But that doesnt seem to be the scariest. The key problem is that we still dont understand the health risks associated with it, and its difficult to assess the harm of intake to humans.

Whats more, fragile babies seem to be suffering from the potential effects of plastic particles entering the body.

Previous research: one credit card a week?

In mid-2019, the University of Newcastle, Australia, commissioned by the world natural foundation, combined 52 existing research data to estimate the global per capita plastic intake, and the results warned people that the global average intake of about 2000 plastic particles per week, weighing 5 grams of plastic, is roughly the weight of a credit card.

According to the study, plastic particles, such as water, drinks, seafood and salt, are found in countless daily foods and drinks. Among them, the largest source of plastic intake should be drinking water. Ordinary people who drink bottled water or tap water every week may consume up to 1769 plastic particles.

After birth: or exposed to millions of plastic particles a day

On the 19th, a human health report published by the British journal Nature Food said that when using baby bottles containing polypropylene to make standard formula milk powder, the bottle may release plastic particles, which will directly affect the most vulnerable and early stage human infants.

The team found that plastic particles released from each bottle ranged from 1.3 million to 16.2 million. These bottles continued to release plastic particles during the 21 day test period, and the amount of plastic particles released varied with water temperature and other factors.

Using these data, the Irish team developed a potential global model of human initial exposure to plastic particles. They estimated that babies fed on polypropylene bottles were exposed to an average of 1.6 million plastic particles per day for the first 12 months of life.

Amazing data! But the impact remains unclear

The pattern of exposure varies from region to region: Africa and Asia have the lowest potential exposure, while Oceania, North America and Europe have the highest potential exposure. They concluded that infant exposure to plastic particles may be higher than previously thought, and more research is needed to understand how plastic particles are released from plastic products in contact with food during daily use.

Richard lampy, a professor at the UKs National Oceanographic centre, said it was difficult to assess the impact of intake without understanding the health risks involved. Because of the great uncertainty of plastic hazards, its potential impact needs to be further studied.

Scientists Philip schwaber wrote in an opinion paper: the new study proposed a shocking degree of exposure to plastic particles, but the actual impact on infant health needs further investigation, because for people at this stage, the impact of plastic particles and nano plastics on human health is still unclear.

New changes in the earth crisis, plastic particles appear in the human body, which is self eating? (source: ~)

Is Hawkings prediction to be verified? Scientists found residual plastic particles in human feces

The emergence of plastic products to a large extent convenient for human beings, and plastic with its own cheap, diversity, extensive use and chemical stability quickly occupied peoples daily life.

If you look around you now, I believe you can find a lot of plastic products. Almost all commodities nowadays cant do without the decoration of plastic. The food we eat and the water we drink should also be packaged with plastic. Even the clothes you wear are mixed with polyester fiber.

In fact, the components of plastics exist naturally in nature and will not have any impact on the natural ecology. However, all the plastic products we see are man-made and the quantity is very large.

If you think about how much plastic garbage you have to make every day, and how many people on earth will throw away plastic products every day. Even if you throw them into the garbage can, it is actually a kind of pollution.

Because plastic is very corrosion-resistant, it is not easy to decompose naturally. Burning it is not a way, and it will pollute the atmosphere. Therefore, plastic waste has become a headache for human beings. At present, we can only make the earth digest slowly by burying it.

The ecology of the earth is better than that of an organism, and it also has its own bearing capacity. If anything is made and used too much, it will be reversed at the extreme, and will have a lasting impact on the earth itself and our own life.

On average, nearly 8 million tons of plastic products are brought into the ocean by land currents every year, and then transported to all parts of the ocean through ocean currents, even in the deepest trenches on earth.

If we can pump out all the seawater, you will find that most of the plastic that we make now lies on the bottom of the sea. The plastic will decompose into tiny plastic particles in the ocean after being eroded by sunlight and sea water.

Animals in the ocean, from the smallest rich creature to the largest whale, will inevitably eat these plastic particles into their bodies as they eat, and then the plastic will enter the earths food circle.

Layer by layer, up to the human beings themselves. Were self feeding, so its no surprise that scientists have found plastic particles in human feces. Do you think its strange? We use plastic all day long. Its strange that they dont get into our bodies.

Its not just food. There are risks in watching the world. As mentioned above, many of our clothes are not made of pure cotton, and most of them are made of synthetic fibers (i.e. polyester), such as polyester and acrylic acid.

These things will fall off the clothes and float into the air, and then they will be inhaled into our bodies. When washing clothes, these fibers will be brought into the fresh water resources of the earth along with the waste water.

In the long run, the content of these fibers will be higher and higher, and they will continue to accumulate in the body of organisms. If you think about the high polymer molecules that nature needs millions of years to decompose, organisms cant digest these things.

Studies have shown that microplastics may cause damage to the reproductive system and liver. We have found microplastics in birds, fish and whales before, but in recent years, scientists thought that human beings must not escape the plastics attack, so they conducted research on human body.

The subjects included three men and five women, aged between 33 and 65, from seven different European countries and Japan. Participants recorded food for a week and then provided fecal samples, all containing plastic particles, for testing.

Over the course of a week, two of the eight participants chewed gum every day, six ate seafood, and they all ate food packaged in plastic, and they drank an average of 0.7 liters of PET bottled water a day.

Scientists found nine of the most common plastics in their faeces: pet and polypropylene (PP), common ingredients in plastic food packaging and synthetic clothing.

In terms of quantity, fecal samples contain an average of 20 plastic particles, ranging in size from 50 microns to 500 microns. (human hair, by contrast, is only 100 microns thick. )

It is a certain fact that every human body has been invaded by plastic particles or plastic fibers. However, scientists are not very clear about the way in which these plastics enter. It is also unknown what kind of risks will be caused to human beings in a short or even long term.

You see, the food packaging bags we usually see, including any plastic products, look good, but they will fall off and their tiny fibers will not only be inhaled, but also fall on the food. Our eyes cant find this tiny invasion.

The other is, as mentioned above, has the food itself been contaminated by plastic? The question is much more than that. Once plastic nanofibers enter the human body, will they enter the bloodstream, lymphatic system, or even the liver?

So far, all these questions have been a mystery.

This is why the use of plastic bags has been vigorously controlled in recent years. The goods made by human beings are not only polluting the nature and affecting the survival of the earths creatures, but also are eating back at human beings.

A whale shark passes by a plastic bag in the Gulf of Aden near Yemen. Despite their large size, whale sharks are still threatened by plastic ingestion.

A gardener in Queensland, Australia, decorates its home with broken glass, plastic toys and other human waste.

A sponge crab covers itself with a layer of transparent plastic. Sponge crabs usually cover their shells with sponges to avoid predators. But this kind of artificial covering cant provide enough protection.

It can be seen that the plastics made by human beings are now ubiquitous on the earth, and other organisms can only be forced to live with them. And these creatures will return the plastic to humans again.

Hawking has expressed his concern about the future of mankind on many occasions before his death. Among them, he said that the destruction of the earths environment by human beings has made the earth unbearable. However, human beings can not leave the earth, or can not find another suitable world to live in. Finally, he has to bear the bitter fruit of his own.

The pollution caused by the plastic problem is only a microcosm of our human pollution environment. With the air pollution, water resources pollution and the excessive development of resources, human beings are gradually destroying their only home. Hawkings concern must be right that one day the earth will no longer be suitable for survival.
