Sure, but we have limited ability to force other nations to comply. And given how the US leads the way in over-consumption and carbon footprint per capita, getting our own house in order is a good place to start. It's the one thing we have complete control over fixing. As for your last paragraph, I don't entire disagree... But on the other hand, I feel people wash their hands of the problem because it's "too big to fix myself" and continue leading a life of over-consumption because "it doesn't matter anyway". Both are wrong-headed. Decisions need to be made at both the personal and national level to change things. Americans used 50 billion water bottles last year. Now, I don't rant and rave about water bottles most of the time because it's such an obvious thing to cut out of our lives (most of the time) that it should have been done voluntarily years ago. And that's just one thing. One thing. You don't believe 10 trillion water bottles has an impact on the world over a 20 year period? Simply cutting that consumption in half results in 5 trillion fewer water bottles being manufactured, discarded, and left god only knows where to (never) decompose.
