The downside to the composition of plastic, and the chemical bonds which make it so strong, is that the same bonds make it resistant to the natural process of degradation. Bags that end up in landfill are predicted to take up to 1,000 years to decompose, and even then plastic molecules never disappear completely.

There was just one problem: Plastic doesn’t really compost the way a leaf might. Because its molecular chains are linked tightly together through an industrial process, those polymer chains won’t break down to become part of the soil like leaves and twigs, grass and food waste do.

Overall, plastics are lighter and more efficient than many alternatives. Their lighter weight reduces their environmental footprint by decreasing waste, energy use and carbon emissions. In multiple packaging categories, plastic is a better choice than glass.

How does plastic harm the environment? Plastic sticks around in the environment for ages, threatening wildlife and spreading toxins. Plastic also contributes to global warming. Burning plastics in incinerators also releases climate-wrecking gases and toxic air pollution.

100 million marine animals die each year from plastic waste alone. 100,000 marine animals die from getting entangled in plastic yearly – this is just the creatures we find! 1 in 3 marine mammal species get found entangled in litter, 12-14,000 tons of plastic are ingested by North Pacific fish yearly.

No. There is no good evidence that people can get cancer from using plastics. So, doing things like drinking from plastic bottles or using plastic containers and food bags won’t increase your risk of cancer.

Plastic cannot be digested once it had been swallowed and has to be excreted. Unless your dog chews the plastic into tiny pieces it cannot pass through the dog’s intestines/bowel and will cause a blockage. This may take months to cause a problem but once the blockage occurs your dog will die without surgery.

Your stomach’s primary digestive juice, hydrochloric acid, can dissolve metal, but plastic toys that go down the hatch will come out the other end as good as new. (A choking hazard is still a choking hazard, though.)

Charles Breder: “If you were to accidentally eat food containing melted plastic, you wouldn’t suffer any harmful effects to your health, but your food probably wouldn’t taste too appetizing.” We’ll probably continue to use paper towel or plastic wrap in the microwave, but more prudently.

While it’s practically impossible to eliminate plastic from modern life, there are a number of steps you can take right now to cut back.

1. Do: Drink tap water.
2. Do: Heat food in or on the stove, or by microwaving in glass.
3. Do: Buy and store food in glass, silicone, or foil.
4. Do: Eat fresh food as much as possible.

Unless you’re very ill, it’s not likely anyone will be analyzing your poop under a microscope anytime soon. But if someone did, you might be surprised that among the assorted bacteria and waste lurks something a little more disconcerting: traces of plastic.

New study on microplastics in stool raises concerns. There’s a good chance a dose of tiny plastic particles has taken up residence in your gut, a new, small study argues. More than 95 percent of the particles came from plastics used in food packaging and storage.

Constipation. Constipation may be caused by a low-fiber diet and lack of fluids. Fiber adds bulk to stool, increasing its size. If you don’t eat enough fiber or drink enough fluids, stool loses its bulk and may become thin and stringy.
