She created the innovative Take Extinction Off Your Plate campaign, and her work has been featured in Scientific American, NPR, The Guardian, The Washington Post, and more.

When she's not advocating for animals or the future of our planet, she can usually be found exploring nature or working on her next book in the company of assorted rescued dogs and cats.
