Warn the earth with love, without carbon dioxide!

I have alreadystarted to work for it. I travel by a bicycle and try not totravel by a personal vehicle, my car. I travel by buses for long tours. I switch off lights and electric appliances when not on use. I often get scolded by my father for doing such things. He says me that he is paying the bills and why should I care for all that. And I can't speak a lot in front of my father on this matter.
