A GREAT useful thread indeed and we SHOULD ALL contribute to this.
Yes, by switching the lights off, the tv, ESPECIALLY the AC and I do understand it is summer but please if you feel so hot try taking a shower and not having the AC on all day.
I have a friend of mine who thinks 'Global Warming is fun'. I mean seriously if you don't mind that you DIE then that's your own choice BUT this environment is NOT YOURS alone because another billions share it with you. You wanna die? Jump from a cliff but don't threaten the life of billions of humans, animals and the next generation just because global warming is 'fun'.
And we ARE ALL responsible to this land we are living in. We should STOP destroying it and wasting water, electricity and other resources that God gave us. We should reserve, reduce and recycle.
