A rainforest is an area covered with tall trees.

Rainforest is an area with abundant rainfall around tall trees, and the annual average temperature is rarely lower than 16 degrees. Rainforest has a great influence on the world environment, because it can reduce the temperature brought by the sun and adjust the climate. If there is no rain forest cover, these areas will absorb more heat from the atmosphere and raise the remaining world temperature. Losing the rainforest will also affect the wind and rainfall, which may lead to global natural disasters.

In the past 100 years, in order to find three main resources, human beings began to destroy the rain forest: land, grains, trees and other products used for paper making, and farms for raising animals. These behaviors have an impact on the whole environment. For example, a large amount of carbon dioxide in the air is produced by the burning of rainforests. People obviously need the vegetable oil we grow, but after that, we will lose more than we gain.

There are two main reasons for this. First, when people cut down trees, they can only use them for one or two years. Second, from now on, large-scale deforestation can obtain a batch of high-quality wood, but in the long run, it can actually reduce the world's wood supply.

Rainforest is always called the pharmacy of the earth. More than 25% of the medicinal materials we use today come from plants in the rainforest. However, less than 65,438+0% of rainforest plants have passed the medicinal value test, which seems to be our greatest opportunity to cure the world's rainforest diseases.
