Since arriving in the U.S. by boat to participate in the UN Climate Action Summit, 16-year-old Swedish activist Greta Thunberg has led crowds in both New York and Washington with a call for greater action against climate change.\nThunberg first captured the world\u2019s attention in August 2018 after she skipped school to sit on the steps of Swedish parliament, demanding that political leaders do more to address the environment. Since then, Thunberg has successfully spread her eco-activism message on social media and inspired young people all over the world to lead school strikes in protest.\n\u201cWe are the future. We are those who are going to have to adapt from this crisis,\u201d Thunberg told PBS NewsHour\u2019s William Brangham.\nMore highlights from the interview:\u00a0\n\nOn the urgency of climate change: \u201cMany people seem to have this double moral. They say one thing and then do another thing. They say that the climate crisis is very important and yet they do nothing about it,\u201d Thunberg said. \u201cIf I want to do something, then I go all in. I walk the walk. Walk the talk…I want to practice as I preach.\u201d\nOn the hope that political leaders will address climate change: \u201cI think people are just simply unaware of the situation and people are not feeling the urgency. I think that once we start treating this crisis as an emergency, people will be able to grasp the situation more.\u201d Thunberg added: \u201cAll of these climate movements that have played out during the last year, or years, is proof of that. I don\u2019t think anyone could have predicted the school strikes and the Fridays for Future movement to become so big and many other movements as well.\u201d\nOn the concern that small scale eco-activism will distract from broader policy changes: \u201cOf course, we focus on these isolated problems. We talk about, \u2018People need to eat less meat\u2019 …and then someone else says, \u2018No, it’s much more effective if everyone stops flying,\u2019 and so on,\u201d Thunberg said. \u201cWe need to focus on all of these things. Of course, individual change doesn’t make much difference in a holistic picture…but we need both systemic change and individual change.\u201d\nHow being on the autism spectrum influences her worldview: \u201cHumans are social animals. We follow the stream and since no one else is behaving like this is a crisis, we see that and we think, then I should probably behave as they do,\u201d Thunberg said. \u201cI’m on the autism spectrum. I don’t usually follow social coding and so therefore I go my own way.\u201d\nOn what Thunberg wants people to take away from her movement: \u201cEveryone can make a huge difference. We should not underestimate ourselves, because if lots of individuals go together then we can accomplish almost anything. So that’s what I want people to take away from this.\u201d\n\nThis story is part of Covering Climate Now, a global collaboration of more than 250 news outlets to strengthen coverage of the climate story.
