Answer:
Microplastics are tiny plastic particles measuring less than 5mm in length that are increasingly becoming a cause for concern in the environment. These particles come from a variety of sources, including the breakdown of larger plastic items, synthetic fibers from clothing, and even from personal care products. While microplastics are a growing issue in oceans and other bodies of water around the world, they are also a significant problem in the Great Lakes region. As one of the largest freshwater systems in the world, the Great Lakes are a vital resource for the communities and wildlife that depend on them. However, the presence of microplastics in these lakes poses a serious threat to their health and ecological integrity. In this essay, we will explore the impacts of microplastics in the Great Lakes, the sources of these particles, and the actions being taken to address this pressing environmental issue.
