In March last year, I wrote an article about the pervasiveness of plastic pollution in the environment. I was expressing then some frustration at being unable to determine verifiable health impacts on humans of such widespread pollution by plastics, apart from a few known toxic compounds.
A year later, more and more observations about the prevalence of obesity around the world may be providing a clue about the impact of plastic pollution on human health. Obesity around the world has tripled since 1975, and now more people on earth are either obese or overweight than underweight.
