Re: Electric planes?
This one is fine, and will last for ages.
Look, there are some very good reasons for using less, and reusing and recycling what we have. However, in the developed world, we have the safest, healthiest environment in history, and lots of disposable income (on average). Things my parents (born in the 1930s) could not have imagined for the first 40 years of their lives have become commonplace - all of it made possible by the use of fossil fuels. People who want radical green policies want us to move back to pre-industrial levels, without hope of ever getting out, and they want to do it without engaging in proper, democratic, debate.
The developing world will be left forever behind if they adopt green policies, so the "enlightened" developed countries are enforcing it on them, and the complaining that they never make anything of themselves.
When you can talk in terms of the moral correctness of maintaining (for the developed world) and improving (for the developing world) the standard of living through efficient reuse and recycling, we'll have common ground. Talk to me about "only one planet" and I'll not hear a word you are saying.
