Present of dangerous earth than Tanos

Infiniti War, the previous work of the recently released movie Avengers & Games, destroys half of life in the universe. It collects all the infinite stones and then taps the fingers to blow up half of the whole universe life. What would happen if, in fact, the earth’s life was halved?

Such indiscriminate extermination can be thought to be a disaster for the ecosystem. Of course, if you are in a dangerous state, you may be pushed into extinction and a significant ecosystem confusion may arise.

What we have erased from the movie includes not only half of all human beings, but also animals, plants, and bacteria. The original purpose of this massacre is to reduce the life of the universe in half, so that the remaining population will have enough resources. The idea is set in the background that Tanos’ homeland has collapsed due to crises such as overpopulation and food shortages in Titan.

This reminds me of dinosaur extinction 66 million years ago, another form of genocide. Experts say that Tanos’s plan is a terrible idea in many ways. Humanity is experiencing a dramatic population growth, as can be seen in history. In the 1960s, the population was 3 billion, but in 2000, 40 years later, 3 billion increased again. Even if we eliminate half of the population, it will be back in place 40 years later.

This principle applies to most animals. Historically, mankind, which began to capture other animals such as seals and whales, hunted half of the population as soon as it entered the new era. If most of the population is halved, the growth rate of the animal will be at its maximum until at least the environment can not be maintained.

Another opinion is that species imbalance can occur according to survival strategies. An animal with a high fertility and a high number of offspring and not much time in childcare can be able to eliminate the opposite animal. In other words, creatures that breed fast, like kangaroo rats and rabbits as well as insects, can do well. The frog lays about 20,000 eggs at a time. The population can be recovered in about one year. The mosquito will also return to my number in midsummer.

On the other hand, animals that take time to grow, such as tigers, increase their population at a relatively slow rate. In this respect, if the number of tigers that have already been killed is halved, it will be close to extinction, which was a problem from the past.

Some creatures can not survive at all. It is an endangered species. If half of the sand cat inhabits North Africa and the Middle East, it will be harder to find a breeder. Those who are left in the wilderness and the rhinoceros or Hinan gibbons will walk in a similar way. Not only are there fewer breeding opportunities, but they are even more vulnerable to inbreeding, weather deterioration, hunting and poaching as they are halved. This means that rare species become more rare and genetic diversity can be reduced and become a simplified global ecosystem.

Also, symbiotic relationships such as lions and giraffes, predators, bees and flowers, can become unusual. Such complex interrelationships result from the cycles of both species. It is difficult to predict the ecosystem balance.

Even microorganisms can change their composition and prevent the growth of bacteria, which is inhibited by other bacteria, and the delicate intestinal bacterial balance can be confused. And if half of the soil microorganisms that circulate nutrients and the microorganisms that fix the nitrogen in the soil or everywhere suddenly disappear and can not be restored, there could be problems with the life of plants and other nutrients.

Of course, the big impacts of the past, the volcanic eruptions over a long period of time, and the rapid climate change can be fatal to the real earth. Climate change induced by volcanic activity has caused mass extinctions in the past 252 million years and 96% of all marine life has been killed. The creature was almost safely extinct. The world is experiencing a rapid decline in biological populations due to unprecedented environmental pollution and deterioration, and rapid and artificial climate change. Many creatures, from coral to amphibians, are getting worse. The catastrophe that Tanos has caused may also be said to be less severe than that which mankind is now producing on its own. The current biodiversity crisis points out that most of the animal population is on the verge of extinction due to human activity.
