Overexploitation of species, objects of fishery
To the moment, a dozen of species that were most popular fishes during the hundreds of years became rare and endangered species. Like god-fish, in many areas herring, wild salmon and few more species now have almost no economic value in the North Atlantic seas. Even if there are still some quotas for fishery of these species, the volume of quotas decreased annually.
Not only fishes, but also invertebrates and macro algae are under pressure of human beings. In many countries inhabitants collect invertebrates along the tidal. In vicinities of cities and settlements the tidal communities could be really "eaten away".
