Pledge to leave an environmental footprint that´s as small as possible, and please ask your friends

Please try whatever you can to keep your environmental footrpint as small as possible, you can easily do this by walking, using your bicycle, the bus or the train instead of a car or even SUV that needs a lot of fuel, but also by not using a plane if you don´t really have to, for business for example, that´s an exception, I´d say. But every plane that flies some 1.000 miles far causes a CO2 emmission that´s bigger than someone´d do it if he used his car and drove 50 or more miles every day, that´s unnecessary and only kills our environment and many wild animals´ habitats, I use to say: if God had wanted us humans to fly he´d have given us wings....

And please ask your friends & family to try their best to keep their environmental footprint as small as possible, too!!!
