This 24 February 2019 video says about itself:
Some 35,000 Belgian school children skipped classes on Thursday to protest global warming and pollution in one of Brussels’ biggest ever student protests, vowing to miss school once a week until the Belgian government takes action.
Students banging drums and carrying signs decrying global warming gathered around the European Parliament, in what Brussels police said was an unprecedented turnout for a student protest in the Belgian capital, also home to European Union institutions.
Translated from Belgian daily De Morgen today:
Swedish climate activist Greta Thunberg (16) will come along to Brussels demonstration next week [Thursday 21 February]
The Swedish climate activist Greta Thunberg (16), who became famous worldwide for striking week after week against climate change, will come to the Brussels climate march next week to join the protest. Anuna De Wever of Youth for Climate recently announced this.
Next week the climate action will not take place in Namur, as communicated first, but again in Brussels. The reason for this is a special guest: Greta Thunberg, the Swedish teenager who is the source of inspiration for the Belgian climate truants, will come to the demonstration.
“Of course we are very satisfied with her arrival”, says Anuna De Wever. “She ultimately lies at the basis of the movement.” With the arrival of Thunberg, Youth for Climate hopes for a big turnout.
Greta Thunberg became famous all over the world for skipping school to go to the parliament building in Stockholm every Friday to demand a better climate policy. She inspired thousands of students from all over the world to do the same, including the Belgian girls Kyra Gantois and Anuna De Wever, who have been mobilizing multitudes of students for climate marches in Brussels for 6 weeks in a row.
Thunberg was previously invited to the World Economic Forum where she addressed the world leaders and called for a more ambitious climate policy. “I want you to feel the fear I feel every day, and to take action, as if something is on fire somewhere, because that is the case,” said Thunberg. “We still have a small chance to stop greenhouse gas emissions and save a lot of people on our planet from a lot of suffering.”
The Swedish girl then also on Twitter mentioned the success of an earlier edition of “truancy for the climate” in Brussels. “A Belgian journalist just told me that 35,000 students play truant in Brussels. Heroes!” she said. Now she will join such a climate demonstration herself.
