World population: Now we are 8 billion – How many people can the Earth handle?

Will it be in Tokyo, Delhi, or Cairo? Will it be somewhere among the evergreen forests of Central Africa, or will it be in a U.S. state in the Midwest? Or even in Austria? Today, in any case, the birth of the eighth billionth earth citizen is expected: 8,000,000,000 people – thousand times as many as in Austria, will thus live on our fragile globe, according to the calculations of the United Nations.

HIGH CONCENTRATIONS: Arctic littered with plastic like inhabited regions

According to a recent study, the Arctic is now similarly littered with plastic as densely populated regions. High concentrations of microplastics are found in the water, in rivers, on the seafloor, on uninhabited beaches, and even in ice and snow, report researchers at the Alfred Wegener Institute (AWI) in Bremerhaven. This has consequences for the living creatures there, but possibly also for the climate. The Arctic is perceived as a largely untouched wilderness – but that no longer corresponds to reality, says AWI biologist Melanie Bergmann, co-author of the analysis…

It is true that mosquitoes like certain people better than others. Researchers have repeatedly proven this in controlled experiments, says Swedish mosquito researcher Marcus Stensmyr from Lund University in an interview with #Faktenfuchs. But which people does it hit particularly often? Not all mosquitoes bite peopleFirst of all, it’s essential to know that only a handful of mosquito species bite humans. And even among the human-biting varieties, only the females bite. This is because they need human blood – or, more precisely, specific proteins in it – to produce eggs.…

That’s why we often wake up shortly before our alarm clock

Have you ever been able to observe the following phenomenon? The alarm clock is set in the morning – after all, you can’t miss the plane or the important meeting the next day under any circumstances.
