Global marine fish stocks have almost given out. This has happened because of constant overfishing and environmental degradation especially in places of spawning.
Although it is a big problem, it is not irreversible. World renowned scientists believe that its solution lies in the consolidation of fish farms and a temporary ban on any commercial fishing. Warships of developed countries patrol the world's oceans to prevent industrial-scale fishing.
People have witnessed the emergence of a series of "gaps" in the food chain, which has resulted in the rapid decline in the population of marine mammals and birds. Some of them are dying out, many are migrating to the Arctic and Antarctic regions, as well as in the equatorial regions, where they still can find food.
The illegal network of fish suppliers and fisheries is rapidly growing. The police and armed forces of seafaring nations are making concerted efforts to fight against poachers and illegal sellers.
