It's not too late. If we each act now to curtail our personal carbon footprint the Earth has the potential to recover and support a human population of about 10 billion humans for thousands of years to come. Everyone must amediatley give up driving gasoline and diesel cars and trucks. Buy an electric car if you can, bike, walk or ride public transit. If you cook with gas start using electric appliances more; check out a microwave cookbook from the library.
If you heat with gas or God forbid diesel convert to electric as soon as possible. If we all do our part we can slow global warming enough to prevent "The End of the World"
