Children in California are suing the US government over its failure to curb pollution, the latest in a series of legal actions by young people around the world worried about climate change.
The youngsters, aged between eight and 17, say the Environmental Protection Agency -- the federal regulator -- "intentionally allows life-threatening climate pollution to be emitted by the fossil fuel sources of greenhouse gases it regulates, harming children's health and welfare," according to Our Children's Trust, a non-profit law firm.
