Tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity. [21] Other parameters that affect tropical rainforests are carbon dioxide concentrations, solar radiation, and nitrogen availability.
Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. [ 2 ] Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation , the resulting habitat loss and pollution of the atmosphere .
A tropical rainforest climate or equatorial climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator. There are some other areas at higher latitudes, such as the coast of southeast Florida, United States, and Okinawa, Japan that fall into the tropical rainforest climate category.
About half of the world's tropical rainforests are in the South American countries of Brazil and Peru. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rainforests.
Borneo rainforest. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. [1] There is no single scheme that defines what a forest is, in tropical regions or elsewhere.
Some leaves in tropical forests from South America to South East Asia are getting so hot they may no longer be able to photosynthesize, with big potential consequences for the world’s forests ...
Threats to the rainforests include destruction and fragmentation of forests by commercial logging, oil palm plantations, and mining. The bushmeat trade and poaching is depleting the rainforests of wildlife. [2] With annual forest loss of 0.3% during the 2000s, [5] the region had the lowest deforestation rate of any major tropical forest zone. [6]
The tropical rainforest climate differs from other subtypes of tropical climates as it has more kinds of trees due to its precipitation. [12] The large number of trees contribute back to the humidity of the climate because of the transpiration, which is the process of water evaporated from the surface of living plants to the atmosphere.
