What can be done?

If we acknowledge that there are environmental problems, our first question is what can we do? Corporations and individuals can work toward acting responsibly, but as with most change, we'd rather that someone else go first. How long before the world's population reaches the tipping point and we all change our behavior? This means managing our lives as though the environment matters to us and to future generations. I think that ultimately, countries of the world need to ramp up their collaboration and put environmental policies on the table more frequently for discussion and action. We can shop responsibly and eat responsibly, and this does make a difference, but government and business needs to lead the way. Who is willing to take the risk and go first?
