I've found some alternative sources to fossil fuels as Nuclear power ( Uggglh!), solar ower, wind power, tidal power or geothermal power. Solar power is the best suited to the country I live in. Reycling is important to save resources and to preserve our under siege environment.
I've found a Grenpeace's campaign against Japan' whaling programme in South Ocean Whale Sanctuary.
I'm a member of Fundació Mona, which is working for primate welfare and to end their explotation in captivity. It's a nice environmental organization example, I think.
