super humans are predators that alter the natural balance of the earth because they kill too many animals and adult fish , scientists said today asking them to capture less and smaller creatures.
People tend to kill adult fish at a rate 14 times higher than marine predators , said study published in the journal Science.
In addition, human massacre largest land carnivores such as bears and lions at a rate nine times higher than the predators in the wild.
Based on a study on 2,125 predators worldwide , the scientists found that humans cause “extreme results that non-human predators rarely impose,” said Chris Darimont, coauthor of the study and professor of geography at the University of Victoria in British Columbia, Canada.
Between these extreme outcomes are extinctions, reducing both the number of fish and their size and disruptions in the food chain.
Such impacts are explained by the way unique in that hunt humans: with guns and using external energy sources such as gasoline, looking for the largest possible prey and often acting as suppliers of other mouths in faraway places
But. would be necessary to impose some changes, according to scientists, if humans want to continue encountering occasionally with animals such as rhinos, elephants and lions.
“We suggest a new and such transformative rather than face what should be sustainable exploitation “Darimont said.
For example, with regard to fishing, Darimont and study co-author Tom Reimchen urged that fishermen are focused on young and small fish.
Currently, humans tend to focus their fishing large specimens, because they provide more food and are easier to process than smaller ones.
But these fish are valuable when it comes to reproduction and their lives should be spared, so they can release more eggs throughout his adult life, the authors argued.
Reimchen research showed that birds and predatory fish killed mostly young forms of aquatic specimens.
