Prince Harry throws his support behind Greta Thunberg

Earlier this week, 16-year-old environmental activist Greta Thunberg gave a killer speech at the Climate Action Summit, where she had to tell the grown-ups in the room that choosing economic growth over the fate of our planet is a tragic mistake, and that doing nothing is leading to the collapse of entire ecosystems and "the beginning of a mass extinction."So it shouldn't be surprising that Prince Harry, who is currently solo in Botswana, weighed in. For years, Harry — not to mention Prince William and their father, the royal OG of environmental activism, Prince Charles — have been preaching that climate change is a humanitarian issue, not a political one, and those who have the power to make a difference have taken far too long to wake up to the issues at hand and act on the harmful impact our ways of living are having on the world. Harry spoke up once more, backing Thunberg as he declared that the world is in a state of emergency, and we're losing the battle against climate change."The world's children are striking," said Archie's dad, after acknowledging the awesomeness of what Greta did this week. "There's an emergency, it's a race against time and one which we are losing – everyone knows it, there's no excuse for not knowing that. I think the most troubling part of it is I don't believe there is anyone in this world that can deny science, undeniable science and facts, science and facts has been around for the last 30, maybe 40 years." Harry stressed his absolute disbelief at the ignorance people have about cold, hard facts that can't be refuted. "Otherwise we live in a very troubling world."

Harry also spoke about how Botswana was a place for him to find a sense of peace after the death of his mother, Princess Diana, revealing that he's been going there for 15 years and that he found some of his closest friends over the years there."I came here in 1997 or 1998 straight after my mum died, so it was a nice place to get away from it all," he said. "I feel deeply connected to this place and to Africa."

In keeping with the environment talk, Harry joined schoolchildren for a tree planting event, where he earned a high five from one child. The royal also headed to a Sentabale project at Kasane Health Post, where he spoke with Let Youth Lead advocates and took part in an activity that boosts the self-confidence of children. The young people also had the chance to speak to Harry about their role in breaking the stigma that surrounds HIV and AIDS. Sentebale was co-founded by Harry in Lesotho in 2006 and aims to help young people with HIV.And even though Harry is on his own for the next few days, don't count out Meghan. She's still in Cape Town but left their son for a bit while she tended to business of her own. According to royal reporter Omid Scobie, Meg attended a private breakfast for Women in Public Service, and will continue to focus on female empowerment.YAAAAS. Meghan and Harry fighting for big causes. More, please. Of all of this.
