Earth Day is probably the greenest of all green holidays, if not the most popular.

But did you know there are more than 50 green holidays?

Earth Day is considered somewhat of a “Hallmark Holiday” for most environmentalists. We’re all about living our lives as sustainably as possible—some more than others—on a daily basis. It’s not about perfection, though… it’s about doing our best with what we’ve got. Take me, for example: It makes no sense for me to buy a hybrid car when I already own a somewhat decent 2003 VW station wagon with less than 80,000 miles. If we could afford solar panels, they’d be on my roof right now. I do, however, buy organic food and limit my family’s meat consumption whenever possible. You’ll find absolutely no plastic baggies or storage containers in my house, but you’ll see the environmental-disaster-waiting-to-happen keurig single-cup coffee machine on my kitchen counter (a gift to my son purchased by my hubby, despite my pleading against it). Fortunately, they drink the coffee only on weekends.

I’m happy there’s an Earth Day—it’s important to remind the world that the Earth is worth celebrating and that there are things we can do to help make the world safer for future generations. What better day than Earth Day to kick off a new eco-resolution, whether it’s switching to eco-friendly home cleaning products and organic food or adding solar panels to your roof. Or maybe you’re ready to go meatless on Mondays! Or use reusable shopping bags every time you go shopping.

Earth Day isn’t the only environmental holiday…

Before you dig in to all of them, I hope you’ll listen to the special Earth Day edition of the Green Divas Radio Show, featuring environmental superhero Ed Begley Jr.!

Here’s a list of over 50 green holidays you could celebrate virtually every day.
