Explanation

If you're a true environmentalist, you care deeply enough about the natural world to make protecting it a real priority. You may even have made it your life's work. These days, there's no shortage of work for the world's environmentalists. What with climate change, oil spills, gas drilling, deforestation, and species decline (just to name a few), there's almost no time to breathe. Show me an environmentalist with nothing to do, and I'll show you someone who isn't paying attention. Environmentalists — people who work to protect the environment — often work hand in hand with conservationists, whose job is to protect and maintain as much of the natural world as possible.
