The emergence of plastic products has greatly facilitated humans and plastics have quickly occupied people’s daily lives with their own cheapness, diversity, wide application and chemical stability.
If you look around you now, I believe you can find a lot of plastic products. Almost all of the products are inseparable from plastic. The food we eat and the water we drink must also be packed with plastic, even if you wear it. My clothes are mixed with polyester fiber.
The composition of plastic actually exists naturally in nature, and it will not have any impact on the natural ecology. However, all the plastic products we have seen so far are artificial, and the number is very large.
You think about how much plastic waste you make every day, and think about how many people on the earth throw plastic products away every day. Even if you throw it in the trash, it is actually a kind of pollution.
Because plastic is very resistant to corrosion, it is not easy to decompose naturally, burning is not a way, and it will pollute the atmosphere, so plastic waste has become a headache for humans. At present, we can only slowly digest the earth by burying it.
The ecology of the earth is like a living thing. It also has its own ability to bear. Anything that is made and used too much will be absolutely counterproductive, and will have a lasting impact on the earth itself and our own lives.
On average, nearly 8 million tons of plastic products are brought into the ocean by land currents and then brought to various parts of the ocean through the ocean currents. Even the deepest trenches on the planet we have found plastics in.
If we can drain all the seawater, you will find that most of the plastics currently manufactured by humans are lying on the bottom of the sea. The plastics in the ocean will be broken down into tiny plastic particles by the erosion of sunlight and seawater.
Animals in the ocean range from the smallest rich creatures to the largest whales. They will inevitably eat these plastic particles into the body during the eating process, and then these plastics will enter the earth’s food circle.
Pass up layer by layer until the human beings themselves. This is a bitter fruit for us, so it is not surprising that scientists found plastic particles in human feces. Do you find it strange? We use plastics all day, and it’s strange that they don’t enter our bodies.
Not only food, but there are risks in watching the world. As mentioned above, many of our clothes are not made of pure cotton. Most of them are clothing made of synthetic fibers (that is, polyester), such as polyester and acrylic acid.
These things will fall off the clothes and float into the air, and then we are inhaled into the body. When washing clothes, these fibers will be brought into the earth’s freshwater resources along with the waste water.
Over time, the content of these fibers will become higher and higher, and will continue to accumulate in the body of the organism. Think about it, nature needs high polymer molecules that can be broken down for millions of years. There is no way for organisms to convert these things “Digest” away.
Studies have shown that microplastics may cause damage to the reproductive system and liver. We have previously found microplastics in birds, fish and whales, but in recent years scientists have thought that humans will certainly not be able to escape the counterattack of plastics, so it will harm the human body Do a research survey.
The research subjects included 3 males and 5 females, aged between 33 and 65, from 7 different European countries and Japan. Participants recorded food for a week and then provided stool samples for testing. All stool samples contained plastic particles.
Over the course of a week, two of the eight participants chewed gum every day, six of them ate seafood, and they all ate foods wrapped in plastic, and they drank an average of 0.7 liters of PET (polyphenylene terephthalate) per day. Bottled water made of formic acid, glycol esters).
Scientists found nine of the most common plastic components, PET and polypropylene (PP), in their feces, which are common ingredients in plastic food packaging and synthetic clothing.
In terms of quantity, the stool sample contains an average of 20 plastic particles, ranging in size from 50 microns to 500 microns. (In comparison, human hair is only 100 microns thick.)
It has been a certainty that every human body has been invaded by plastic particles or plastic fibers, but the way in which these plastics mainly enter is not very clear to scientists, and what kind of risks will be caused to people in a short time or even a long time. unknown.
You see, the food packaging bags we usually see, including any plastic products, look good, but they will fall off and their tiny fibers, they will not only be inhaled, but also fall on the food, this tiny Our invasion is completely undetectable by our eyes.
The other is mentioned above. Are the foods we eat already contaminated with plastic? The problem is much more than that. Once plastic nanofibers enter the body, will they enter the bloodstream, lymphatic system, or even the liver?
So far, all these problems have been a mystery.
This is why the use of plastic bags has been vigorously controlled in recent years. The goods manufactured by humans are now not only polluting nature, affecting the survival of the earth’s living beings, but now also antagonizing humans.
In the Gulf of Aden near Yemen, a whale shark passed by a plastic bag. Although the whale sharks are huge, they are still threatened by eating plastic.
A gardener bird in Queensland, Australia, decorates his home with broken glass, plastic toys and other human waste.
A sponge crab covered itself with a layer of transparent plastic. Sponge crabs usually cover sponges on their shells to avoid predators. However, this artificial covering cannot provide sufficient protection.
A group of hyenas forage in the rubbish dump in Merkel, Ethiopia. Plastic fragments are scattered in leftover food debris and bones discarded by humans.
It can be seen that the plastics made by humans are now ubiquitous on earth, and other living things can only be forced to live with these plastics. And these creatures will return these plastics to humans again.
Hawking had expressed his own concerns about the future of mankind on many occasions during his lifetime. Among them, he said that the destruction of the earth’s environment by humans caused the earth to be overwhelmed, and humans could not leave the earth, or they could not find another suitable for survival. In the end, the world can only eat bitter fruits.
The pollution brought about by the plastic problem is only a microcosm of our human pollution environment. Atmospheric pollution, water resource pollution, and the transitional development of resources, human beings are destroying their only homes little by little. Hawking’s worry is definitely right, one day the earth will no longer be suitable for survival.
The earth will still be there, but we humans have disappeared. We can’t solve the plastic problem, we can only work hard from the roots, and advocate the use of fully degradable plastic products.
