Great lakes have played a significant role in the economic development of the eastern part of the United States and Canada. Today, a large number of inhabitants and huge capital are concentrated here. The economy is divided into the primary, secondary and tertiary-quaternary sectors.
Primary sector – Agriculture
Agricultural land is the biggest “attraction” for immigrants in the Great Lakes Region in the 19th century. Then there was mass migration, there came 400,000 people in Michigan, 300,000 million in Wisconsin and perhaps half a million in Upper Canada. Due to fertile soil, milk and meat production has become dominant in agriculture. As time passed, the population began to grow, and then specialized in growing crops such as fruits, vegetables, tobacco, hook rose, wheat and soybeans. These crops are the primary crops in the Great Lakes region. The northwestern part of the region, Michigan, is known for its cherry production. Channels enabled the export of merchandise. Wheat and corn were the first agricultural crops that were intended for export in this way. Large silos and the mills were built on tributaries that were poured into the lakes. As the population grew, meat production for local consumption began to dominate the Great Lakes agriculture. Most of the land is suitable for fruits, vegetables and tobacco. The intensive development of agriculture has also contributed to the pollution of the Great Lakes mainly by eutrophication. The fertilizers used were pumped into the lakes and stimulated the growth of algae and other aquatic plants. As the plants used the oxygen, this led to the lack of oxygen for fish, and this led to ecosystem disruption. Modern monocultural agriculture in large measures relies on chemicals for pest control. These chemicals are mostly synthetic and organic, they find the way to the river and the lake and affect the plant and animal world and endanger the health of people. Pesticides are also toxic, although they are still banned, they remain in the body of the fish.
