A forest is a purifier of air and water. Trees present in forests act as green filters. They release oxygen as a product of photosynthesis. In this way, they purify air by increasing the amount of oxygen in atmosphere. They also helps in removing harmful particles and pollutants.

Due to activity rain, soil gets erode. The eroded soil enters into water bodies and pollutes it. Trees slow down the activity of rain and rain water gets absorbed by the soil. In this way, forest help in purifying water.
