Are the microplastics found in the environment coming from corporations production residues or from people’s consumption residues ? I would say a relevant part of them comes from individuals. If you believe the issue is important enough, then raising awareness is the right direction so they take healthier choices. However most of the worlds population lives in developing countries, and microplastics are very low in their list of priorities, their top priority is actually making to the end of the month with enough food, shelter and some medical care or even education for them or their kids. Blaming everything on greedy corporations is a very superficial analysis.
