As we (and celebs) do our part to celebrate our great planet today, getting informed (thanks, Netflix!) and shopping for a good cause, thousands more followed the lead of those that participated in the Women鈥檚 and Tax Day marches, joining their voices (and signs) together in unison to take a stand for another cause they strongly believe in: science.

Calling it 鈥渢he first step of a global movement to defend the vital role science plays in our health, safety, economies, and government,鈥 the group paid homage to Mother Nature (rather fitting for Earth Day, no?) and the perils science has proven she now faces, from climate change to deforestation. Check out 12 of the best signs we saw from the March for Science below.
