Yes, there is already much scientific evidence of microplastic pollution, such as the findings of Professor Richard Thompson (University of Plymouth) who also coined the term. The presence of microplastics in aquatic environments is now recognized as a serious global environmental issue; however, cosmetics are not the only source of microplastic pollution. Most microplastics are the result of the fragmentation of larger pieces of plastic. Other sources of microplastics include the shedding of microfibers by synthetic clothing or microplastic loss from car tires.
