Photo: Gisele Bundchen/Facebook
The supermodel did her best Mother Earth impression by posing naked and wrapping herself up in ivy, amongst a forest of plants and trees (she obviously wasn't willing to go without footwear). She posted the photo, along with the message, "Today is the Earth Day! Our health depends on the health of our planet. Let's take care of our beautiful home".
If this photo doesn't get the world's attention, we don't know what will.
