AID RAIN FOREST

Rainforests are forests characterized by high rainfall, with annual rainfall in the case of tropical rainforests between 250 and 450 centimetres (98 and 177 in) and definitions varying by region for temperate rainforests. The monsoon trough alternatively known as the intertropical convergence zone plays a significant role in creating the climatic conditions necessary for the Earth’s tropical rainforests. Around 40% to 75% of all biotic species are indigenous to the rainforests. There may be many millions of species of plants insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the jewels of the Earth and the world’s largest pharmacy because over one quarter of natural medicines has been discovered there.

Rainforests are also responsible for 28% of the world’s oxygen turnover sometimes misnamed oxygen production processing it through photosynthesis from carbon dioxide and consuming it through respiration. The undergrowth in some areas of a rainforest can be restricted by poor penetration of sunlight to ground level. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs and small trees, called a jungle. The term jungle is also sometimes applied to tropical rainforests generally. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation the resulting habitat loss and pollution of the atmosphere.

IMPORTANCE OF RAINFORESTS

The main benefit of rainforests is that they supply much of the earth’s oxygen. They absorb carbon dioxide produced by manmade activities and produce oxygen on which all humans and animals survive. They also contain millions of species of exotic plants and animals. Rainforest supplies many things essential for the survival of human and other living beings. Importance of rainforests can be derived from the items that they supply. Some of these are listed below:

  • Natural medicines
  • Oxygen production
  • Sugar
  • Spices such as coconut, vanilla, turmeric, ginger etc.
  • Rubber
  • Bamboo
  • Pineapples
  • Chocolates that come from cocoa which grow on trees in rainforests

A rainforest needs an adequate amount of rainfall and sunlight to grow tall and large. Areas near equator don’t have any seasons because neither it tilts towards or away from the sun. It remains warm (16 degrees Celsius) and receives more than 1000 centimeters of rainfall throughout the year. They cover only about 6% of the earth’s surface and more than 30 million species of plants and animals live in tropical rainforests. Many exotic species of plants and animals grow in rainforest.
