Ever heard of tiny plastic bits floating in the air? Surprisingly, they're everywhere! From worn-out tires to decomposing trash, these microplastics are making their way into our bodies. Recent research suggests they might be behind some serious health issues like infertility, colon cancer, and breathing problems. These microplastics are smaller than a grain of rice and can come from many places, like cosmetics, toothpaste, and broken-down plastic items.

Scientists from UC San Francisco studied over 3, 000 reports and found that these tiny particles could harm our reproductive, digestive, and respiratory systems. They even linked them to colon and lung cancer. Dr. Tracey Woodruff, who led the study, explained that microplastics are like tiny bits of air pollution, which we know is bad for us.

But where do these microplastics come from? One major source is the wearing down of car tires on roads. Each year, companies worldwide make nearly 460 million metric tons of plastic, and that number is expected to rise.

You might be wondering if these microplastics are in your body. The answer is yes! They've been found in human placentas, lungs, liver, urine, breast milk, and blood. Researchers also found strong evidence that microplastics can harm sperm and testicular health, and weaken the immune system.

The study calls for more research to understand the full impact of microplastics on our health and how to reduce our exposure to them. The findings were shared in the journal Environmental Science & Technology.
