Biologist from the University of Queensland (Australia) Leslie Roberson published an article from which it follows that humanity systematically uses about a hundred species of endangered marine animals for food. And these are only those cases that we know about. How many rare marine species we literally eat right now cannot be counted.
In many countries, there is already a shortage of some species of commercial fish, which was in abundance at the end of the last century. Administrative and legal measures do not make sense, because the catch from the unknown region is repeatedly overloaded, processed and eventually ends up in stores with the vague label “sea fish”. No bans and fines will help here, we all need to radically revise our diet and simply give up fish. No demand - no catch and no damage to the ecosystem.
But how, then, can we solve the problem of providing food for billions of people? Scientists believe we need to turn to the only sustainable renewable food source in the sea (besides algae): jellyfish. In recent years, there have been too many of them, so eating jellyfish, in addition to satisfying hunger, will bring great benefits to the people living by the sea and the ocean itself. It was jellyfish that made fisheries ineffective in a number of countries that historically depend heavily on it - for example, in Japan.
A logical question: how to convince millions of people to eat jellyfish? In fact, this is a matter of habit and tradition, because the same shark fins, although they are considered a delicacy, are practically inedible without the necessary sauces and knowledge of recipes. People eat a lot of weird things that only get flavor and value when cooked right, and jellyfish are no exception. In China, they have been cooked for 1700 years, and three years ago, jellyfish chips were introduced in Denmark. This is just a matter of technique and a competent PR campaign - but it must be carried out within the framework of the entire planet.
