10 Largest Forests Found In Planet Earth
Forests are crucial for maintaining biodiversity as they provide habitats for a wide range of plant and animal species. They also contribute to climate regulation, carbon sequestration, soil protection, water cycle regulation, and the production of oxygen.
Forests can be classified into various types based on their geographical location, climate, and dominant tree species. Some common types include tropical rainforests, temperate forests, boreal forests, deciduous forests, and coniferous forests.
01. Amazon Rainforest:
The Amazon rainforest, often referred to as the "Lungs of the Earth," is the largest tropical rainforest on the planet. It is predominantly located in South America, covering a vast area across nine countries: Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana. The Amazon rainforest spans approximately 5.5 million square kilometers (2.1 million square miles), which is roughly the size of the contiguous United States. It is renowned for its exceptional biodiversity, with an estimated 390 billion individual trees representing over 16,000 species.
It is also home to millions of insect species, thousands of bird and fish species, and hundreds of mammal and reptile species. Some common trees found in this forest are Brazil Nut Tree, Kapok Tree, Rubber Tree, Mahogany, Cacao Tree, Andiroba Tree, Copaiba Tree, Samauma Tree, Brazilwood Tree, Strangler Fig etc. The forest is also a treasure trove of medicinal plants & traditional knowledge. Indigenous communities have used the forest's resources for generations to develop remedies for various ailments.
