ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photo by tasneemalsultan | Join photographer @filipe_deandrade today, Wednesday, June 17, at 11:15 a.m. EDT for a @natgeo Instagram Live as he travels to all seven continents to look at ecosystems worth conserving. Overlooking Wadi Hanifa, an area where Riyadh families go for picnics, I observe how a canyon that was once flowing with water is now desperate for rain. We've not yet seen a drought, but we do realize that our neighboring countries aren't all so lucky. From cloud seeding to irrigation, science and new inventions can only do so much. I hope that we can see how small steps can make big changes to save our planet. #riyadh #saudiarabia」6月17日 21時30分
