The expansive scale of Lake Superior makes it a major contributor to the world climate and environment. Because of its large size, Lake Superior is one of the largest sources of freshwater in the world, and is home to a wide variety of species of plant and animal life. As a result, environmentalists and conservationists have been working hard to protect the lake and the surrounding region for years.

The Impact of Urban Sprawl on Lake Superior

The growth of urban areas in the US and Canada can have a negative effect on Lake Superior due to increased runoff from these areas and the potential for pollutants flowing into the lake. As a result, there have been several conservation efforts to try and minimize the impact of urban sprawl on Lake Superior.

These efforts include measures such as discouraging the development of waterfront property, limiting sewage discharge into the lake and surrounding rivers, and increasing public access to the lake. Additionally, conservation groups have worked to preserve open space and land adjacent to Lake Superior.

The Great Lakes Commission and several other public agencies have programs to conserve and protect the lake by monitoring the levels of pollutants and by providing the public with information about its health.

Commercial Fishing in Lake Superior

Commercial fishing plays a critical role in the economic life of Lake Superior. The lake provides a livelihood for many fishermen who harvest a variety of fish species, including salmon, whitefish, trout, and sturgeon.

Fishing in the lake is strictly regulated by both the US and Canadian governments, so as to ensure the sustainability of the fish populations. Additionally, there have been several successful efforts to restore fish populations, such as the reintroduction of the Lake Trout and several conservation efforts to limit the spread of aquatic invasive species.

Fishing on Lake Superior provides an important source of revenue for many of the communities on its shores. This revenue goes towards supporting economic development, recreational activities, and the preservation of natural resources.

The Cultural Significance Of Lake Superior

Lake Superior has had a long history of cultural significance for the native people who lived on its shores for thousands of years. These cultures have seen the lake as a source of sustenance as well as a spiritual connection to the environment.

Lake Superior’s cultural heritage is reflected in its folk traditions, art, and literature. It is also home to various public monuments, parks, and trails, many of which are accessible to visitors.

Environmental Challenges Facing Lake Superior

Lake Superior faces a variety of environmental challenges such as climate change, invasive species, overfishing, and air and water pollution. As a result, many conservation efforts have been undertaken to try and protect the lake and its surrounding environment.

Climate change is a particular concern for Lake Superior and its surrounding environment. The lake’s large surface area makes it especially vulnerable to changes in temperature, as warmer temperatures can lead to increased evaporation and more severe seasonal weather patterns.

Invasive species, such as the zebra mussel, can have a negative effect on the lake’s ecosystem by disrupting the food chain, competing with native species for resources, and introducing diseases. Overfishing is also a problem, as it can put the lake’s native fish populations at risk.

Water and air pollution also pose a threat to Lake Superior’s environment. Many of the cities on its shores are sources of industrial and residential runoff, which can contaminate the lake. Additionally, major highways like the I-35 and I-94 are major sources of air pollution to the lake.

Restoration Efforts To Protect Lake Superior

Many organizations are working to restore and protect Lake Superior and its surrounding environment. These organizations work to monitor the lake, limit pollutants, and promote public awareness of the lake’s vulnerability.

The Great Lakes Commission and International Joint Commission have programs for protecting the lake and promoting its health. Additionally, the Lake Superior Research Institute in Wisconsin is conducting research to better understand the lake’s environment.

There have been several successful efforts to limit pollution and restore fish populations in Lake Superior. These include the reintroduction of the Lake Trout and several conservation efforts to prevent the spread of invasive species. Public awareness initiatives and educational outreach have proven to be particularly effective in engaging the public in efforts to protect the lake.


Lake Superior is one of the most impressive natural wonders in the world, boasting an area of over 31,700 square miles with a diverse array of landforms, species, and economic opportunities. In order to protect this delicate environment, many conservation and restoration efforts are underway. With greater public awareness and understanding, Lake Superior will no doubt remain a source of pride and natural beauty for many years to come.
