June 11, 2021 THE WASHINGTON POST – Many people are learning about climate change thanks to Greta Thunberg. The Swedish teenager started Fridays for Future in 2018 by skipping school once a week to call people’s attention to our warming planet. In this case, skipping school is called a “strike”. Her actions launched a movement of school strikes around the world. Lots of other kids – even those who are much younger – have figured out ways to help save the Earth. They’ve gotten involved in environmental causes close to their hearts. Some of them are inspired by the ‘30 by 30’ initiative: Fifty countries, including the United States (US), have promised to protect 30 per cent of Earth’s land and waters by 2030.
