We have international laws against genocide, stating that you cannot systematically kill other human beings. But why not have a law against ecocide, meaning the severe destruction of our ecosystem? Bernhard Lenger launches a public awareness campaign, introducing ecocide as the fifth crime against peace. ‘This is Ecocide’ offers a physical and digital stage for speakers in favour of a new international law that will keep us from destroying the planet. As advocates like lawyer Polly Higgins climb the stage and upload their pleas, anyone who cares about the environment can join the thunderclap campaign. And don’t forget to upload evidence of crimes you may have witnessed; it might proof useful in future trials.
