Did you know that Earth Day first began in 1970? Gaylord Nelson, a US Senator from Wisconsin, proposed Earth Day in order to bring environmental issues to the front of discussions and to give everyone a wake up call about the environment regarding air pollution most importantly. Dennis Hayes organized Earth Day that same year.
Each Earth Day millions of people get out and do something for the environment. Everyone can agree that the earth needs to be clean and protected. Communities across the world have big events planned. Click here to find one near you or check your local paper.

And if you are cleaning up a park, another landscape, the backyard, converting your house to be environmentally friendly, then you are being a preservationist at the same time. After all, historic preservation is the ultimate recycling. So, reduce-reuse-recycle in any way possible: water bottles, coffee travel mugs, packaging material, paper, and especially existing buildings!
