LONDON (AP) — Teenage climate change activist Greta Thunberg has accused adults of stealing young people’s future as she met senior British politicians at Parliament.

The 16-year-old Swede, who has sparked a global wave of youth environment protests, met Labour Party leader Jeremy Corbyn and other lawmakers Tuesday.

She told a meeting in the House of Commons that “we probably don’t even have a future any more. That future has been sold so that a small number of people can make unimaginable amounts of money.”

Environment Secretary Michael Gove also met Thunberg and acknowledged: “We have not done nearly enough.”

As Thunberg spoke, environmental protesters demonstrated outside Parliament, with some hanging hammocks in trees.

The group Extinction Rebellion has brought parts of London to a standstill over the past week by blocking roads.
