pollution, and managing tourism sustainably all help reefs cope better with climate stress. India must do more in all of these areas. The coral reefs off our coasts are a national treasure, a source of biodiversity, food security, tourism income, and coastal protection. Losing them would be an irreversible catastrophe.

Women and the Environment: Why Gender Equality Is a Climate Solution

Today, on International Women's Day, the Green World blog wants to celebrate a truth that the mainstream environmental movement has been too slow to acknowledge: women are not just victims of environmental degradation — they are the most powerful environmental stewards on Earth. From the forests of Kenya to the rivers of India, from the fields of Bangladesh to the fishing villages of Tamil Nadu, women are the frontline defenders of the natural world, and empowering them is one of the most effective climate solutions available to humanity. 

The connection between women and the natural environment runs deep and is not merely metaphorical. In rural communities across the developing world, women are the primary users and managers of natural resources at the household level. They collect water — often walking several kilometres to and from wells or rivers. They gather firewood for cooking and heating. They tend kitchen gardens that supplement family nutrition and income. They manage household waste. They make the daily decisions that determine how much water, energy, and food a household consumes. 

This intimate, practical relationship with natural resources gives women both a profound stake in environmental health and a wealth of ecological knowledge that formal science is only beginning to document. Indigenous and rural women have accumulated detailed knowledge of local plant species, seasonal patterns, water sources, and land management practices over generations. This knowledge is irreplaceable — and it is at risk of being lost as traditional practices are eroded by urbanization and cultural change. 

When the environment degrades — when wells dry up, forests disappear, soils fail, and fish populations collapse — it is women who bear the first and heaviest burden. As water sources move farther away, it is women and girls who walk farther to fetch water. As fuelwood becomes scarce, women spend more time gathering it and more time cooking over smoky, inefficient fires that damage their health. As crop yields fall due to climate change and soil degradation, it is often women — who do most of the farming in rural India and across the developing world — who must work harder for less return. 

The Chipko movement of the 1970s is the most celebrated example of women's environmental leadership in India, but it is far from unique. Women in Uttarakhand's villages locked arms around trees to prevent commercial loggers from felling them, understanding intuitively that the forests were the source of the water, fuel, and fodder their families depended on. The movement gave birth to India's modern environmental consciousness and inspired conservation movements around the world. 

Research consistently demonstrates that when women have secure land rights, access to credit and technology, and participation in environmental governance, the results are better outcomes for forests, water bodies, and biodiversity. Community forest management groups with significant female participation in Nepal, Malawi, and India consistently achieve better conservation outcomes than male-dominated groups. Women-led water management committees in rural Rajasthan have restored springs, revived degraded watersheds, and improved water security for entire villages. 

Climate change and gender inequality are also deeply intertwined. Climate change makes the work that women do — growing food, managing water, caring for families — harder and less certain. And women, because they have less access to information, early warning systems, financial resources, and mobility, are more vulnerable to climate disasters. The 2004 Indian Ocean tsunami killed disproportionately more women than men; so did the 2019 and 2020 cyclones in Odisha. 

Empowering women — through education, economic opportunity, land rights, participation in governance, and access to technology — is therefore one of the highest-leverage investments a society can make in its environmental future. Project Drawdown, which has ranked climate solutions by their potential impact, identifies education for girls and women's empowerment as among the top climate solutions globally. On this International Women's Day, let us commit to recognizing, supporting, and amplifying women's environmental leadership at every level, from the village to the global summit.

Climate Refugees: The Human Face of the Climate Crisis

In 2023, extreme weather events displaced approximately 26 million people from their homes — more than conflict and violence combined for the first time in recorded history. These are the world's climate refugees: people forced to flee not by war or political persecution, but by rising seas, more intense cyclones, prolonged droughts, catastrophic floods, and the slow, grinding degradation of the land and water resources they depend on for survival. 

The word 'refugee' still does not officially apply to people displaced by climate change under international law. The 1951 Refugee Convention protects people fleeing political persecution, but offers no legal protection to those fleeing climate-induced disasters. This legal gap leaves climate-displaced people in a precarious position, unable to access the protection, support, and resettlement options available to recognized refugees. Closing this gap is one of the most urgent human rights challenges of our time. 

The stories of climate displacement are heartbreaking in their specificity. In the Sundarbans of West Bengal, families who have lived on the same islands for generations are watching their land sink beneath the rising Bay of Bengal, metre by metre, year by year. In coastal Odisha and Andhra Pradesh, fisher communities are being forced inland by the increasing frequency and intensity of cyclones. In Rajasthan and Bundelkhand, prolonged droughts are emptying entire villages as farmers who can no longer grow crops or find water migrate to already overcrowded cities. 

Bangladesh is often cited as ground zero for climate displacement. The country is one of the most densely populated and climate-vulnerable nations on Earth. Rising sea levels, increasing salinity in coastal farmland, intensifying cyclones, and Brahmaputra River flooding are already displacing hundreds of thousands of Bangladeshis every year, many of whom migrate to Dhaka or attempt to cross into India. The scale of future displacement, absent dramatic global climate action, is almost incomprehensible. 

Sub-Saharan Africa presents another dimension of the crisis. In the Sahel region, a decades-long desertification trend driven by climate change, overgrazing, and deforestation is shrinking the area of productive farmland and pastoral land available to tens of millions of people. Competition over water and grazing rights is fuelling conflict. Young men with no economic future in their home communities are moving to cities or attempting the desperate journey across the Mediterranean to Europe — not primarily because of war, but because their land can no longer support them. 

The Internal Displacement Monitoring Centre projects that without ambitious climate action, climate change could force over 1 billion people to migrate by 2050. To put this in perspective, the entire human population of the Earth was 1 billion in the year 1800. We could see, in a single century, a forced displacement of people larger than the entire world population of two hundred years ago. The humanitarian system, already stretched to breaking point, simply cannot absorb this scale of displacement. 

India is both a major contributor to climate change through its historical and current emissions, and one of the countries most vulnerable to its impacts. The Indian government has committed to ambitious climate targets, and India's renewable energy transition is genuinely impressive. But ambition must translate into action at the speed and scale that the science demands — not just for India's own sake, but out of solidarity with the most vulnerable communities within India and around the world. 

The climate crisis is fundamentally a justice issue. The people being displaced by climate change today — in Bangladesh's deltas, India's coastlines, Africa's drylands — are overwhelmingly the people who have contributed least to the greenhouse gas emissions that are causing it. They deserve not just our sympathy but concrete action: aggressive emission cuts, robust adaptation funding, and a legal framework that recognizes and protects climate refugees. Climate justice is not a slogan. It is an obligation.

Plastic Pollution: The Ocean's Invisible Enemy

 

Every year, approximately 8 million tonnes of plastic waste enter our oceans. That is the equivalent of dumping one garbage truck of plastic into the sea every single minute. By 2050, if we do not act, there could be more plastic in our oceans than fish.

Plastic never truly disappears. It breaks down into smaller and smaller pieces called microplastics, which are now found in the deepest ocean trenches, the highest mountain snowfields, and even inside the human body. Scientists have detected microplastics in human blood, lungs, and breast milk.

Marine animals suffer terribly. Sea turtles mistake plastic bags for jellyfish. Seabirds feed plastic fragments to their chicks. Whales wash ashore with stomachs full of plastic bags and nets.

The solution starts with us. Refuse single-use plastics. Carry a cloth bag. Say no to plastic straws. Support brands that use sustainable packaging. And demand stronger government policies to hold manufacturers accountable.

The ocean is not a dumping ground. It is the cradle of all life on Earth. Let us protect it.

Pope Francis stresses 'right to environment' in UN speech

Pope Francis has urged a large gathering of world leaders at the United Nations in New York to respect humanity's "right to the environment".

He also called on financial agencies not to subject countries to "oppressive lending systems" that worsen poverty.

In an allusion to the Church's teachings on sexual minorities, he called for respect for the "natural difference between man and woman".

He went on to visit the 11 September memorial for a multi-faith service.

After a silent prayer, the pontiff met relatives of some of the victims of the attack in 2001.

Pope Francis later visited a Catholic school in the heavily Hispanic New York neighbourhood of East Harlem.

The crowd in the gym of Our Lady Queen of Angels School included more than 100 immigrants, who greeted Francis with songs.

One eyewitness wrote on Twitter: "He's (Pope) having a blast in Harlem. Big smile. #PopeinNYC".

'Ideological colonisation'

In a wide-ranging speech at the UN, the Pope said the universe was "the fruit of a loving decision by the Creator" and that humanity "is not authorised to abuse it, much less to destroy it."

He said he hoped a forthcoming summit on climate change in Paris would produce a "fundamental and effective agreement".

He addressed topics including girls' education and drug trafficking. He welcomed the deal between Iran and world powers on its nuclear deal, calling it "proof of the potential of political goodwill".

He also condemned "ideological colonisation by the imposition of anomalous models and lifestyles which are alien to people's identity" in what was understood as a reference to Western support for gay and transgender rights in other countries.

At a memorial service at the September 11 Memorial Museum, he prayed for those killed in the attacks and for healing for their relatives.

Catholics in America:

• 80 million baptised as Catholics

• Six of the nine Supreme Court justices are Catholic

• 31% of the US Congress (22% general population)

• One Catholic president (JFK) and one vice-president (Joe Biden) in the history of the US

• Six Catholic Republicans running for 2016 presidential nomination, the most ever

About 80,000 people are expected to watch the procession as he makes his way to Mass at Madison Square Garden on Friday night.

Nearly 20,000 are set to attend the service at the major sporting and concert arena.

Thousands lined Fifth Avenue on Thursday evening as the Argentine pontiff made his way to St Patrick's Cathedral for evening prayers.

The Pope arrived in New York from Washington, where he delivered the first-ever papal address to the US Congress.

In the speech, he urged a humane response to migrants, an end to the death penalty and better treatment of the poor and disadvantaged.

Next he will go to Philadelphia, Pennsylvania, where he will speak in front of Independence Hall and celebrate Mass at a Catholic families' rally.

If someone were to set up a telephone booth sized box on your street filled with unwanted items — such as books, toys and small knick knacks, perhaps — and then topped it off with a “Free” sign, what do you think would happen?

If Switzerland is any indication, passersby turned salvagers and recyclers would appear out of nowhere, sifting their way through other people’s unwanted discards, thinking up ways to put their newfound discoveries to good (re)use. Some would even add their own unwanted items to the box.

Neighborhood exchange boxes have helped Geneva, Switzerland reuse 32 tons of goods thus far thanks to a program called BOÎTES D’ÉCHANGE ENTRE VOISINS–A box for exchange between neighbors. But can it work in other cities?

Started in 2011, people leave items that they do not want, and take items that they do want. It’s that simple.

Or is it?

The environmental benefits of increasing reuse are obvious, but from the project creator’s perspective, there’s more to the Neighbourhood Exchange Box program than just going green.

It’s also part urban art and part social experiment, providers of unusual opportunities to create social and cultural links between people in a neighborhood.

The program page explains:

Neighbourhood Exchange Box is a project which explores reciprocity between neighbours. It brings a new impulse into the neighbourhood and a sense of belonging and involvement to the local community by prompting opportunities of exchange and contact.

Behind it all is Happy City Lab, founded by Dan Acher, an “artivist” from Geneva focused on creating happy cities.

Most of us know by now that reducing and reusing are part of the answer to what our planet needs more of, so instead the program toils over questions like:

Nowadays, whilst most of our interactions depend on money, is it still possible to establish a completely disinterested form of exchange, without even knowing who the beneficiary is? Is it possible to extend such a project to the scale of a whole town? That of a region? A country? Further?
