It's unbelievable but true. You can get a degree in Global Warming Studies at American Public University, online of course, as well as some other schools. The environmental trends and field is always changing, and you can get into the groove if you keep with the flow. Of course, it all could be nonsense, so let the buyer beware. There are some legit things like going down to the Florida Everglades and taking water samples. Keep that water and air clean. Work for the EPA, go on to a PhD, dig it.
