Why is it so hard to make a biodegradable plastic? Are so-called compostable plastics the answer?
“Biodegradable” means that biological organisms, like bacteria and fungi, break something down until there’s nothing left but carbon dioxide (CO2), water, and something called biomass (natural material from living things). Learn more about the challenges of making a truly biodegradable plastic.
Can Avoiding Plastic for One Week Reduce the Level of Toxic Chemicals in Your Body?
A new scientific study published in Nature Medicine found that just seven days of living with less plastic significantly reduced levels of chemicals used to make plastics in our bodies. Learn more.
Why Do We Need to Take Extra Precautions to Protect Children?
Children are uniquely vulnerable to toxic chemical exposures for a number of reasons. Find out what they are and why it’s critical to take extra precautions to protect their development and health.
Why Does Black Plastic Pose a Bigger Risk Than Other Colors?

Does Plastic Impact Our Hearts?
Some microplastics are tiny enough to pass through the lungs or gut and enter the bloodstream, where they can travel throughout the body and accumulate around the heart. An 2024 study in the New England Journal of Medicine provided the first evidence in humans that directly linked microplastics to heart damage. Learn more
How Does Plastic Affect Our Hormones?
