People are experiencing the greatest animals in the world at the brink of extinction, and our main driving force is our insatiable meat appetite.
This is a terrible warning, and it came from the first analysis that people were looking for on the megafauna of the world
Combining more than 300 abnormally large vertebrates, including polar bears, blue whales, hippies, saltwater crocodiles, ostriches, the findings suggest that our common environment is troublesome
. falling numbers and over 150 are pushed out of the shadow of extinction
"Our results show that we are going to disappear megafauna," says William Ripple, Oregon State Ecology expert. University.
"70 percent in the future Will suffer further depopulation and 60 percent. Species can disappear or very rarely. ”
If people decide to continue this path, loss can threaten the planet. we know that. Biodiversity is basically a diversity of life that retains all of the world's ecosystems, but people are now facing an environmental crisis after thousands of years of uncontrolled action.
Imagine this is a Jenga game. The more units we remove, the more unstable the whole system, only with the threat of collapse
"Biodiversity conservation is crucial for the structure and functions of the ecosystem, but it is detrimental to population decline and geographical loss, which is about one fifth of the world's vertebrate species at risk of extinction ", Writes the authors.
The problem has long evolved
Since late pleistocene, more than a hundred thousand years ago, people have caused havoc due to global biodiversity, following a large vertebrate sending a large backbone to the abyss of extinction. , over the last 65 million years
But over the last 500 years, everything has started to accelerate, and scientists are worried. Today, each megafauna class is the highest risk for human hunting
In fact, 98 percent of the people are hunting. All threatening megafauna species are threatened by "direct harvesting of meat or parts of the body"
These great creatures not only have more meat and possibly more glory, they are also less
That is why large vertebrate animals remain at an exceptional risk of extinction, not only from hunting. , but also due to the deterioration of their habits
"Megafauna species are more threatening and represent a higher percentage of declining populations than all other vertebrate species," explains Ripple.
So, while megafauna has a small collective biomass, their constant loss is already changing the structure and function of our ecosystems, still discovering
For the past 250 years, we know that nine megafauna species have completely disappeared or disappeared outdoors. Animals at greatest risk are animals on the ground
This is undoubtedly because people can make them easier. For example, 2012 Two major turtle species and two deer species disappeared.
Marine creatures are a bit better. Only 27 percent Species are seen as threats, but there are also more than two dozen of which we simply do not know.
Boni fish, such as sharks, rollers and rays, are at the top of the list. more than any other marine group.
Ultimately, however, only those great creatures who have reached the land and the sea most often saw the worst results. Of all the mega amphibians, only one species remains on the earth
with a weight of 40 kilograms and up to 1.8 meters, the Chinese giant salamander ( Andrias davidianus ) is sometimes referred to as a living fossil. a few surviving family members who grew up to $ 170 million years
It is believed to be a delicacy in Asia, so now it is very dangerous and scientists say it's just a matter of time before it also disappears
Fears that more beings are directed in the same way, the authors insist that "our increased abilities as hunters" would be
Otherwise we could eat the last of our planet megafauna.
"Preserving the remaining megafauna will be difficult and complicated," says Ripple.
"It will be against economic arguments as well as cultural and social barriers. But if we do not discuss, criticize or correct our behavior, our increased abilities, like hunters, can encourage us to consume many of the last megafauna of the Earth. "
