With the development of human beings, science and technology have been popularized in many areas, and because of this, people feel the convenience that science and technology bring to us, but at the same time, the convenience of science and technology also brings many problems. Many scientists and environmentalists are troubled by the plastic bags of white polluted garbage, which are harmful to the entire marine environment or animal ecology. And scientists have also found a lot of garbage in various aspects, which has the following significance.
First, human pollution of the environment is becoming more and more serious. First of all, the first point is that although human beings now feel that the natural environment is taking place, some slow changes, such as the current global warming effect and global warming, which is the slow result of human beings transforming nature. But it is precisely because of this that scientists have found plastic pockets in many areas and inside the bodies of animals, which should be reflected on why the amount of human garbage can harm the inside of one of the bodies of these animals.
But it is precisely because of this that one of the natural activities of human beings has seriously endangered the entire natural environment. <>
Second, a polluted plastic bag of human beings has penetrated into many environments. Another point is human pollution, plastic bags have penetrated into many industries, such as in nature and tourism, people can see a lot of floating white garbage on the ocean. Because of this, the world is now stepping up efforts to control such pollution, but such a prevention and control measure is still very small.
As far as white pollution is concerned, people feel that such a prevention and control behavior is not thorough enough. <>
3. Many plants and animals are being affected. The last point is that plastic bags have been found on many animals and plants, some plastic bags will seriously affect the growth and reproduction of animals, and the most terrifying point is that these plastic bags will directly destroy the extinction of a group.

Scientists have found plastic waste in all aspects, which means that the phenomenon of human littering is serious and the disposal of plastic waste is not reasonable. At the same time, it also means that plastic waste is very difficult to degrade in nature.
-
This means that the environment may be seriously threatened and damaged, our environmental awareness is still very low, and the natural environment is very miserable, so we must pay attention to it.
-
It means that plastic is really difficult to degrade garbage, and it is difficult to deal with, if it is not stopped in time, the earth will soon be flooded with plastic waste, and there is no way to use it.

In the 20th century, scientists created something special, and it was plastic. This substance is extremely inexpensive to make and highly malleable. With these two points, it has become the main material of human society.
It's a pity that plastic has a fatal shortcoming, and it is very troublesome to degrade. Now, scientists have found plastic particles in human feces, what is going on?
In 1906, the scientist Beckland had the whimsical idea to synthesize plastic by adding some chemicals to a certain resin. In the scientific community, people are very excited about its appearance. Because it is relatively heat-resistant and stable, after some treatment, this material can be processed into many things, such as laminates, coatings, etc.
Outside of Chinese New Year's Eve, it became polyethylene with its malleability and appeared on the stage of history.
2. In daily life, there are not a few plastics that humans are directly exposed to. For example, express boxes, mineral water bottles, plastic bags, etc. Many years ago, plastic bags were arguably highly prized.
It truly does its job and is used in all walks of life. Even in aerospace, construction, mechanical and other engineering, it is also used as the first material. Coupled with its own inexpensiveness, it can also be used as a raw material.
So why is such a perfect existence forbidden after so many years?
3 In the beginning, there was only one way for humans to solve plastic waste, and that was incineration. However, this treatment method will emit a large amount of greenhouse gases and toxic gases into the atmosphere. Those highly stable materials cannot be processed by burning alone, and they can only be left to damage the environment.
At this point, scientists really paid attention, but unfortunately it was a little too late. After the combustion of plastic products, the gases produced not only pollute the environment, but also produce acid rain. As for those that are landfilled, they cause damage to the underwater ecosystem.
4 In fact, Stephen Hawking has long said that we do have the technology to destroy the Earth, but we do not have the ability to escape its control, and humanity will eventually suffer the consequences. According to preliminary statistics, human beings discharge at least 8 million tons of garbage into the ocean every year, and such a huge "garbage team" has dealt a fatal blow to the underwater ecosystem. Some marine creatures have lost their lives, while others have been salvaged by humans, and plastic particles from their bodies have entered the human body.
5 At the same time, plastic molecules have been detected in oysters, fish, shellfish and other foods. In the human test, scientists asked eight experimenters who ate food packaged in plastic every day, and after a while, when they tested human feces, they found plastic particles in it. At that time, a total of nine plastic components were detected.
It can be seen that Hawking's prophecy is really going to come true, and we are really being eaten by technology. How much time do you think we have for the current state of humanity?

Although plastic particles will cause harm to people, this society needs to use these plastics, so there is no way to stop the production of plastics, which leads to the amount of plastics, and then it will endanger the health of our human body, which seems to be unavoidable.
There will be a large number of plastic particles in the food we usually eat or the water we drink, and there is no way for this pollutant to enter our body through various channels. It has seriously endangered our health, and now the pollution of plastic particles is very serious, which should have harmed nature, but now it has taken revenge on human beings, but we have no way to deal with them.
Now the pollution of plastic particles is no longer under human control, 50% of human beings have this substance, and there are as many as nine types of plastic particles, and the density of these particles is also very strong. On average, there are 20 plastic particles in every 10 grams of feces.
Most of these plastic particles are found in tap water, and even every country is not immune, even in the mineral water we drink. According to our current filtration system, it is impossible to filter such particles, so these plastic particles have always existed in our lives. Not only the water we drink, but also the salt will have this kind of plastic particles, which is very harmful to our human beings, and if we can't think of a way to solve it, then the consequences are unimaginable.
So what class are you, are there a lot? Actually, a lot of the time.
Got echolocation on bats, radar was invented.
This is very likely to happen, there are a large number of pulsars in the universe, but due to their weak signals, they are easily overwhelmed by artificial electromagnetic interference, and only a small number of them have been observed so far, they are natural data stations that transmit signalsBut the signal is mottled and noisy, and it doesn't help if humans don't receive the instrument very accurately. >>>More
Don't talk about science with scientists, just like don't talk about learning with college entrance examination students.
I think it's mainly because the environment is getting worse and worse, so there will be plastic in the snow.
