Well, it's Earth Day. Or, as people in 2015 say, "It's #EarthDay2015, y'all!" Is that right? Not sure. Anyway, there are a number of celebrities celebrating the wonderful date that has us all remember to be kind to Mother Earth ... for one day, at least. To join in on the fun, we at MStars News decided to unveil to our readers a handful of celebrity Instagram accounts – anyone from Leonardo DiCaprio to Entourage star Adrian Grenier – that are enlightening us all with facts, methods and tips on how to continue saving our lovely (in some places) planet.

Let's run down a list of 5 celebrities who are celebrating Earth Day 2015.

AMY SMART: A well-known environmentalist, actress Amy Smart is teaching us all how to make non-toxic soap. And we are forever (?) grateful.
