Imagine a magical forest where the trees touch the sky. Due to enough rainfall, the trees grow huge and spread wide. Their tallest branches are so thick-leafed that they create a thick curtain. Even the wind does not find enough space to blow as it pleases. The climate is good for life forms of all kinds- from trees to animals, birds and insects. [2] These forests are called tropical rainforests. Most of them are located near the equator, in Asia, Africa and South America. The rainforest of the Amazon basin in South America is one of the lushest(茂盛的) rainforests in the world. You will find more varieties of trees or animal life here than anywhere else in the world. [3] The tropical rainforests are called the green lungs of the planet. They absorb carbon dioxide from around them to process their food and release oxygen into the air. They also contain the largest number of trees with medicinal value. [4] But now human beings are out to . Many companies all over the world, especially in the West, have been attacking these rainforests for a variety of reasons – some want to make profit by cutting down trees and selling timber(木材); others are trying to be the only ones to make profit out of medicinal plants. [5] To the outside world, the rainforest has always seemed a very dangerous place. Generations of films and literature have shown the people who live in the rainforests as dangerous and violent people who have a strange way of life. [6] But actually, these people have a better understanding of their relationship with their environment than modern man has. Greed for profit by destroying the planet’s resources is a unique quality of societies that have become modern and use technology.
