In Thomas friedman's new book Hot, flat and crowded
there is a chapter in which he talks about how China/India are fast becoming like America in terms of consumption. Many people in China and India now want to buy the same Ipod, eat the same burger, travel to far off places, just as Americans have been doing all these years. (You can't really blame anyone for wanting that). But because of their individual populations this is going to destroy all natural resources in this world. Soon.. (I believe there should be some articles on the net about China's role in Africa) That is why you see everyone now talking about cutting emissions/green tech and all that stuff.
But what can anyone do about this? This world is not friendly towards people who want to do things differently. Everyone around me was complaining when I spent 8 months last year without a cell phone. And before that I didn't have a car for 8 months and was using public transport. Not once did anyone say: "Hey man thats cool! One less car on the road". And can you really say I don't want to travel during holidays because I want to save the environment?? Obviously, I didn't have the environment in mind when I said/did all the above. I was just being myself: lazy ass guy. But I don't think people's reaction would be any different if I actually wanted to save the environment.
So, I think we have a conflict here. You aspire for a life that allows you to buy stuff: fancy electronics,cars,homes; gives you the means to travel to places, so that you can build new experiences. But the very fact that everyone around you wants the same, and there are too many of "you", just doesn't augur well for the environment.
