I would say there is an important relationship between microplastics and PFAS.
Microplastics can often transport PFAS through the environment. Often, how we see that is by accumulation occurring within fish, which is when we can see that consuming a serving of freshwater fish can expose you to as much PFAS as you would consume drinking a month's worth of contaminated drinking water. This is an interesting analogy in that, as plastics become invisible, they also create a much bigger toxics problem, being a vector for transporting these substances in our environment.
I'll defer to our colleagues about the climate piece, if they want to refer to it.
