Save Our Planet - 101!

Let us put our thoughts together to come up with ideas to save our planet, in our own little way!
Here are some thoughts..
1) Don't print out directions while going somewhere ( for those of us who still survive without GPS),take a minute to write it down at the back on a used envelope!
2) Avoid kitchen towels,use cloth ones, and yes, they do wash clean.
3) Avoid leaving taps running when we dont need the water.
4) Turn off lights when we dont need it,saves the planet and lowers electricity bill.
5) use post-it paper on both sides,just fold over the sticky part when one side is used, the other side makes good scratch paper.
6) before hitting the print button at office, think about it for a second"Do I really need this printed out?",if yes, atleast use double sided print outs!!
7) Walk short distances instead of driving, spare the air, and also,save on the gas bill.
8) PLEASE don't say," it does not matter what I do, I cannot save the planet on my own!", after all, little drops of water make a mighty ocean,isnt it?
We need to make this list grow, please let the comments flow..
