“I want you to act as if the house was on fire—because it is.” Greta Thunberg’s urgent message about climate change inspired millions of young people to raise their voices and lead strikes around the world—and that’s why, we’ve named this activist and vegan PETA’s Youth Role Model of the Year. At only 16 years old, Greta has inspired a worldwide movement to combat the climate crisis. Leading young people in the global Youth Climate Strike movement, her fearlessness and commitment have inspired millions around the world to reduce their carbon footprint and lessen their environmental impact. She has led by example—making choices that have the biggest impact on the planet—most importantly by eating vegan. Globally, animal agriculture is responsible for more greenhouse gases than all the world’s transportation systems combined. Whether promoting being vegan to millions of her followers on Instagram (and meeting Esther the Wonder Pig!) or to millions of viewers on The Ellen DeGeneres Show, Greta truly walks the walk and shows that you can help fight climate change every single day by leaving animals off your plate. You inspire us, Greta.
