Around 20,000 of people took part in the 'Fridays for Future' demonstration, a global protest against climate change, in Berlin on Friday.

The majority of the demonstrators were students of different ages, accompanied by their teachers and parents.

They marched through the city centre, passing by governmental offices, including the Bundestag and the Federal Chancellery, carrying placards reading "There is no Planet B" and "Make the world cool again."

"It's just important that the world can continue to exist and people can keep living well. My kids also want to live in a world which is safe and where they can thrive," said Paul Brodowsky, a father participating in the demonstration.

Inspired by the Swedish student and environmental activist Greta Thunberg, the demonstration is part of a global movement taking place in around 1,700 cities in more than 100 countries, aimed at pushing world leaders into acting on climate change.
