According to numerous scientists, 30 % of the oceans and, if possible, 30 % of the land area must be protected by 2030. This is the only way to preserve at least some of the biodiversity on this planet. Otherwise, the overexploitation will continue: most fishing grounds are already overfished, and many species are almost extinct. Around 64 % of the sea surface is in international waters. It is precisely in these areas where it is crucial to put large zones under protection. However, apart from the Antarctic, there are hardly any areas where this is legally possible. In our latest episode, we asked our Councillor Anna Oposa and our senior advisor Dr. Ralf Sonntag how we can push national governments to advance ocean protection and better educate young people in marine conservation.
