The environment is very very important of course but are we genuinely going to change? All we hear from adults is how we need to earn more money on a national level and all we hear from kids is what next best electronic thing they can own, and of course walking anywhere is out of the question.
Personally I would love to revert back to villages and eating locally grown food but that isn't possible without a population drop of biblical proportions, we are where we are and we're going to use resources until there's little or nowt left and that means even the people protesting today when the novelty of protest wears off and the new iphone comes out. It's admirable that they want to make a difference but just like Jonny Rotten they'll be selling the metaphorical butter when the moneyman comes calling.
