 It's raining plastic. Microplastics have been found in our blood, our lungs, and now it's falling from the sky. And the worst part? Plastic never goes away. It just gets broken down into smaller pieces, blowing all around the world in a never-ending cycle. It's so bad that microplastics from Europe are landing in pure habitats like the Arctic. Even deep-sea ecosystems aren't safe. And the numbers are shocking. Researchers found that 98% of air and rainwater samples they collected from 11 national parks all had microplastic particles. So it may be invisible, but it's definitely all around us.
