As a human,part of life in a place called 'earth',did we ever think of what we did to our earth??

LET me TELL what we did~we burn and cut the plants that make our earth warmer and warmer by each second....
Is that what we supposed to contribute for this lovely place called 'EARTH'? think twice, HUMAN~
HUMAN, wake up now! there is no time to waste..if you think you can sit at home enjoying the air conditioner without not caring the outside world that is getting warmer and warmer...you are deadly wrong!
PLEDGE for our mother earth:
I, will try my best to not harm the mother earth, give my best effort to conserve the mother earth, give love for the living plant, reduce carbon trace of mine, giving advice to my friends to also conserve the mother earth.
