When the gods granted midas one wish, he wished that everything he touch would turn to gold. Midas was delighted, trees, rocks, all gold. But soon he found in horror when his food turned into gold as well. When he hug is daughter to saute his pain, he realized his mistake too late. The richest man in the world, was starving, heartbroken, and alone. Humanity got a similiar wish granted when we learned how to turn brown stinky goo into magic - plastic. Cheap, sterile, and covenient, it changes our lives. But this wonder of technology got a little out of hand. Plastic has saturated our environment, it has invaded animals we eat. And now its finding its way into our bodies. What is plastic? For most of our history humans, we used stuff we found in nature to build the things we needed. But te invention of plastic roughly 100 years ago completely changed our world. Plastic is made from polymers, long repeating chain of molecule groups. In nature polymers exist everywhere : cells wall, silk, hair, insect carapaces, and DNA. But it also possible to create them. By breaking down crude oil into its components and rearranging them, we can form new synthetic polymers. Synthetic polymers have extraordinary traits. They are lightweight, durable, and can be modeled into any shape. Not requiring time-consuming manual work, plastic can be easily mass-produced and its raw materials are availabile in vast amount, and increadibly cheaply. And so, the golden era of plastic began. Bakelite was used for mechanical parts, PVS for plumbing, electrical equipments, and cases, Acrylic is a shatter resistant alternative to glass, and nylon for stockings and war equipments. Today is almost everything at least partly made from plastic. Our phones, clothes, computers, furniture, appliances, houses, and cars. Plastic has long ceased to be a revolutionary materials instead it became trash. Coffee cups, plastic bags, and stuff wrapped a banana. We dont think about this fact a lot. Plastic just appears and goes away, unfortunately it doesnt. Since plastic is so durable, it takes 500 to 1000 years to break down. But somehow we collectively decided to use this super tough material for things meant to be thrown away. 40% of plastic are used for packaging. In the US itself, packaging mades up 1/3 of all wate that its generated annually. Since its invention, we have produced 8.3 billion metric tons of plastic. 335 million tons in 2016 alone. More than 6.3 billion metric tons of plastic have become trash since 1907. Piled up in one place, that makes a cube with a side length of 1.9 kilometers. So, what did we do to all this waste? 9% was recycled, 12% burnt. But the other 79% of it is sticking arround still. A lot ends up in the oceans, about 8 million tons a year. That so much plastic that it will outweigh all of the fish in the ocean in 2050. Becuse its everywhere, marin animals keep getting trapped in plastic and swallowing it. In 2015 already 90%of seabirds had eaten plastic. Many animals starve with stomach full of indigestable trash. In 2018, a dead sperm whale washed up in spain. It had eaten 32 kg of plastics bags, nets, and a drum. While this is tragic and makes for great magazine covers, there's an even more widespread, invisible form of plastic - microplastics.
Microplastics are pieces smaller than 5 milimeter. Some of them are used in toothpaste or cosmetics, but most result from floating waste that its constantly exposed to UV radiation. And crumbles into smaller and smaller pieces. 51 such particles float in the ocean where they are more easily swallowed by all kinds of marine life. This has raised concern among scientists, especially health risk from chemicals that are added to plastic. BPA for example makes plastic more transparent, but there's also evidence that it iterferes with our hormonal system. DEHP makes plastic more flexible, but may cause cancer. It would be pretty bad if microplastics are toxic, because they travel up the food chain. Zooplankton eat microplastics, small fish eat zooplankton, so do oysters, crabs, and predatory Fish, and they all land in our plate. Microplasrics has been found in sea salt, honey, tap water, and household dust arround us. 8 out of 10 babies and nearly all adults have measurable amount of phthaletes, a common plastic additive in their bodies. And 93% of people have BPA in their urine. There is little science about this so far, and now its still inconclusive. We need more research before panic is justified. But it is safe to say that a lot of stuff happened that we didn't planned for. And we have lost control over plastic to a certain extent which id kind of scary. But just to make sure, we should simply ban plastic, right? Unfortunately, its a bit complicated than that. Plastic pollution is not the only environmental challenge we face. Some of the subtitute we'd use for plastic, have a higher environmental impact in other way. For example, according to the research from the danish goverment, making a single-use plastic bag, requires so little energy and produces far lower carbon dioxide emissions compare to a reusable cotton bag, that you need to use your cotton bag 7100 times before it would have a lower impact on the environment than the plastic bag. Plastic also helps problem that we don't have a pretty good answer for at the moment. Globally one-third of all food produced is never eaten and ends up rotting away on landfills where it produces methane. And the best solution for preventing food from spoiling and avoiding unnecessary waste is still plastic packaging. It also important to note where the vast majority of the world plastic pollution coming from right now. 90% of all plastix waste entering ocean from rivers comes from just ten rivers in Asia and Africa. The Yangtze in China alone flushes 1.5 million tons of plastic into the ocean each year. Countries like China, India, Algeria, or indonesia industrialized at an impressive pace in the last few decades. Transforming the lives of billion people. This production was so fast that the garbage disposal infrastructure couldn't keep up with collecting and recycling all the new waste this brought. The bottom line is, as long as we don't adress plastic pollution from a global perspective, we will not solve it. Plastic pollution is a complicated problem. We found a magic material, and we had a really good time with it, but we nees to be careful. Or just like midas, we'll end up in the world we didn't wish for.
