Tropical rain forests are usually located very close to the equator. They get anywhere from 70 to 400 inches of rain per year, but generally average 70-80 inches per year. In addition to heavy rainfall, they are also characterized by extremely warm temperatures that on average can exceed 64 degrees year round. One of the biggest reasons that tropical rain forests are so critical to our ecosystem is because of their vast amount of biodiversity; 40-75% of the world's biotic species are endemic to tropical rain forests, and about 50% of all living plants and animals are found in these environments. However, deforestation is severely impacting these forests; it has been estimated that in 50 years 25% or more of Earth's species could go extinct.
