Plants are the Gift of God. They can be refered to 'Resource of Oxygen'. Without plants no man will be able to live. Man need oxygen for breathing which is released by plants and they need CO2 to live which are released by human beings.
So Man and plants are interdependant. Deforestation, filling of paddy fields will lead to Global warming. So it is more preferable that to prevent those type of activities. These activities are done for the well being of lesser time which would affect the earth for the whole period. So it is ideal not to cut plants,trees etc. Planting more trees and plants are more preferable which would lead to a moderate climate,well being etc. People these days are not aware about this.
So they cut trees etc. for their own welfare. Grow more plants so that we can get back the beauty of earth and achieve the longevity of human beings and earth.
