The event in Warsaw, Poland's biggest, was organized by the Youth Climate Strike movement and saw crowds of Polish youths carrying banners with slogans such as “No time to skimp a dime, the forests are burning,” and “There are no families, animals or holidays on a dead planet.”
Thousands of cities around the world took part in the protest on Friday, Polish state news agency PAP reported.
The global youth climate strikes were sparked by teenage activist Greta Thunberg, who last year rose to fame after she picketed in front of the Swedish parliament every Friday to protest government inaction on climate change.
At the strike, the Youth Climate Strike presented six demands, which included calling on the government to acknowledge there is a climate disaster by officially introducing a state of climate crisis, as well as formulating a climate policy based on current scientific research presented in a report by the Intergovernmental Panel on Climate Change (IPPC), which is a body established by the United Nations.
On September 21-23, the United Nations Climate Change Summit is set to take place in New York, PAP reported.
