Global Warming

I think global warming is definitely a concern; it might not be quite as big a deal as the fear-mongers make it out to be, but we are changing the environment in drastic ways and there are many simple things we can do to try and reverse the process. It's not that hard to reduce the CO2 emissions on a daily basis, but many people are still unwilling to admit that the environment is changing at all and therefore refuse to change even small habits that would make a big difference.
