Every two seconds, an area of forest the size of a football pitch is lost to logging or destructive practices. Through agriculture and logging, mining and climate change, humans are wiping out irreplaceable forests - and the life that depends on them - at a terrifying pace.

We are losing not only our primeval forests, which regulate our climate and water resources, but also the amazing range of species that call them home. Indigenous peoples are pushed out as companies move in to destroy their ancient homes. It is estimated that almost 1.6 billion people around the world rely on forests to earn a living, and 60 million indigenous people depend on forests for survival.

China's disappearing forests

Only 3.34% of China's forests remain intact. The rest are threatened by plantations: in Hainan and Yunnan, for example, indigenous trees are felled to make way for fast-growing eucalyptus plantations, which are used to make paper pulp.

Unfortunately - though they both contain trees - plantations and ancient forests are not the same in terms of ecology. Ancient forests are crucial to biodiversity and provide habitats for many native species of animals and plants. They also store millennia-worth of carbon, which is released as carbon dioxide (a greenhouse gas) when the trees are logged.

Global Deforestation

Mainland China, Hong Kong and Taiwan also play a role in driving the destruction of ancient forests in other parts of the world, particularly the Paradise Forests, one of the last remaining rainforests in Indonesia and Papua New Guinea.

China is now the world's second largest consumer and importer of wood products, according to the United Nations. Because China faces not only limited forest resources but also booming domestic demand, most of its timber for export and domestic use has to be imported. Unfortunately, illegal logging is rampant in the Paradise Forests of Indonesia and Papua New Guinea, as well as the Congo. With such high rates of illegal logging and lack of awareness, it is very likely that much of China's imported timber comes from illegal sources.

Industrial logging for timber and pulp and paper has devastated much of the world's rainforests. Whole swathes of Indonesian rainforests and peatlands have been turned into paper pulp for toilet paper, tissues, magazines, and copy and print paper.

The global demand for palm oil (widely used in cosmetics and as a vegetable oil in food products), soy, and beef also drives massive rainforest destruction. China is the world's second largest importer of palm oil, surpassed only in 2010 by India. Much of the Amazon has been burned to make way for cattle ranches and soya plantations, while Indonesian rainforests are cleared for palm oil. In this way, irreplaceable rainforests are destroyed to make toothpaste, chocolate and animal feed.

Deforestation and Climate Change

Today, forests face another threat. Deforestation contributes to climate change - accounting for one-fifth of all greenhouse gas emissions. It is Indonesia's terrifying rates of deforestation alone that make this developing country the world's #3 greenhouse-gas emitter, behind China and the US. Indonesia's peatlands store 35 billion tons of carbon - and when they are drained and burned, all of this carbon returns to the atmosphere.

At the same time, climate change itself threatens forests on a terrifying scale.

Rising global temperatures damage and kill trees, and increase drought and forest fires. Dying trees release still more carbon, which further increases our global temperature. This cycle of forest collapse represents a critical feedback loop that could drive warming for centuries, change life cycles on Earth, and usher in a sweeping transformation of human civilisation. The surest way to stop it is to end deforestation.

Forests cover 31% of the land area on our planet. They help people thrive and survive by, for example, purifying water and air and providing people with jobs; some 13.2 million people across the world have a job in the forest sector and another 41 million have a job that is related to the sector. Many animals also rely on forests. Eighty percent of the world's land-based species, such as elephants and rhinos, live in forests. Forests also play a critical role in mitigating climate change because they act as a carbon sink-soaking up carbon dioxide that would otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns.

But forests around the world are under threat, jeopardizing these benefits. The threats manifest themselves in the form of deforestation and forest degradation. The main cause of deforestation is agriculture (poorly planned infrastructure is emerging as a big threat too) and the main cause of forest degradation is illegal logging. We're losing 18.7 million acres of forests annually, equivalent to 27 soccer fields every minute.

Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world's biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching. Deforestation in this region is particularly rampant near more populated areas, roads and rivers, but even remote areas have been encroached upon when valuable mahogany, gold, and oil are discovered.

WWF has been working to protect forests for more than 50 years. WWF works with governments, companies, communities and other stakeholders to promote certification for responsible forest management practices, combat illegal logging, reform trade policies, protect forested areas, and more.

What is an "Endangered Species"?

An endangered species is an animal or plant that's considered at risk of extinction. A species can be listed as endangered at the state, federal, and international level. On the federal level, the endangered species list is managed under the Endangered Species Act.

The Endangered Species Act (ESA) was enacted by Congress in 1973. Under the ESA, the federal government has the responsibility to protect endangered species (species that are likely to become extinct throughout all or a large portion of their range), threatened species (species that are likely to become endangered in the near future), and critical habitat (areas vital to the survival of endangered or threatened species).

The Endangered Species Act has lists of protected plant and animal species both nationally and worldwide. When a species is given ESA protection, it is said to be a "listed" species. Many additional species are evaluated for possible protection under the ESA, and they are called "candidate" species.

Why We Protect Them

The Endangered Species Act is very important because it saves our native fish, plants, and other wildlife from going extinct. Once gone, they're gone forever, and there's no going back. Losing even a single species can have disastrous impacts on the rest of the ecosystem, because the effects will be felt throughout the food chain. From providing cures to deadly diseases to maintaining natural ecosystems and improving overall quality of life, the benefits of preserving threatened and endangered species are invaluable.

How a Species Gets Listed

When the U.S. Fish & Wildlife Service or the National Marine Fisheries Service is investigating the health of a species, they look at scientific data collected by local, state, and national scientists. In order to be listed as a candidate, a species has to qualify for protected status under the Endangered Species Act. Whether or not a species is listed as endangered or threatened then depends on a number of factors, including the urgency and whether adequate protections exist through other means.

When deciding whether a species should be added to the Endangered Species List, the following criteria are evaluated:

Has a large percentage of the species' vital habitat been degraded or destroyed?

Has the species been over-consumed by commercial, recreational, scientific or educational uses?

Is the species threatened by disease or predation?

Do current regulations or legislation inadequately protect the species?

Are there other man-made factors threatening the long-term survival of the species?

If the answer to one or more of the above questions is yes, then the species can be listed under the Endangered Species Act.

Species Protections

Once a species becomes listed as "threatened" or "endangered," it receives special protections by the federal government. Animals are protected from "take" and being traded or sold. A listed plant is protected if on federal property or if federal actions are involved, such as the issuing of a federal permit on private land.

The term "take" is used in the Endangered Species Act to include "harass, harm, pursue, hunt, shoot, wound, kill trap, capture, or collect, or to attempt to engage in any such conduct." The law also protects against interfering in vital breeding and behavioral activities or degrading critical habitat.

The primary goal of the Endangered Species Act is to make species' populations healthy and vital so they can be delisted from the Endangered Species Act. Under the Endangered Species Act, the U.S. Fish & Wildlife Service oversees the listing and protection of all terrestrial animals and plants as well as freshwater fish. NOAA's National Marine Fisheries Service oversees marine fish and wildlife. The two organizations actively invest time and resources to help bring endangered or threatened species back from the brink of extinction.

As the world seeks to slow the pace of climate change, preserve wildlife, and support more than eight billion people, trees inevitably hold a major part of the answer. Yet the mass destruction of trees-deforestation-continues, sacrificing the long-term benefits of standing trees for short-term gain of fuel, and materials for manufacturing and construction.

We need trees for a variety of reasons, not least of which is that they absorb the carbon dioxide we exhale and the heat-trapping greenhouse gases that human activities emit. As those gases enter the atmosphere, global warming increases, a trend scientists now prefer to call climate change.

There is also the imminent danger of disease caused by deforestation. An estimated 60 percent of emerging infectious diseases come from animals, and a major cause of viruses' jump from wildlife to humans is habitat loss, often through deforestation.

But we can still save our forests. Aggressive efforts to rewild and reforest are already showing success. Tropical tree cover alone can provide 23 percent of the climate mitigation needed to meet goals set in the Paris Agreement in 2015, according to one estimate.

Causes of deforestation

Forests still cover about 30 percent of the world's land area, but they are disappearing at an alarming rate. Since 1990, the world has lost more than 420 million hectares or about a billion acres of forest, according to the Food and Agriculture Organization of the United Nations-mainly in Africa and South America. About 17 percent of the Amazonian rainforest has been destroyed over the past 50 years, and losses recently have been on the rise. The organization Amazon Conservation reports that destruction rose by 21 percent in 2020, a loss the size of Israel.

Farming, grazing of livestock, mining, and drilling combined account for more than half of all deforestation. Forestry practices, wildfires and, in small part, urbanization account for the rest. In Malaysia and Indonesia, forests are cut down to make way for producing palm oil, which can be found in everything from shampoo to saltine crackers. In the Amazon, cattle ranching and farms-particularly soy plantations-are key culprits.

Logging operations, which provide the world's wood and paper products, also fell countless trees each year. Loggers, some of them acting illegally, also build roads to access more and more remote forests-which leads to further deforestation. Forests are also cut as a result of growing urban sprawl as land is developed for homes.

Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and overgrazing, which may prevent the growth of young trees.

Why it matters

There are some 250 million people who live in forest and savannah areas and depend on them for subsistence and income-many of them among the world's rural poor.

Eighty percent of Earth's land animals and plants live in forests, and deforestation threatens species including the orangutan, Sumatran tiger, and many species of birds. Removing trees deprives the forest of portions of its canopy, which blocks the sun's rays during the day and retains heat at night. That disruption leads to more extreme temperature swings that can be harmful to plants and animals.

With wild habitats destroyed and human life ever expanding, the line between animal and human areas blurs, opening the door to zoonotic diseases. In 2014, for example, the Ebola virus killed over 11,000 people in West Africa after fruit bats transmitted the disease to a toddler who was playing near trees where bats were roosting.

(How deforestation is leading to more infectious diseases in humans.)

Some scientists believe there could be as many as 1.7 million currently "undiscovered" viruses in mammals and birds, of which up to 827,000 could have the ability to infect people, according to a 2018 study.

Deforestation's effects reach far beyond the people and animals where trees are cut. The South American rainforest, for example, influences regional and perhaps even global water cycles, and it's key to the water supply in Brazilian cities and neighboring countries. The Amazon actually helps furnish water to some of the soy farmers and beef ranchers who are clearing the forest. The loss of clean water and biodiversity from all forests could have many other effects we can't foresee, touching even your morning cup of coffee.

In terms of climate change, cutting trees both adds carbon dioxide to the air and removes the ability to absorb existing carbon dioxide. If tropical deforestation were a country, according to the World Resources Institute, it would rank third in carbon dioxide-equivalent emissions, behind China and the U.S.

What can be done

The numbers are grim, but many conservationists see reasons for hope. A movement is under way to preserve existing forest ecosystems and restore lost tree cover by first reforesting (replanting trees) and ultimately rewilding (a more comprehensive mission to restore entire ecosystems).

(Which nation could be the first to be rewilded?)

Organizations and activists are working to fight illegal mining and logging-National Geographic Explorer Topher White, for example, has come up with a way to use recycled cell phones to monitor for chainsaws. In Tanzania, the residents of Kokota have planted more than 2 million trees on their small island over a decade, aiming to repair previous damage. And in Brazil, conservationists are rallying in the face of ominous signals that the government may roll back forest protections.

(Which tree planting projects should you support?)

Stopping deforestation before it reaches a critical point will play a key role in avoiding the next zoonotic pandemic. A November 2022 study showed that when bats struggle to find suitable habitat, they travel closer to human communities where diseases are more likely to spillover. Inversely, when bats' native habitats were left intact, they stayed away from humans. This research is the first to show how we can predict and avoid spillovers through monitoring and maintaining wildlife habitats.

For consumers, it makes sense to examine the products and meats you buy, looking for sustainably produced sources when you can. Nonprofit groups such as the Forest Stewardship Council and the Rainforest Alliance certify products they consider sustainable, while the World Wildlife Fund has a palm oil scorecard for consumer brands.
