In the past century, we have lost 90% of the large fish in our ocean. This Earth Day, we face a tremendous challenge, and a new opportunity. We know that our survival depends on the natural world, and it has never been more imperiled by human exploitation. But we also know that when protected, natural ecosystems can restore themselves. That’s why we’ve partnered with the Wyss Campaign for Nature to raise awareness about the urgent need to protect nature, and enable people and wildlife to thrive together. Check out @InsideNatGeo to learn more about how the National Geographic Society is working to support the protection of 30 percent of the planet by 2030, a key milestone toward protecting half of our Earth. #EarthDay #CampaignforNature」4月22日 13時32分
