Let's say you're not feeling very well. You feel shaky, achy and listless. You pad over to the medicine cabinet and get out the thermometer. Your temperature is 100 F (38.8 C). Since the average body's temperature is 98.6 F (37 C), you have a fever. Right? Considering the fact that Earth's temperature is estimated to have risen 1.2 to 1.4 F (0.7 to 0.8 C) over the last 100 years, you could say that Earth has a temperature, too [source: EPA]. It's not just the temperature of the planet that you need to worry about, however. All around the world, communities are finding they have severe problems with drought, air or water pollution, and garbage.
It's easy to get bystander syndrome about the environment and imagine someone else will "take care of it." But the truth of the matter is, if the citizens of Earth don't start taking care of the planet today, it might be too late to take care of it in the future. Imagine an old house in the country that's been abandoned by early pioneers. Without anyone to maintain the structure, it eventually collapses in on itself. If humans continue to neglect their home, millions of species could die, droughts can get worse and the Arctic Ocean could become iceless [source: An Inconvenient Truth].
You can do your part by volunteering to help the environment. Plenty of organizations exist that will allow you to help in big or small ways. And if you can't find one that seems like a good fit, you could start a group of your own. In this article, we'll take a look at both of these options. Read on to get green.
