Another Friday, another strike. Young people across the UK took to the streets on Friday to demand action to fix the climate change crisis, according to the Guardian.

Protestors in London were spotted carrying a green banner asking for a Green New Deal, an American proposal to transform the country's energy infrastructure and reduce carbon emissions.

This student-led protest comes in the wake of a government report showing that the UK will miss its 2025 and 2030 emissions targets.

"This is my future not yours, that’s why I care ... We’re striking today on our school holiday, which shows that we’re willing to take time off our holiday to protest because it’s such an important cause," Aida Freij, 13, told the Guardian.

Young people are taking part in the #YouthStrike4Climate across the UK & the world today.

This demonstration is part of an ongoing campaign called #FridaysForFuture, which was started by Nobel Peace Prize nominee Greta Thunberg.

The climate activist began the movement in August 2018, when she skipped school for three weeks and sat on the steps of the Swedish parliament building. She's continued protesting and leading strikes since September.

On March 15, Thunberg and kids from around the world went on strike, carrying powerful signs that called for action on climate change. It goes to show, young people really are the future.
