I guess I post these topics hoping to find someone who agrees with me, and I am then subsequently dismayed and frustrated that no-one has a viewpoint even remotely similar.
I dislike appealing to conspiracy theories, which is one reason I may come across as overbearing. At the end of the day, we all need to do our part and realise that we make up a bigger picture - it's no good not believing in something just because you think someone might be misguiding you. Believe in what seems right to you (particularly if the consequences of disbelief and inaction far outweigh the benefits of those things) until you can prove what you should believe.
With global warming - sure, it's in the media a lot at the moment and maybe there are groups with a vested interest in it. But even if this is the case, they are talking about the future of the planet and humanity, so it's pretty important stuff, and unlike some people in this thread I haven't given up on the idea that I can make a difference. Sure, my contribution may be small, but I can change the world for the better by considering the consequences of my actions and choices.
If we all did the same, I like to think that our collective action could dramatically improve the situation which we find ourselves in, and which we are putting future generations in.
Edit: Actually, thinking on it some more, I guess I am trying to change people's opinions to mine. But surely you can see why in this case. I'm advocating people change their lifestyles to be less consumptive and dependent on resources, and it is likely this will benefit the planet too. I personally have nothing to gain from it, and those I am trying to convince have little to lose by it, and yet our combined efforts will add up to a bigger whole. I don't understand why people don't see this. If you folk would like to offer some reasons why you personally are unwilling to believe the potential effects of global warming, and why you are unwilling to take steps to lead a less resource-dependent lifestyle, then I'm all ears.
