21 children and young people are suing the US government over climate change.

The video discusses the Juliana vs. United States case, where a group of young plaintiffs, led by Kelsey Juliana, is suing the US government for failing to address climate change. The case questions whether there is a constitutional right to a safe climate. It highlights the impact of climate change on youth and the environment, and the government's long-standing knowledge of the issue. The video also covers the legal proceedings and the hope for a landmark decision, akin to the end of segregation, to force government action. It concludes with the rise of youth activism for climate justice across the US.
