Heike Lotze contributed to this new publication by the Heinrich Böll Stiftung in Germany, that illustrates the important roles played by the ocean and its ecosystems for people around the world. It aims to give current insight on the state of – and threats to – the seas. Covering more than two-thirds of our planet’s surface, the ocean provides us with food, energy, minerals, transportation routes and is crucial for our climate and weather systems. But due to human impacts, the future of these ecosystem services is threatened. Also available in German.
