I agree with Renee to some extent. Environmental resources are not that important for private interests. There are no incentives for preserving the environment... as long as it does't seem to affect our own quality of life.
It does take a collective awareness to recognize that the pollution of the Earth will affect most of us in the long run, and that it is unethical to leave a garbage planet to the future generations.
Where I disagree with Renee is that we can't just wish to bring about a "revolutionnary change". Remember that if your ideas about the world are right, you don't need to use any forms of violence, just seize any opportunity to voice your concerns and convince more people that environmental damages are a major concerns.
By the way, there is nothing with making profits! As long as it's not harmful..
Off-course, I'm thinking about global warming as a priority.
