Tropical forests are an ecosystem that occurs near the equator all around the earth.
Due to tropical forests never freezing, about 12 hours of sunlight per day, and having massive rainfall, tropical forests have a high number of different types of organisms. Tropical forests contain 50% of the types of organisms found on earth in only 6% of the earth's landmass.
Tropical forests store carbon emissions to reduce the effects of global warming. Much of the world's oxygen is produced by tropical forests and many important medications were discovered due to the abundance of medicinal plant species.
The consistent moisture produced by tropical forests helps keep rainfall consistent. The deforestation of tropical forests contribute to drought.
