Earth will experience a mass extinction of flora and fauna in 80 years

A new study warns that planet Earth will face a Mass destruction By the year 2100 it could be destroyed even more A quarter of the world’s biodiversity.

The analysis is published on a special site Scientific advances, The 2022 United Nations Conference on Biodiversity (COP15) will be held in Montreal, Canada.

In this research, Australian and European scientists have created a ‘virtual earth’ to better map the global destruction caused by climate change. Based on the results, They predict a 10 percent loss of all plant and animal species by 2050, rising to 27 percent by the end of the century.

Is this the end of the earth? A planet rushes to its doom against its host star

The study was led by European Commission scientist Giovanni Strona and Professor Corey Bradshaw from Flinders University in Adelaide, Australia.

The planet, in its sixth extinction event: a threat to species

Academics say the planet has already entered its sixth mass extinction event, driven by human activity and climate change.

Scientists blame overexploitation of resources, land-use change, pollution, climate change and “biological invasions”.

According to the Red List of the International Union for Conservation of Nature, More than 42,100 species are threatened with extinction.

“Children living to the age of 70 today can expect to see the extinction of thousands of plant and animal species, from tiny orchids and tiny insects to iconic animals such as elephants and koalas,” said Professor Bradshaw, who was sent. Mail Online.

Using the technology, scientists created a model of the world with more than 15,000 “food webs” to predict the fate of interconnected species.

In this regard, the tool can “map extinctions in all regions of the Earth” and predict a bleak future for global biodiversity, confirming that the world is in the midst of its sixth mass extinction event.

Co-extinctions: What they are and how they affect biodiversity loss

Co-extinctions refer to species becoming extinct because others – depending on them – disappear due to climate change or changes in their habitat. “A predatory species loses its prey to climate change,” Bradshaw explained.

“The loss of a prey species is a primary extinction because it directly succumbs to a disturbance, but without anything to eat, its predator will perish,” he added.

He also provided examples of, for example, a parasite losing its hosts due to deforestation or a flower plant losing its pollinators due to global warming. “Each race is in some way dependent on others”, said.

“Each species depends on the others in some way,” the study authors note. Photo: Pixabay

They say extinction is now recognized as a major contributor to global biodiversity loss, strongly amplifying the effect of primary factors such as climate change. That’s why research shows species are connected by “who eats who.”

For his part, he Science Strona explained the model: “We essentially created a virtual world from scratch and mapped the fate of thousands of species around the world to determine the probability of real-world tipping points,” he said.

“We can then assess adaptation to different climate scenarios and correlate them with other factors to predict the pattern of extinction,” he added.
