Microplastics in our food and water can increase the amount of fat we digest and absorb, increasing the risk of obesity, heart disease and other conditions associated with excessive fat intake.
When plastic is broken down by sunlight, water, landfill incinerators, and other processes, it can form microplastics, pieces less than 5 mm long. “As they degrade, they get smaller and smaller, towards the nanoscale,” says Philip Demokritou of Rutgers University in New Jersey. “Nano is…
