Plastic waste is a huge problem because it lasts for centuries. To help fix this, scientists found that waxworm caterpillars can eat and digest plastic bags in just one day! These tiny "plastic-eaters" turn trash into body fat, breaking it down much faster than nature ever could. This creates a smart cycle where worms destroy pollution and then become a healthy snack for farmed fish. It is a "double win" that cleans our Earth while also making a sustainable food source for animals.
