Ecosystems out of control: more and more poisonous spiders from southern Europe are invading hot Germany - with frightening speed.

Permanent drought in Central Europe and the resulting water shortage.

Climate change is hitting with tremendous force.

And messes up the whole structure.

For ecologist Johann Zaller from the University of Natural Resources and Life Sciences in Vienna, "all of this is no longer normal," as he tells

: "Evolution is not keeping up with the rapidly increasing temperatures." Consequence: animals come from the south, native species migrate north.

Including poisonous spiders, as reported

.

In Baden-Württemberg there have always been sightings of curled-hunting spiders.

The latest horror reports for every arachnophobic come from Pforzheim, Karlsruhe and Mannheim.

Originally at home in the Mediterranean region, the eight-legged friend has discovered the sunny south of Germany for itself - and will not leave it any more than the previously immigrated Nurse Dornfinger.

Incidentally, both spiders can penetrate human skin with their mandibles.

But that seems to be just the beginning.

Because much worse species are climatically ready to settle in Germany.

Global trade is the ticket of these animals.

For example, for the noble orb spider, which originally only occurs on Madeira and the Canary Islands.

already causing fear and terror

in Great Britain .

Not only due to the fact that it eats native bats, but rather can maim or even kill people.

The first noble orb spider was sighted in Germany in 2017 - given the combination of climate change and global trade, it will not remain the only one.

And then what researcher Dr.

Michel Dugon has already proclaimed for Ireland and England: "This species is here to stay and we must learn to deal with it." And the list of eight-legged poison bite candidates to come and stay is long.

Including the Southern Black Widow...

In addition to spiders of the genus

, which, like the brown violin spider, can decompose human tissue with their bite and whose worst representative is listed in the top 5 most dangerous spiders in the world, others will also come.

Eight-legged creatures that cause panic just by their appearance.

However, the wasp spiders, which are already native to Austria, are not dangerous to humans, just frightening.

However, they only provide sights that humans as the causer have to face.

Effects of climate change on poisonous spiders

A 2009 study shows that

a warmer Arctic, with an earlier onset of spring and longer summers, results in larger wolf spiders, according to

And they also produce more offspring.

At the same time, a study by Canadian researchers states that extreme weather conditions make spiders "more aggressive, more prolific and more resistant to longer journeys".
