The excess of global fishing has provoked the disappearance of more than 70% of specimens of some species of trees and shrubs, an “enormous increase” in the life of the oceans of unknown consequences, informing one of these markets.
The depletion of species like the martyr tiburon or the manta raya is inquisitive.
Others, like the oceanic tiboron, are on the verge of extinction. The fishes of the bush on its heights, very culinary appreciations. In 60 years, its population has grown to 98%.
“It’s a declining peor that of the majority of terrestrial mammalian terrestrial mammals, and appears to be equal to the blue ball”, a statement from AFP professor Nick Dulvy, of the Department of Biological Sciences of the Canadian University Simon Fraser.
Your team has collected and analyzed data that can elicit a reliable retrieval of 31 species of trees and shrubs.
Three quarters are in extinction.
“We believe that the situation was bad in many places, but because it was a result of various studies and information, it was difficult to have an idea of the global situation”, explains to the AFP scientist Nathan Pacoureau, who confirms the study published in Nature.
“We are going to discover (…) a huge extinction risk for the largest species in the largest and most endangered habitats on the planet, which we think are protected by human influenza”, said AFP Pacoureau, de la misma Canadian University.
“The dates reveal an enormous and creative increase in ocean life” denouncian the experts, that piden put coto to excess pesca.
For the 18 species of those with the most data available, the researchers calculated that their respective populations had a maximum of 70% in 1970.
The results have surpassed the experts, Pacoureau explains.
Además del tiburón oceanic, el common tiburón martillo and the giant martillo he llegado in a critical situation: his population has dropped more than 80%.
Los tiburones en las rayas son spesies especially vulnerabilities porque crecen lentamente y se reproducen poco.
According to the study, in recent years it has duplicated the use of words and speeches that capture the marine life without discrimination.
And the regional bodies that regulate the international fishing companies “did not write the protection of the tiburones and mantas rayas as a priority”, said Pacoureau.
Apply function protection rules, and an example is in the large white tiburine, a legendary species that has flown in American water, explains this expert.
