The movement is growing worldwide. In 2019, strikes have taken place across Europe, North America and Australia. Over 45,000 students protested on one day in Switzerland and Germany. Students have held banners reading, "Why learn without a future?" "If you do not act as adults, we will" and "Like the sea level, we rise." The first worldwide strike will take place on March 15. Many scientists, politicians and teachers congratulated the students for their activism. However, not everyone is on the students' side. Australia's leader called for "more learning in schools and less activism". A journalist in the U.K. wrote: "If children really must wag their fingers at older generations for some imaginary sin, I wish they'd do it at the weekend."
