Deforestation

Sometimes, people cut down many trees.

They clear the land to make farms. They also use land for ranches. This can happen for coffee or palm oil.

Losing trees can hurt the Earth. It can take homes from plants and animals. It can also change the air.

Many trees are lost each minute. This can cause big fires.

We can learn how to help our forests.

Deforestation is when people remove trees from a forest. They often clear the land for other uses.

Most forest loss comes from agriculture, which is farming. People make farms for coffee, rubber, and palm oil. Some use the land for cattle ranches. Other causes include mining and building cities.

Losing forests can change our world. It destroys habitats, which are homes for plants and animals. This can lead to extinction. This means a species might disappear forever. Forests also help the air. They take in carbon dioxide. Without them, climate change can happen faster.

Forest loss is a big issue in the tropics. These are warm, wet areas near the equator. In 2019, nearly a third of tree loss was in these forests. These areas are very important for biodiversity. Biodiversity means having many different kinds of life.

Deforestation is the removal of trees from a forest. This happens when land is changed to a different use.

People often turn forest land into farms or ranches. Some areas are cleared to build cities. Forests cover about 31% of Earth's land surface today. This is one-third less than before agriculture expanded. About half of that loss happened in the last century.

Most deforestation happens because of agriculture. In 2012, more than 80% of forest loss was for farming.

Forests are turned into plantations for coffee, rubber, and palm oil. Livestock grazing also drives this change. Other causes include the wood industry, mining, and urbanization. Climate change can also cause more wildfires. These fires lead to even more tree loss.

Losing forests causes many problems for our planet. It destroys habitats, which are homes for living things. This leads to a loss of biodiversity. Biodiversity is the variety of different plants and animals. Deforestation can cause animals and plants to go extinct. It also changes local climates and affects indigenous people.

Forests are very important for the air we breathe. They help by taking in carbon dioxide from the atmosphere. This process is called carbon sequestration. It helps to slow down climate change. When forests are gone, this help is reduced. Since 1990, about 420 million hectares of forest have been lost. Between 2015 and 2020, the rate was 10 million hectares per year.

We can see how our choices affect the world. For example, the things we buy can drive forest loss. Patterns of trade and consumption are linked to deforestation. In G7 countries, people cause an average loss of 3.9 trees per person each year. This is often linked to imports like coffee.

Even though the rate of loss has slowed, it is still a big job to protect our forests.

Deforestation is the permanent removal or destruction of forest cover from a specific area. This process occurs when land is converted to a non-forest use.

Common conversions include turning forest land into farms, cattle ranches, or urban spaces for cities. Currently, forests cover approximately 31% of the Earth's land surface. This represents a significant decline from previous levels. Before the massive expansion of global agriculture, forest cover was much higher. In fact, current levels are about one-third less than they were before that expansion.

The drivers of deforestation are diverse, but agriculture is the primary cause. In 2012, more than 80% of all deforestation was attributed to agricultural activities. Forests are frequently cleared to create large plantations for products like coffee, palm oil, and rubber. Livestock grazing is another major driver of land conversion. Beyond farming, other industries contribute to tree loss. The wood industry, known as logging, plays a significant role. Mining operations and urbanization also drive forest clearance. Additionally, climate change increases the risk of wildfires, which act as another cause of forest loss.

Deforestation triggers a chain of environmental consequences. The most immediate effect is habitat destruction. When trees are removed, the homes of countless species vanish. This leads directly to biodiversity loss, which is the decrease in the variety of life. Such loss can result in the extinction of both plants and animals. Deforestation also causes changes to local climates. It can lead to soil erosion and desertification, where land becomes dry and unproductive. Furthermore, the displacement of indigenous people who live within these forests is a serious social consequence.

A critical scientific impact involves the carbon cycle. Forests play a vital role in carbon sequestration. This is the process where trees take in carbon dioxide from the atmosphere. By capturing this gas, forests help mitigate the effects of climate change. When forests are destroyed, this capacity for carbon uptake is greatly reduced. This creates a link between deforestation and the risks posed to global food systems. As climate change impacts agriculture, the loss of forest carbon storage makes the system less resilient.

Historical data shows a massive shift in global forest cover. Since 1990, an estimated 420 million hectares of forest have been lost. This loss occurred through conversion to other land uses. The total area of primary forest—mature, undisturbed rainforest—has decreased by over 80 million hectares since 1990.

While the rate of deforestation has actually decreased over the last three decades, the impact remains high. For example, between 2015 and 2020, the rate was approximately 10 million hectares per year. This is down from a rate of 16 million hectares per year in the 1990s. On average, roughly 2,400 trees are cut down every single minute.

Different regions experience these changes in unique ways. In the period between 2010 and 2020, Africa had the largest annual rate of net forest loss at 3.9 million hectares. South America followed with a loss of 2.6 million hectares per year. Interestingly, the rate of net loss in South America declined significantly in the most recent decade compared to the previous one. In contrast, Asia saw the highest net gain of forest area during the 2010–2020 period. Tropical primary forests are especially vulnerable. In 2019, nearly one-third of all tree cover loss, or 3.8 million hectares, happened in these humid tropical areas.

Global consumption patterns also drive these environmental shifts. Deforestation is often linked to international trade and the demand for specific commodities. For instance, consumption patterns in G7 countries are estimated to cause an average loss of 3.9 trees per person each year. This loss is often tied to imported goods like coffee.

Even if deforestation happens in one country, it is often driven by the needs of consumers in another. This connects local land use to global economic systems. Understanding these complex links is essential for addressing forest loss on a worldwide scale.
