Greta Thunberg launched a world movement
Former US President Barack Obama supported, on Saturday in Berlin, the mobilization of young people, every Friday, against lack of action on climate change.
"The sooner they start, the better",said Obama in a debate with a group of young people in the German capital.
The ex-president gave his support to the protests of the adolescents, initiated by the 16-yeqr-old Swedish Greta Thunberg, every Friday to demand intensification of the fight against climate change.
"A lot of these people cannot vote, they're still too young to vote, but they know what's going on," Obama added.
