The types of pollution in the Great Lakes has human activity caused are:
sewage disposal
runoff
air pollution

[Deleted]

The types of pollution in the Great Lakes that human activity has caused include:

1. Sewage disposal: Human activities, such as improper sewage disposal or wastewater treatment, can introduce contaminants, pathogens, and excess nutrients into the Great Lakes. This can lead to water pollution and eutrophication, causing harmful algal blooms and impacting aquatic ecosystems.

2. Runoff: Human activities, including urbanization, agriculture, and industrial practices, can contribute to non-point source pollution through runoff. This includes pollutants like sediment, fertilizers, pesticides, heavy metals, and other chemicals that can enter the Great Lakes via stormwater runoff, negatively affecting water quality and aquatic life.

3. Air pollution: Human-generated air pollution, such as industrial emissions and vehicle exhaust, can release pollutants into the atmosphere. These pollutants can then be transported by air currents and deposited into the Great Lakes through precipitation or atmospheric deposition. This can introduce contaminants, including toxic substances like mercury, into the lake ecosystem.

Therefore, the correct options are sewage disposal, runoff, and air pollution.

Sources of pollution include:

1.) runoff of soils and farm chemicals from agricultural lands
2.) waste from cities
3.) discharges from industrial areas
4.) Leachate from disposal sites
5.) direct atmospheric pollutants that fall as rain, snow, or dust on the lake surface, or exchange as gases with the lake water
