Tropical rainforests cover about 6% of the Earth's surface and include areas like the Amazon, Central America, and Equatorial Africa. Deforestation of these areas has many harmful consequences and is primarily driven by slash-and-burn agriculture, plantation farming, commercial logging, cattle ranching, and fuel wood collection. Potential solutions include providing financial incentives to preserve forests, promoting sustainable farming practices, reducing demand for products causing deforestation, and replanting selected trees.
