Sara Underwood is back to preaching about the environment, and this time she forgot her clothing.

The former Playboy model posted a photo of herself wearing nothing but a thong while staring off into the distance at a mountain range. She captioned it, “It’s the only home we have, I wish we would start treating it as such.” (SLIDESHOW: 67 Times Abigail Ratchford Was Almost Naked)

I don’t know anything about the environment. I get paid to watch sports and stay woke about issues around the world. When it comes to the environment, I can go either way. (SLIDESHOW: 42 Times Arianny Celeste Went Topless On Instagram)

Having said that, I’ll get behind any cause that involves Underwood posting incredible wilderness photos. It’s hard to take a cause seriously when protesters chain themselves to trees and cranes. You throw a model into the mix and everything changes real fast. (SLIDESHOW: 26 Times Lindsey Pelas Went Topless)

Stripping down is certainly one way to get attention for your cause.
