Will opponents to Heathrow stop flying?

There's nothing that irritates me more than those who oppose airport expansion yet carry on flying. Regardless of whether there is another runway at Heathrow or not, the expansion pales into insignificance when you consider that China plans to open 97 regional airports over the next 10 years. Why should Westerners who have benefited from decades of mass air travel deny those in the rest of the world from enjoying the same benefits?
