      During the COVID-19 pandemic, the world's most famous teenage environmental activist has mostly stepped aside from the spotlight.

      In an interview aired today, Greta Thunberg told the BBC that the lockdown offered her an opportunity to relax and reflect on things.

      She talked about the Black Lives Matter movement—and what it represents to her.

      "It is always the fight for justice," Thunberg said. |It feels like we have passed some kind of social tipping point where people are starting to realize that we cannot keep looking way from these things. We cannot keep sweeping these things under the carpet, these injustices."

      She also spoke bluntly about the cynicism of world leaders. 

      "The level of knowledge and understanding even among people in power is very, very low, much lower than you would think," she told the BBC.

      Thunberg did not mention Prime Minister Justin Trudeau, whom she met last September.

      Trudeau did not travel to New York to hear Thunberg's famous "How Dare You?" speech at the United Nations Climate Action Summit in September but met her when she visited Montreal later that month.

      "The eyes of all future generations are upon you," she told Climate Action Summit delegates last year. "And if you choose to fail us, I say we will never forgive you."
