Discovery of Plastics' Impact
In the late 1990s, a researcher observed unusual behavior in the chromosomes of mouse egg cells, which led to the discovery of the harmful effects of degraded plastics in their environment. Initially, all seemed normal for the mice until changes were noticed in their cages, which were impacted by the incorrect use of a detergent. This mistake led to harmful substances leaching from the plastic into the mice’s bodies, disrupting hormonal balance and affecting egg cell development. The incident highlighted a significant issue with plastic materials that had largely gone unnoticed at the time, setting the stage for ongoing concerns regarding plastic safety and its effects on health.
