Taking responsibility for how we think about the world, and our place in it, allows for positive change. I really think its not about allotting blame, it is about accepting that we are a part of the problem of pollution, and doing something about it, just as you are doing Snooz.
The multinational corporations, that are the big polluters, did not get there by themselves. People gave them support and power, and then we continue to support them by consuming their products. This, however, is something we can change, we can do this in our daily lives, and we can encourage others to make changes that benefit the planet and our fellow beings.
