Deforestation means cutting down of trees on a large scale. Every day thousands of trees are being cut for any commercial purposes . Basically deforestation is done to fulfill the day to day need of people :-

To construct roads and bridges . To make flyovers. Generally trees are cut to make this .

To sell any property . Large plots selling required cutting down of trees.

For getting timber. Wood of trees can be used in many purpose like for making wooden product , furniture etc.

Deforestation has brutally effected on the environment . Trees are very important for us. The aur quality is decreasing day by day. Global warming is increasing . We have to face hot chilly summers. Shortage of oxygen . Soil erosion and many more.

So we need to stop this practice to save our future.
