The tropical rain forests are the places on the land that have by far the highest biodiversity, both in plant and animal life. Because they have such a high biodiversity, and the vegetation is evergreen and constantly active, they have a huge effect on the global biosphere. They're the ones that increase the numbers and diversity on the planet, but also that huge biodiversity, especially in the plant life, contributes to higher levels of oxygen into the atmosphere, and that is very beneficial for all of the biodiversity on the planet. It is not coincidence that the Amazon rain forest, the largest in the present, is nicknamed ''the lungs of the Earth''.
