Clearcutting has a number of harmful effects on Canada's environment. One of these effects is that it changes the flow of rivers. When trees are removed on a large scale, it can alter the natural water retention and filtration systems that forests provide, leading to changes in river flow patterns and disrupting aquatic ecosystems.

Additionally, clearcutting can cause erosion. Without the tree roots holding the soil in place, rainwater can wash away the topsoil, leading to soil degradation and loss of productive land.

Clearcutting can also result in the pollution of farmland. Pesticides, fertilizers, and other chemicals used during reforestation and logging operations can contaminate surrounding agricultural areas, impacting soil quality, water sources, and the health of crops and livestock.

Furthermore, it can lead to the seepage of toxic waste into groundwater. Clearcutting typically involves the use of heavy machinery and the application of chemicals, which can result in the contamination of groundwater sources with pollutants if proper measures are not taken to prevent it.

Overall, clearcutting has significant negative environmental impacts, including altered river flows, erosion, pollution of farmland, and the potential seepage of toxic waste into groundwater sources.
