The herring in the Baltic Sea is doing badly. Climate change and overfishing are endangering stocks, which is why the EU is imposing increasingly strict fishing quotas.

Millions of seabirds and dolphins, turtles and small fish end up as bycatch on fishing boats and in trawl nets every year. This annoys the fishermen and harms the environment. But developing new methods for targeted fishing is a challenge.

This is how good aquaculture works

Enjoy fish without a guilty conscience? Not so easy, because even aquaculture often pollutes nature. A new facility for pike-perch breeding in Mecklenburg-Western Pomerania could show how things can be improved. Foreseeable damage to nature: almost zero.

»High stocking densities are just a cliché«

More than seven million bikes with electric motors are driving on German roads and forest paths. If you move around with zero local emissions, you protect the environment. However, high prices, a lack of infrastructure and supply bottlenecks are still slowing down the triumph of pedelecs.
