It is a very good question that is very hard to answer, but we will try. The biggest reason is that the pollution is very connected with the filth of our planet. The polution is killing lots of animals and plants and it means that we can also run out of food, and even that food is poluted by microplastic, that then starts stacking up in our bodies. I don´t know about you, but I don´t want to eat purified food or get microplastic stacked in my body.
