STOP POISONING ME!
A world full cars is a world full of Carbon Dioxide. It's time for change.
There's probably 6.1 billion of tons of CO2 in the air at this very moment, that's equals to 2.1 millions elephants!
Let's be realistic. We can't get rid of all CO2 but what we can do is produce less. Why not ride your bike to work or to school. Why not tax those who produce CO2 in great amounts? This will decrease it not eliminated. Its better than releasing CO2 in vast amounts.
It's your choice of what kind of world you want to live in. I made my choice. Whats your choice?
