Alice Springs (AP) - Demonstrations in Australia have started the global strike for more climate protection. Tens of thousands of students stayed away from the classroom in protest at inadequate policies against climate change. Big rallies are planned in big cities like Sydney and Melbourne. In the city of Alice Springs in the center of Australia, hundreds of people demonstratively lay down on the ground and killed themselves. Worldwide, the youth movement Fridays for Future awaits several hundred thousand participants. In Germany alone, more than 500 demos are planned.
