We all know that trees are very very useful to our very existence. Our food directly or indirectly is provided by them. Besides playing an important role to create our food and being the best air purifier, they are doing other important roles like: 1. They strengthen the land by preventing soil erotion. 2. They give us shadow to get relief from sun heat. 3. Their leaves or other parts are used as herbal remedies to treat some diseases. 4. They block free flow of air and prevent dusts freely coming to us. 5. Finally, during day time, they absorb carbon-di-oxide and release oxygen which is vital for our body thus acting as the best air purifiers in the world.
