No offence intended, but that seems to me like defeatism, and precisely what no-one must do. While there's any chance to fix this problem, IMHO everyone should do the little they can. e:g, never get in an aeroplane again and tell people why. Buy local food / grow your own, refuse to purchase products shipped from far when there are local alternatives. And tell people why. Ensure any investments you have are not in fossil fuel companies. And tell people why. Drive far less, or not at all. Red meat far less, or not at all. And tell people why! History teaches us there were plenty of totally unacceptable things that have happened and eventually people against the odds stopped this . To pluck a random example, there was a time in the UK for example when women weren't allowed to vote. That got fixed. ;) There must have been some very strong vested interests at the time that didn't want women to vote but it got overturned by strength of public feeling. I really hope this year's weather in N America will be a wake-up call.
