How might the modifications made by Lowell mill owners affect the environment?

The modifications made by Lowell mill owners, such as the extensive use of water power and industrial machinery, often led to significant environmental impacts. The construction of dams and canals to harness river water altered local ecosystems, affecting aquatic life and water quality. Additionally, the increased production and waste from mills contributed to pollution in nearby waterways and surrounding areas. These changes not only disrupted natural habitats but also posed long-term challenges for the environment in the region.
