Don't be so down. We have solved the ozone hole problem - it will take years to heal, but we emit very little ozone destroying things anymore. Last year my local utility generated more power from wind than there was demand. People do care and are making change. Change is slow to come, and even after it happens takes a long time to make a difference, but there are signs of change and the cause is being taken care of.

Don't take that too far: there is a lot of work to do. However we have a good idea what that work is we just need to apply it.
