Wow. This is not the content I expected when I opened this thread. However, as has been acknowledged in some posts, above, climate change (or whatever you want to call it) is entirely driven by population growth. it doesn't matter whether you think the problem is more flying, more driving, more manufacturing, more meat eating, less forests etc etc this is all driven by population growth. So, only as and when ER, the Greens, the Sainted Emma T etc come out and campaign for people to have less children will I start to take them seriously and I will not, under any circumstances, be lectured on climate change by anyone with more than two children.
