The real issue is resources not climate change. We are using up the planets resources at such a rate that they are not being renewed naturally.
In Britain we throw away 33% of all food bought, yes 1 in every 3 bags of food bought WTF!! There are billions of people going hungry every night and the British throw something because of a "sell by" or "best before" date which means bugger all, its only the "Use by" they should pay attention to and even that is arbitrary.
The only thing thrown in our house is veg peelings, bones, egg shells etc and that goes in the composter.
CO2 emissions and Climate change are debatable and many people disagree with it, but it's easily quantifiable and hence taxable, even if the cause of extra CO2 may or may not be wrong. If the argument was over resources then nobody can disagree and we may actually make some real differences to peoples lives.
Blimey that was a rant.
