I'm not convinced that we (in the form of industry and vehicle pollution) are the sole cause of "global warming". I'm also not convinced it's the governments fault as much as it is human nature, industry and capitalism run a muck. Otherwise, you're absolutely right.
We are pretty reckless in our approach to life and living, and unlike the philosophies of the east, which center more around surpressing ones ego, we work hard to build ourselves up to incredible heights with unrealistic expectations.
Our "wants" are slowly being replaced with "needs" ..and like any Philosophy 101 student knows, if you always want what you don't have, you'll never be happy. It's no wonder people and the western world today in general are increasingly frustrated, anxious, depressed, overweight and in general .. unhealthy, this despite enjoying a quality of life never imagined.
