다행성 종족이 된 인간은 끝내 모든 행성을 오염시킬 거라고?

In the movie Space War, aliens invade the earth. The human army becomes powerless in front of the aliens' technology, and humans are caught by aliens and die. But in the second half of the movie, the situation suddenly changes. Aliens are now infected with microorganisms living on Earth, so they are completely powerless. So, thanks to the microorganisms on Earth, we were able to defeat the aliens. The ending of the movie is a bit empty, so I'll give it 5 out of 10. To continue the movie review, this movie tells a scientific story. Someday, aliens will come to our earth, and they may get sick. A huge meteorite with organic substances may fall on the earth and be contaminated by unknown microorganisms. On the other hand, our humanity may contaminate alien planets with microorganisms. Humanity in the real world now has the technology to go to other planets like the moon or Mars. Also, after a very long time, if the earth's rocket technology develops much more, it may reach a planet hundreds of light years away where life exists someday. For example, a place like Pandora. At this time, if microorganisms on Earth contaminate an alien planet, we don't know what will happen. In the worst case, all the living things on the planet may die. Hey, you're talking too much like a fantasy. Is that so? In fact, something similar has happened in the history of our humanity. After Columbus discovered the Americas in 1492, many Europeans boarded a ship and crossed the Atlantic Ocean to the Americas. At this time, not only people died. There were many insects, grass, viruses, parasites, and bacteria that came from the Eurasian continent. There were also animals. In the end, many of the native people died of diseases. The ecosystem of the Americas was ruined. One of the reasons why so many native people died was natural gas. The natural gas virus began to spread when humans raised cows. At that time, the native people of the Americas had never bred large animals like cows, so there was no natural gas. In addition, infectious diseases such as Janctivus, Diphtheria, Rheumatoid Arthritis, and Influenza spread together. The disease was so severe that the Indians died just by looking at the Spanish soldiers. The population of the Peruvian Inca Empire was reduced by more than 90%. It was a really scary biochemical attack. The history of environmental pollution is countless. Two British rats landed on an island, and all the species that lived on the island died and became the heaven of rats. The story that the bats and bullfrogs that landed in Korea ate all the native animals in Korea and devoured the habitat. The story of the rabbit army that spread all over Australia. Looking back on the history of mankind, there are so many cases of humans going somewhere new to pollute, destroy the ecosystem, and turn over the toilet. I can't guarantee that this won't happen even if we go to another planet other than Earth. So when humans go to a solar planet or an alien planet , we have to make a kind of rule that humans should not pollute the environment there. This is called a protection of the planet. No, do you have to do this in space? Yes, it's really cumbersome, but you have to do this. Because the survival ability of microorganisms on Earth is beyond imagination. There are reports that bacteria survived in radioactive areas. There are cases of microorganisms and bacteria surviving in the solar radiation, solar radiation, and vacuum space close to absolute zero. Microorganisms surrounded by rock or clay have a much higher survival rate. Microorganisms like bats are very persistent that can survive in extreme environments. We humans still don't fully understand the limits of these guys. If we humans explore an alien planet, let's say that a planet is just a mess because of the microorganisms that aliens have. This is a big deal. So, according to the protection of the planet, cargo, aliens, and garbage must be kept clean. So that no material on Earth pollutes other planets. When you hear about the protection of this planet, it's similar to the quarantine procedure. We've been washing our hands often and wearing masks for years because of the disease. There's an infirmary in the hospital, there's a protective suit, and there's a quarantine car. It's right to pass the disease you have on to other people, and it's right to prevent other people from passing the disease on to you. Now, let's take a closer look at the protection of the planet. The concept of protection of the planet was in the 7th Congress of the International Space Federation. Then, the issue of protection of the planet was discussed by the Space Research Committee in 1959, and a resolution was announced in 1964. To summarize the contents of this resolution, It's important to find alien life. But in the near future, I think only in Mars in the solar system can our humanity find life. Well, the search for life is all good. Let's not pollute Mars. Let's do everything we can, including sterilization of spaceships, and explore it as cleanly as possible. In 1967, the United States, the Soviet Union, and the United Kingdom gathered to ratify the UN Space Treaty. If you look at the structure of this treaty, there is a similar legal basis. The parties of this treaty cooperate with each other when exploring the solar system, including the Moon, and follow the principles. At this time, if you think you're going to lose or lose interest in another country, you can go through an international agreement, and even if you don't, the party can request an agreement first. The UN Space Treaty is slightly more forcibly than the Space Research Committee. 104 countries, including Korea, have signed this treaty. In addition, 24 countries have signed it. Oh, but is it okay for countries that have not signed this treaty not to follow this treaty? In the United States, this treaty was adopted unanimously. So now, even if you have international jurisdiction, even if you don't sign it or don't follow it, all countries around the world will be subject to this treaty. There are several provisions for the protection of this planet. First, it is a provision for the sample return mission. For example, if SpaceX goes to Mars and collects the soil, air, ice particles, etc. and brings them to Earth. But you don't know what's in the material of Mars. There may be some organic matter. If there was a fatal organic matter in Mars soil, if you bring it to Earth as it is, germs of the Earth may spread. To prevent this from happening, it is a protection of the planet for the sample return mission. There is also pollution between planets. If the material of the Earth pollutes Mars, it is called pure pollution. If the material of Mars or the guys stuck on the meteorite pollutes the Earth, it is called reverse pollution. No, but honestly, no one is inspecting the creature stuck on the rocket, and no one is watching while exploring the planet. It's just a word, but it seems to be quite well maintained. At that time, the United States, which was planning Apollo, called all experts in various fields, including the National Reservation, the Agriculture Department, the Wildlife Protection Agency, NASA, etc., to discuss Earth pollution that may be there. It may be dangerous even if this exploration succeeds. So, through the Apollo project, when you bring a material like a stone from the moon, you have to put it in a completely sealed box. Astronauts who came back after the exploration should be quarantined for at least 3 weeks. According to this decision, Neil Armstrong, Buzz Aldrin, and Michael Collins, who came back from the Apollo 11 mission and collected the lunar soil, and the lunar soil as well. It was examined in detail in a glass box. In addition, the probe lines that are fired to explore the alien planet must have been fired after sterilization. And there's a nuclear battery in the Cassini ions, which were the Galileo and Saturn probe lines, which were the Jupiter probe lines. The material is plutonium. If the probe lines end their lives on a planet with land, they can emit very deadly radiation for a long time. So, in the case of a probe with a nuclear battery, it collides with a gas planet and destroys it. Efforts to protect the planet are still underway. In the case of the European Union, we have built a new clean room to clean up the microorganisms on the planet. At the European space base and launch site, we built a new microbial laboratory. In the case of NASA, we established a planet protection agency. A few years ago, NASA announced its recruitment to Twitter as a planet protector. The job of the planet protection agency is to protect the hygiene of the solar system cleanly. Depending on the possibility of pollution and the mission of a planet that seems to have a creature and a creature that seems to have a creature, it is strictly applied. What about today's planet protection? NASA is planning to land on the moon again by 2024. Private companies such as SpaceX are said to go to Mars. Because of this, there may be more pollution on other planets in the near future. So we need to discuss planet protection more. Fortunately, Mars exploration has been unmanned so far. Thanks to this, Mars can be free from Earth's microorganisms and viruses. But if humans start exploring Mars within a few years or decades, it will be difficult for Mars to avoid pollution. So scientists have to seriously discuss these issues. We have to strengthen the standard of pollution, or we have to raise the standard of living organisms that seem to have lived or are still living. The place where scientists are most concerned is a special area such as Hellas, where there are traces of life. If the measure is not taken quickly, Mars may be polluted during human exploration, so we may lose the opportunity to study the Mars ecosystem forever. We found some life on Mars, but it turned out to be from Earth. Or there was a life on Mars, but all of them were polluted by earthmen. This shouldn't happen.
