Trees are not just a feast for the eyes; they are the lungs of our planet1. These green expanses, called forests, are vital for our survival. They are the homes of countless species and the livelihoods of numerous communities. There are many large forests in the world, and collectively, they cover about 31% of the world’s land area.

Some of the largest forests include the Amazon Rainforest (the lungs of the Earth), the Congo Rainforest (Africa’s Green Heart), the Daintree (the world’s oldest rainforest), and the Sundarbans.

This article brings you a comprehensive list of the largest forests in the world that you should know about.
