Biodiversity refers to the variety of organisms present on the planet Earth. The largest rainforest, Amazon forest, located in Brazil, South America, has the greatest biodiversity on the Earth.
It is composed of nearly 40000 species of plants, 3000 of fishes, 1300 of birds, 427 of mammals, 427 of amphibians, 378 of reptiles and more than 125000 of invertebrates. More than two million insect species are yet to be discovered from here.
South Africa is considered to be the third most bio-diverse country in the world for housing over 95,000 known species of organisms.
India contributes to 8.1% of the global biodiversity and is considered to be one of the 12 mega-biodiversity countries of the world.
Russia shows high levels of biodiversity too but is not considered a mega biodiversity centre unlike South America, South Africa and India.
America is the continent that has the most countries rich in biodiversity: Brazil, Colombia, Ecuador, Mexico, Peru, Venezuela (S. America) and the United States (N. America). For its part, in Asia, the countries with the greatest bio-diversity are China, Indonesia, India, Philippines and Malaysia. In Africa, Madagascar, Democratic Republic of Congo and South Africa are rich in biodiversity. And, lastly, Oceana has Australia and Papua New Guinea. These countries, together are home to more than 70% of the planet's bio-diversity! and their territory is only 10% of the earth's surface.
