Prince Charles has been vocal about climate change over the years, and he understands that it takes a long time for things to get moving.
The 72-year-old was asked if he sympathized with Greta Thunberg, who is a young activist.
"Of course I do, yes," he replied. "All these young people feel nothing is ever happening so of course they're going to get frustrated. I totally understand because nobody would listen, and they see their future being totally destroyed."
"All these young feeling nothing is ever happening, so of course they're going to get frustrated. But it isn't helpful, I don't think, to do it in a way that alienates people," Charles continued. "So I totally understand the frustration, the difficulty is how do you direct that frustration in a way that is more constructive rather than destructive. The point is that people should really notice how despairing so many young people are."
The royal understands that it's difficult to change our lifestyle, but he said little steps like not eating meat could really help the planet.
"If more people did that it would reduce a lot of the pressure on the environment," he said, adding that he doesn't eat meat and fish two days each week.
"No one person can solve the problem," he said. "It's a pinprick."
Prince Charles, Queen Elizabeth, Camilla, Duchess of Cornwall, Kate Middleton and Prince William will attend the U.N. Climate Change Conference COP26 during the first week of November in Scotland.
He hopes that everyone can come together to find a solution otherwise there will be consequences. "I mean it'll be catastrophic. It is already beginning to be catastrophic because nothing in nature can survive the stress that is created by these extremes of weather," he shared.
