The fishing techniques little respectful of the marine environment, such as trawling literally sweeps the sea, dragging all that live there, not only fish but plants, crustaceans, corals ...
The massive fishing of species that take years to procreate and therefore are sensitive and their number decreases by leaps and bounds. As the blue whale, 35 meters long and almost 200 tons, the white whale or the sperm whale.
But the main threat to marine species is the destruction of their environment , water pollution and use of the seabed as a landfill. An example of this disrespectful attitude towards the sea on our part is the island of trash floating adrift in the Atlantic, the size of the community of Extremadura.
Leaving aside without forgetting social criticism, let's focus on the species that inhabit our seas.
