I may be prejudiced, but I seem to believe that China is a major polluter of the Earth with their heavy industry and emissions.

My eating no meat probably wouldn't remedy much.

And we never had any children, so can't be accused of contributing to the over-population of the planet.

My village has no bus, and is miles from anywhere. Our car is essential. (Too old to pedal a bike!)

So - not guilty M'Lud!
