The largest tropical rainforest in the world is the Amazon Rainforest. Spanning approximately 5.5 million square kilometers, it is primarily located in Brazil but also extends into Peru, Colombia, and several other South American countries. Renowned for its staggering biodiversity, the Amazon houses millions of species of plants, animals, and microorganisms, many of which are endemic. This rainforest plays a pivotal role in regulating the Earth’s climate by absorbing large amounts of carbon dioxide. Its preservation is crucial for both local communities and global environmental health.
