We are because of nature. We are surviving on precious oxygen in the air, surviving on water, having uncountable food that we want to enjoy & to have good for our health, getting incomparable light from Sun, enjoy soothing moonlight, enjoy luxurious lifestyle because of valuable minerals & metals. The golden era keep going on freely and never asks for anything. It's we to value it so that our coming generations should also be thankful to the Nature...it's golden era.
