Some tweaking to your lifestyle will help. But first you need to know your carbon footprint. Once you are aware about your impact on earth, you can calculate yourself into a green lifestyle.
You can also find more calculators posted by concerned being, Gil Friend, on Squidoo. You can add greening calculators you have discovered to Gil's list or you can discuss what you have been up to about carbon footprint on Wikipedia.
Now that you have heard, read and seen it; ACT!
