What happens if Thanos really is going to erase half life from the face of the Earth?

Unless you’ve been hiding under a rock for the last year, you should know that the ending of “the Avengers: infinity War” was pretty bleak. Let’s refresh your memory: Thanos managed to collect all the Infinity Stones, complete gold-plated glove of fate and snap my fingers, destroying half of all life in the universe. And if you thought that the “big wash” will cause ecological disaster, scientists who have a lot of thinking on this subject, I believe that life itself is quite resistant to the plans of the Mad Titan.

However, some species to the brink of extinction, and in some parts of the world may occur and more serious environmental havoc.

What if half of life on Earth will disappear?

Their actions Thanos not just deleted 50% of life, chosen at random, but as confirmed by Kevin Feige, President of Marvel Studios, has turned to dust exactly half of the populations of each species. Disappeared not only half the people, but half the giraffes, sunflowers, bacteria Salmonella enterica and so on. (Viruses are not entirely clear, but if they, too, would have destroyed napopolam, then we would recognize their “life” and finished with it.)

The meaning of this mass murder was to release the remaining population of intelligent life from the burden of lack of resources, which led to social collapse in the home world of Thanos. However, this is a “terrible idea on many levels,” said Ken Lacovara, a paleontologist at Rowan University, who has studied other mass extinction — a catastrophic event that occurred 66 million years ago and wiped out the dinosaurs.

At the most basic level is a bad idea, because it is not working.

People are experiencing exponential population growth throughout its history. In the 1960-ies of the human population was around three billion. Then, by 2000, there were 3 billion of us. If you destroy half of all people in 40 years we will likely return to the same number of people.

The same is true for most types, says Lacovara. Historically, companies that mined seals, whales and other animals, had a tendency to immediately annihilate half the population, moving to a new area. In most cases, he says, a 50% destruction led to the fact that the animals have reached the maximum rate of population growth — at least until they reached the number, above which the environment can no longer support.

So a massive sweep by snapping their fingers is “not a strategy that will lead to long-term effects for the population, as conceived of Thanos,” says Lacovara. However, it could lead to some strange changes among life forms, who ruled in different parts of the world.

Janet hull, a specialist in animal behavior and human evolution at the University of Keele, believes that there would be an imbalance of types associated with strategies of survival. Those species, in which many young individuals and who do not spend too much time on parental care, relying on rapid reproduction, will be able to surpass the species that have fewer offspring and give birth to him less, but invest more resources.

This means that insects, as well as fast-breeding animals, like kangaroo rats and rabbits, will feel great. Frog, says ecologist James Faulconbridge, can produce about 20,000 eggs per season, although a large number of them will become a victim of other animals, frogs easy to restore the strength for just one year. The mosquitoes are back in full force over the summer.

Other, slow-growing species such as tigers, will grow in a relatively “glacial” pace. “Halving the already small population of tigers will push them closer to the vortex of extinction which threatens them”.

Some may not be able to recover. “Species on the verge of extinction, is surely going to ruin,” says Lacovara. And cites the example of Felis margarita, sand cat, which lives in North Africa and the middle East and probably has a population in double figures. Remove the half and the cats would be too hard to find someone to breed with.

The same can be said about 50 Javan rhinos, and the about 23 Hainan Gibbons left in the wild, says Anthony looking up Caravaggio, conservation biologist from the University of South Wales. In addition to fewer opportunities for reproduction, halving will make these animals more vulnerable to inbreeding, random weather events, disease, hunting and poaching.

Hull explained that these rapidly breeding animals can slip into the empty space, liberated not only their appearance, but also other, more rare species. The end result will be a simplified global ecosystem in which rare animals become more rare and less diverse genetically.

There is also a probability that the relationship is predator-prey, such as the relationship between desert lions and giraffes, or mutualistically relationship — as in bees and flowers — will fail. But to speculate what will happen in each of these pairs difficult. In each pair can be winners and losers, and predict where will tilt the scales, it is unrealistic.

Ben Liberton, a microbiologist and science Communicator, I thought about what might happen to earth’s bacteria. People — huge vessels with trillions of microbes — will be in order, as and without that regularly take antibiotics, potentially destroying a huge part of the intestinal bacteria. However, because the composition of the microflora varies from person to person, the “split” in it can cause growth of bacteria that previously were suppressed, resulting in a delicate balance will be disturbed.

“If that happens on the planet, it is likely that some ecosystems will be fine, but some will suffer,” says Liberto. His main concern is that will hurt the microbes in the soil that control the cycles of nutrients and microbes in the ocean and soil that bind nitrogen. If half of them suddenly disappear and they will not quickly restore strength, it will be a problem for life that relies on these nutrients, primarily plants.

However, regardless of whether you are interested in macro or Microbiology, the majority of experts agree in opinion that “welcomecasino” — nonsense in comparison with what was wrong with life in the past.

Alfio Alessandro Chiarenza, doctor of science and a paleontologist at Imperial College London, says that these fossils clearly show that things like falling asteroids, long-lasting volcanic eruptions and rapid climate change, pose a real problem, next to which Thanos is not close. The great extinction — the mass extinction that took place 252 million years ago was caused by climate change due to volcanic activity destroyed up to 96% of all marine species.

“Life was almost completely destroyed,” he says. Those who survived, benefited from the generosity of the remaining resources.

And if you forget, uncontrolled pollution, the deterioration of environment and rapid climate change caused by human activity today is causing a sharp reduction of many forms of life around the world. However, to evaluate the rate of extinction of various species is not so easy. From corals to amphibians, human activities adversely affects a variety of species.

There is a possibility that sudden death could help some species to the brink of extinction. Falconbridge noted that the loss of half of the people will be the incentive for many species that are currently disappearing due to the degradation of habitats. But the plan of Thanos is unlikely to have helped the species in General, and definitely not a visionary.
