Forest are referred to an area with high density of trees.
Forest may vary significantly in size and different classification according to their composition and density. They include herbs, shrubs, and trees.
About 9.4 percent of Earth’s surface is covered with the forest so are central to all human life because they provide a diverse range of resource.
They purify water and minimize natural hazards such as floods. They contain biodiversity and produce oxygen for them.
They may be divided into the tropical rainforest, temperate forest, coniferous forests, mountain forest and plantation forests.
According to area and density here is the top 15 largest forest in the world.
1) AMAZON FOREST
Amazon forest is located in Brazil. It is RAINFOREST. Its area is 5,500,000 KM square. The majority of it is contained within Brazil. It compresses most of largest and most biodiversity of tropical rainforest with an estimated of 390 billions of trees of 16000 species.
This rainforest has been in existence for at least 55 million years ago. There is evidence that there is a large number of modification in Amazon rainforest over the last 21000 years.
Human inhabitants first settled in Amazon region at least 11200 years ago due to which there is an alteration in forest vegetation and biodiversity.
Some five million people lived in the Amazon region between dense coastal settlement but now population reduced to two million.
It is believed that the civilization was decreased due to the spread of diseases like smallpox. Deforestation is also going on due to which there is a threat to biodiversity species. Amazon forest has much biodiversity.
One out of ten known species in the world lives in the Amazon rainforest he constitutes the largest collection of living plants, animals and birds. Animals in the rainforest a present in large number.
