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. While they are too late for nature conservationists, Baltic Sea fishermen fear for their livelihoods. Many give up. Others have banded together to save themselves with canned fish.

Unintentionally online

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
Text: Horst Hamm
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«
Interview: Horst Hamm
Aquaculture is often associated with high levels of antibiotics and factory farming. Wrongly so, says marine biologist Tom Goldammer. Rather, breeding facilities are an alternative to overfishing the seas.

In many places the earth bears human footprints. Most of the time we don’t notice it, we don’t know it any other way. Satellite images enable a direct comparison between the past and the present – and thus a fascinating and frightening impression at the same time.

Tailwind as standard

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.

E-bikes are in great demand right now, and manufacturers can hardly keep up with deliveries. But how exactly is such a pedelec made? A company in Münsterland shows how production can be made as sustainable as possible. Above all, it’s the small ideas that make the difference.
