Most people have heard of greenhouse gases and the way they are changing the climate of the planet. They also know that our motor cars produce carbon dioxide which is the main greenhouse gas.

This short quiz of 6 questions will show you that reducing your meat consumption can have more impact on your contribution to greenhouse gas emissions than reducing your motor car usage or using energy saving light globes. Of course, doing all 3 is even better!
