I fully agree on promoting better care of our environment, but I was never someone sold to the whole doctrine of global warming. There are so many variables that can explain this. However, even without that in play, there are major problems associated with the activities that are generally thought to contribute to it anyway. For example, driving vehicles more often encourages obesity by promoting less activity. Obviously if you drive a car, it does not guarantee that you will be obese, but it does contribute to it. Dumping hazardous rate is bad for the environment for obvious reasons. The list goes on, but as I said, you don't necessarily have to believe in global warming to care about the environment.
