It should be some bacteria and viruses and the like, these creatures have a particularly strong ability to survive and reproduce.
-
It will be the type that wants to conquer humans, and alien creatures will only invade and occupy our resources, and will not want to be friendly with us.
-
I hope that it is an alien with a high appearance, and it must conform to our aesthetics, so that even if it is the end of life, there will be no regrets, after all, it will not be more frightened by the strange appearance of the alien.
-
I think it's going to be an alien organism that is higher than human intelligence.
-
The creatures that cannot be resisted by the current means of the earthlings can only be creatures with infectious viruses, and only in this way is the invasion in my sense.
-
This alien creature can kill a cow in the air, and as a human being is even more vulnerable to it, only then can I fear its existence.
-
Most likely, it is the kind of highly intelligent creatures, I think humans are brave enough, if they can still invade the earth, they must be highly intelligent creatures.
-
5.Now that the detection equipment on the earth is very advanced, I think it should be the kind of small, dense horror creatures, and it is not visible to the detection equipment.
-
Gravity doesn't do anything to them at all, and the fact that this creature can step up to ten meters in one step is the scariest thing I think.
-
They are alien creatures who can master time and space, and I am just a small thing in his hands, and I feel like an ant when I see this creature.
-
The greatest tragedy of human beings is that they are self-centered, and this kind of creature is centered on the whole universe, and I think human beings are only a part of what he wants to conquer.

The reason why invasive alien species are harmful is that they reproduce rapidly, their numbers increase geometrically, and due to the lack of natural enemies, they often grow into new dominant species in the local area, seriously damage local biodiversity and ecological security, and also cause serious biological pollution and irreversible damage to the ecosystem. For example, the following invasive alien organisms: water hyacinth is native to South America, introduced into China as an ornamental plant in the early 20th century, and later promoted and planted as pig feed.
Goldenrod canadensis is an ornamental plant introduced from North America in Shanghai and other places in China in the 30s of the 20th century, and later escaped into the wild, with a strong ability to reproduce and quickly occupy space, suppress the growth of native plants, and destroy the ecological balance of vegetation in the invasion area. The Brazilian tortoise, also known as the red-eared tortoise, is mostly found in Brazil, with a few species found in the United States. The Brazilian tortoise is recognized as an ecological killer in the world, and many countries such as China have listed it as a dangerous invasive alien species.

Biologically, an alien species is a species, subspecies or lower taxa that occurs outside its range and location from the silactic squire, including any part, gamete or propagulum of these species that can survive and reproduce.
Alien species invasion refers to the process of biological species migrating from the place of origin to the new ecological environment through natural or man-made means, which has two meanings: first, the species must be alien and non-native to the territory; Second, the alien species can settle, reproduce and spread in local natural or artificial ecosystems, and eventually significantly affect the local ecological environment and damage local biodiversity. Invasive alien species can disrupt the naturalness and integrity of landscapes, destroy ecosystems, endanger animal and plant diversity, and affect genetic diversity. As of 2013, 544 species of alien pests have been identified as invading China, of which more than 100 are serious.
Among the 100 most threatened invasive alien species in the world announced by the International Union for Conservation of Nature, more than 50 species have invaded China. China's economic losses caused by this exceed 200 billion yuan every year.

As the name suggests, the invasion of alien species is the invasion of animals and plants from other places to the local area, there are no natural enemies, they multiply in large numbers, affecting the survival of local native animals and plants.

Analysis: "Biological invasion" refers to the phenomenon that a certain organism is naturally introduced from other places or artificially introduced into the wild state and causes certain harm to the local ecosystem. Alien organisms have a number of limiting factors in their places of origin that prevent the vicious expansion of their populations, among which predators and parasitic predators play a key role in keeping their population densities below a certain number.
As a result, those alien species usually do not pose a significant hazard in their place of origin. However, once they invade new areas and lose the control of their predators, their population densities can grow rapidly and spread rapidly. In nature, there is a food chain in the ecological environment, and natural enemies restrain each other, and once a certain organism is artificially extinct and artificially introduced, it will produce a series of unimaginable consequences.
Therefore, some foreign scholars regard blind introduction, habitat shrinkage and fragmentation, overkilling, and the secondary effect of species extinction as the four major causes of species extinction, and visually call it the "devil's quartet".
There are two types of biological invasions: intentional and unintentional. With the introduction of species, these immigrants may benefit human beings on the one hand, and on the other hand, they may also have a certain impact on the local ecological environment and even economic development.
How to solve the problem of "biological invasion", the "illegal immigration" of the biological world, so that they do not pose a danger in a foreign land? The experts are: first, we should introduce species cautiously and strengthen the management of the introduced species; Second, it is necessary to find out the types and harmful status of existing alien harmful species in China; Third, it is necessary to strengthen the prevention and control of major alien harmful species and the comprehensive management of them.
The International Union for Conservation of Nature (IUCN), adopted in Switzerland in February 2000, states that "for thousands of years, oceans, mountains, rivers and deserts have provided isolated natural barriers to the evolution of rare species and ecosystems. In recent centuries, these barriers have become ineffective due to global change, and invasive alien species have traveled across oceans to reach new habitats and habitats, and have become invasive alien species. ”

With the convenience of human transportation, more and more foreign animals have entered our country. If we don't pay attention to it, it will affect our ecological environment and cause widespread concern. Jinling Customs, which is part of Nanjing Customs, inspected the letter and found six plastic bottles in one mail, containing live beetles, wet wood chips and nutrients.
Six Japanese beetles were identified, four female and two male. There are plastic bottles with wet wood chips and nutrients. Each bottle contained a live beetle.
This swarm of Japanese giant spade beetles is slightly larger than the regular beetle. They are very strong and about 8 cm long. They may have been carefully selected before being mailed.
If the Japanese spade beetle enters the wild of our country and becomes an invasion target, it will bring damage to the local ecological environment and disrupt the food chain. Beetles are mainly found in Japan. It's big and aggressive.
Customs warns that as an alien species, live insects may cause biological invasions. It is forbidden to bring or mail into the country. It is a nocturnal insect that inhabits succulent trees in broadleaf forests.
Species invasion, also known as biological invasion, refers to the invasion of organisms from their original habitat into another new environment, either naturally or artificially through chain pins. Processes that cause damage to biodiversity, agriculture, forestry, animal husbandry and fisheries, production and human health. The invasion of alien species has a certain impact on regional economic development, ecological environment, and even human health and social activities.
Beetles eat the juice of adults, honey, rotting food of larvae, leaves and sap of plants, and love sweets.
Try to feed some foods high in sugar, which is very aggressive. Most adults are nocturnal and phototaxis, but there are also daytime species. The invasion of alien species has a certain impact on regional economic development, ecological environment, and even human health and social activities.
Some alien species have invaded farmland and pastures, causing reduced yields and economic losses to crops, forests and pastures. Potato beetles can cause a 30-60% reduction in potato yields, or even no harvest. In addition, quarantine, prevention and ** will also come at a huge cost.

If extraterrestrial civilizations invade Earth, why did they invade Earth? How is humanity going to deal with them?
-
Yes, every animal on the planet has natural predators where it lives, and the introduction of foreign species to the local area will be flooded due to the lack of natural predators, is it very similar to humans.
-
Humans are constantly multiplying and evolving on Earth, not invading.
-
Biological invasion refers to the phenomenon that a certain organism is naturally introduced from other places or artificially introduced into the wild state and causes certain harm to the local ecosystem. These organisms are called alien species.

No, the landlord is too yy, and human beings are conceived by the earth.
-
Humans evolved on Earth. It is considered a species of the earth.
-
No, because humans have not been extinct since ancient times.
-
Humans should not be alien invasions, we have a verifiable history.
-
Humans are not invasive alien species, we ourselves are created on Earth.
-
No, humans are the inhabitants of the earth, and there is a history of human evolution here.
-
No, human beings evolved from Earth creatures.
-
Humans are not invasive alien species, we are creatures that evolved from the earth.
-
Probably not, man evolved from apes.
The ocean covers 71 of the Earth's surface, and if all the water in the ocean were evenly spread on the Earth's surface, a 2,700-meter-thick hydrosphere would form on the Earth's surface. So some people say that the name of the earth is wrong, and it should be called "water ball". From the origin of life on earth to the formation of human society, from a primitive society with low productivity to a modern society with advanced science and technology, man and water have formed an indissoluble bond. >>>More
The universe is so big, the existence of life should be very common, but it doesn't have to be like earthlings. For example, the body may not be carbon, not necessarily a physical entity, or even a three-dimensional form. The human imagination is too limited.
