The plants release oxygen through the process of photosynthesis. The plants provide oxygen for animal respiration and also absorb carbon dioxide from the atmosphere. In this way plants help in maintaining the balance of oxygen and carbon dioxide in the atmosphere. Forests also influence climate, water cycle and air-quality. That is why forests are called green lungs.

Trees are called the lungs of the forest as they are the source of oxygen in the atmosphere. They while carrying out photosynthesis, utilize carbon dioxide and release oxygen, thus purifying the environment.

Some of the popular forests of India are:

Sunderbans

Gir forests

Corbett National Park

As trees are the main source of oxyzen and without trees no rainfall will occur.
