热带雨林被破坏
亚马孙平原的原始森林自16世纪就被人类开发。到1970年,为了解决东北地区的贫困问题,巴西总统下令开发亚马孙平原。这一决策使该地区每年约有8万平方公里的原始森林遭到破坏,1969年~1975年,巴西中西部和亚马孙地区的森林被毁掉了11万多平方公里,巴西的森林面积同400年前相比,整整减少了一半。热带雨林的减少不仅意味着森林资源的减少,而且意味着全球范围内的环境恶化。因为森林具有涵养水源、调节气候、消减污染及保持生物多样性的功能。亚马孙平原的热带雨林与世界气候及一切生物的健康关系密切,一旦遭到大肆破坏,将影响全世界人们的生存。
Destruction of tropical rainforests
The original forests of the Amazon Plain have been developed by humans since the 16th century. By 1970, in order to solve the poverty problem in the northeast, the Brazilian president ordered the development of the Amazon Plain. This decision caused about 80,000 square kilometers of original forests in the region to be destroyed every year. From 1969 to 1975, more than 110,000 square kilometers of forests in central and western Brazil and the Amazon region were destroyed. Compared with 400 years ago, the forest area in Brazil has been reduced by half. The reduction of tropical rainforests not only means a reduction in forest resources, but also means environmental deterioration on a global scale. Because forests have the functions of conserving water sources, regulating climate, reducing pollution and maintaining biodiversity. The tropical rainforests of the Amazon Plain are closely related to the world's climate and the health of all living things. Once they are severely destroyed, it will affect the survival of people all over the world.
The Amazon rainforest is vital to the health of the world and all living things that live in it. This forest has a great impact on the world's climate. The forest can absorb carbon dioxide. The presence of this gas in large quantities causes the earth to warm up, and even melts the polar ice caps, causing floods. Trees also produce oxygen, which is necessary for the lives of humans and all animals. The oxygen produced by the Amazon rainforest accounts for 1/3 of the total oxygen in the world, and is known as the "lungs of the earth."
The irrational development of the Amazon rainforest has caused environmental problems: the destruction of animals and plants, the reduction of biodiversity; soil erosion, increased sand content in rivers; frequent rainstorms and droughts; land desertification and a series of other environmental problems.
The irrational development of the Amazon rainforest has caused environmental problems such as soil erosion, increased sand content in rivers; the destruction of precious wild animals, and reduced biodiversity. "The sharp increase in sandstorms and the serious harm caused by wind and sand" and "the triggering of global population movement and the sharp increase in the population in the area" are not environmental problems caused by the irrational development of the Amazon rainforest.
The Amazon Plain in Brazil is the largest plain in the world. It is home to the world's largest tropical rainforest. Through photosynthesis, it continuously absorbs carbon dioxide and replenishes oxygen to the atmosphere. It is known as the "lungs of the earth". Due to its indiscriminate logging, its area is shrinking, which has attracted strong attention from the international community.
The main environmental problem in the Amazon River Basin is the indiscriminate logging of tropical rainforests, which has caused environmental problems such as reduced forest area, increased soil erosion, reduced animal and plant resources, and ecological deterioration.
