I could see microplastics being the next thing that governments and industry both try to tackle. However, there is not a lot of research out there about how to tackle this issue and alternatives that make cutting down the amount of microplastics ingested economically viable.
Given the sheer amount of microplastics consumed by individuals and how they have been found throughout the human body it is a place that is going to require a ton of research. This research will likely have to come from the Federal Government given that it really does not have any monetary value to companies.
According to one estimate, every American consumes between 39,000 and 52,000 microplastic particles every year.They then accumulate inside our body. Studies have found microplastics in human brains (roughly the amount in a heaping teaspoon of table salt), as well as in our stomach, lungs and bones. Researchers have linked microplastics with a higher risk of stroke, inflammatory bowel disease and dementia.
