 Does the global average eat one credit card a week? Plastic particles have reached the baby

In mid-2019, the University of Newcastle, Australia, was commissioned by the World Wide Fund for nature (WWF) to estimate the global per capita plastic intake after synthesizing the existing 52 research data. The results warn people that the global average intake of plastic particles per week is about 2000 particles, weighing 5 grams of plastic, which 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

Among the non fiber plastics, the annual output of polypropylene accounts for 20% of the total output, which is the most widely used plastics in food preparation. However, little is known about the release of plastic particles from such containers.

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.

Under the disinfection and formula brewing conditions recommended by the World Health Organization, the Trinity College Team in Ireland tested the release of plastic particles from 10 baby bottles, which represent most of the bottles in the global online market. They are either made of polypropylene or contain polypropylene based accessories.

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

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: ~)

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.

Think about how much plastic waste you make every day, and how many people on earth throw plastic products at hand every day. Even if you throw it into a trash can, it is actually a kind of pollution.

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.

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.

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.

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.

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.

A group of hyenas forage in a garbage dump in Meckel, Ethiopia. Plastic debris is scattered in food scraps and human discarded bones.

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.

The earth will still be there, but we humans will have disappeared. We cant solve the problem of plastics. We can only work on the root causes. We can only encourage everyone to reduce the use of plastics every day. After all, the earths ability to digest plastic is far from keeping pace with human production.
