Tropical- rain forests are considered to be the lungs of the Earth due to their role in the carbon-oxygen cycle. The rain forests take in carbon dioxide and release oxygen into the Earth hence, providing the Earth with an abundance of oxygen. The working of these tropical rain forests is just like the working of our lungs, lungs remove carbon dioxide from the body and supply oxygen.
