Answer 2

Answer:

Forest are called (LUNGS) of the earth because it produces around $20$ percent of the planet's oxygen.

Explanation:

Tropical rainforests are frequently referred to be the "lungs of the planet" because they typically breathe oxygen in and carbon dioxide out. Because of how much carbon dioxide they collect from the atmosphere, forests are referred to as the earth's lungs. Protecting those lungs is essential if we are to maintain plant biodiversity and stop global warming because they are effective. Because they constitute a source of oxygen for the atmosphere, forests are referred to as the "lungs of nature."

• The photosynthesis mechanism allows plants to release oxygen. Animals' need for oxygen to breathe is assisted by plants.
• They also keep the atmosphere's ratio of oxygen to carbon dioxide in check. For this reason, forests are referred to as "green lungs."
