An Analysis of Why Lake Michigan is Turning ‘Green’<\/h2>\n

The water in Lake Michigan is much more than just a picturesque and inviting natural resource – it is a vital part of the Great Lakes system. Unfortunately, in recent years it has been subject to an alarming environmental change – the presence of a mysterious and troublesome green coloration. The discoloration has raised significant concern about what is causing the lake to shift to this unnatural hue. In this article, we will explore the scientific causes of this phenomenon and evaluate the effectiveness of measures already taken to rectify the problem.<\/p>\n

At the heart of the issue is a concentration of algal blooms due to increased levels of nitrogen and phosphorous entering the lake. While both of these elements are necessary for life, in excessive concentrations they become pollutants, hindering the balance of photosynthesis and creating an environment where chemical and biological imbalances can occur. In some cases, these imbalances can lead to adverse effects on aquatic life and ecosystems. The elevated levels of nitrogen and phosphorous are largely attributed to industrial activities such as sewage and agricultural runoff.<\/p>\n

Invasive species are also playing a role in the problem. Invasive species can disrupt the natural ecological balance by outcompeting native species for resources or by introducing disease or predation. In the case of Lake Michigan, the most notable invaders are the Zebra and Quagga mussels which have drastically altered the make-up of the food web as well as reducing levels of sedimentary nutrients.<\/p>\n

The damage created by the nutrient surge and the presence of invasive species has been compounded by the effects of climate change. Warming waters are causing increased straining of the lake’s natural flora and fauna and leading to longer algal blooms. This has resulted in the lake becoming oversaturated with oxygen, creating an environment that is conducive to the growth and proliferation of the green algal blooms.<\/p>\n
