"Save the Earth" may be just a passing remark for those environmentally-unfriendly people. Having this "Live Earth - The concerts for a climate in crisis" may just be another passing remark on its own. However, there's still a small chance that they'll be able to 'hear' the Earth ... - - - ...

Let's just reduce, reuse and recycle as much as possible and whenever possible. It's quite far-fetched to say ban all cars, plastics, and other non-biodegradable stuffs. Use less of it.

Take a bike...
Bring your own bag...
make your own bottle...
gave away things instead of throwing away...(useable ones though)
stop poaching...
cut trees but plant more...
filter sewage...
neutralise chemicals.......
recycle instead of making it a refuse...(especially the papers from offices)
stop BLOODY SMOKING!...(or stop breathing for 24 hours!)
stop wastages...
....
....the list goes on....

Save the Earth, Save Yourself...
