We live on the very beautiful planet, World which has very clean and attractive nature full of Verdancy. I think nature is our best friend because it gives us water to drink, pure air to breathe, food to eat, land to stay, animals, plants for our other uses, etc for our development.
So we should fully enjoy the nature without brunt its ecological balance. We should care our nature, make it peaceful, keep it clean and prevent it from the destruction so that we can enjoy our nature forever. Nature is a very expensive gift given by the God to us to enjoy but not to damage.
