The Amazon rainforest: an overview
The Amazon rainforest is the world’s largest tropical forest, covering an area of around 5.5 million square kilometers, which is 60% of the total area of the Brazilian Amazon (1). It is located in the countries of Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana (2). The forest is home to a wide range of plant and animal species, including many that are found nowhere else on Earth (3). It is also home to around 30 million people, including around 400 different indigenous tribes (4).
2. The Amazon rainforest and its importance
The Amazon rainforest is one of the most biodiverse places on Earth. It is thought to contain around 10% of all the world’s known species, including animals such as jaguars, sloths and monkeys, and plants such as palms, Orchids and bromeliads (5). This diversity is important for two main reasons. Firstly, it helps to maintain the balance of the Earth’s ecosystems by providing a variety of different plants and animals that can interact with each other. Secondly, it provides humans with a range of resources that we rely on for our survival, such as food, medicine and timber (6).
2. 2. Amazonian indigenous people
As well as being home to a huge variety of plants and animals, the Amazon rainforest is also home to around 30 million people, including around 400 different indigenous tribes (7). These tribes have lived in the forest for thousands of years and have developed a deep knowledge of its plants and animals (8). They also play an important role in its conservation, as they are often the best placed to spot early signs of environmental problems and take action to prevent them (9).
3. Causes of the Amazon rainforest destruction
3.1 Climate change
Climate change is one of the main causes of the Amazon rainforest destruction. Rising temperatures and changes in rainfall patterns are making the forest drier and increasing the risk of wildfires (10). These changes are also making it harder for trees to grow and causing many species of plants and animals to die or move to other areas (11).
3. 2 Deforestation
Deforestation is another major cause of the Amazon rainforest destruction. Every year, around 17% of the forest is cleared for agriculture, livestock grazing or other development projects (12). This deforestation not only destroys vital habitat for plants and animals, but also releases large amounts of carbon dioxide into the atmosphere, further exacerbating climate change (13). In addition, deforestation can also lead to soil erosion and flooding, as well as putting pressure on local communities who rely on the forest for their livelihoods (14).
3.3 Infrastructure development Infrastructure development is another significant cause of deforestation in the Amazon rainforest. The construction of roads and railways often leads to trees being cleared from large areas of land (15). This clearing can make it easier for loggers and developers to access previously untouched parts of the forest, leading to even more deforestation (16). In addition, infrastructure projects can also have a negative impact on local communities who may be forced to relocate or give up their traditional way of life (17).
3.4 Industrial development Industrial development is also contributing to the destruction of the Amazon rainforest. The mining, logging and oil industries are all damaging the forest, both through direct deforestation and also by polluting the air and water (18). In addition, the construction of hydroelectric dams is often leading to the displacement of indigenous communities and the flooding of large areas of forest (19).
4. Impacts of the Amazon rainforest destruction
The destruction of the Amazon rainforest is having a significant impact on the environment and on local communities.
4. 1 Environmental impacts
The loss of trees and other vegetation in the Amazon rainforest is leading to a decrease in the amount of carbon dioxide that is being absorbed from the atmosphere. This is exacerbating climate change and making it harder for other plants and animals to survive in the Forest (20). In addition, deforestation is also causing soil erosion, which can lead to flooding and make it difficult for plants to grow (21). Deforestation can also have an impact on local water supplies, as it can change the way that water flows through the landscape (22).
4. 2 Social impacts
The destruction of the Amazon rainforest is also having a significant social impact on local communities. Indigenous peoples who have lived in the forest for generations are being forced to relocate or give up their traditional way of life (23). This can lead to poverty and social problems such as alcoholism, domestic violence and suicide (24). In addition, local communities who rely on the forest for their livelihoods are often left without food or income when their homes are destroyed or their land is flooded (25).
The Amazon rainforest is one of the most important places on Earth. It is home to a huge variety of plants and animals, as well as around 30 million people. However, it is under threat from a range of different issues, including climate change, deforestation and industrial development. The destruction of the Amazon rainforest would have a devastating impact on the environment and on local communities. It is therefore essential that we take action to protect this vital ecosystem.
