Forests can purify the air and regulate the climate, and tropical rain forests play a vital role in the environment.
The tropical rain forest is mainly distributed on the north and south sides of the equator. It is hot and humid all year round with lush plants. It can absorb a large amount of carbon dioxide in the air and release a large amount of oxygen, which has a great impact on the global climate. Therefore, the tropical rain forest is also known as the "lung of the earth". In addition, tropical rain forests are extremely rich in biological species, including more than 45000 species of higher plants alone. Rich plant species provide food and habitat for a variety of animals, so it has also become the most abundant area of animal species on earth. In the hot summer, the forest is refreshing and pleasant. Tropical rain forest has high biodiversity and rich biological resources.
