Yes, even though the Great Lakes are rather massive, they still are susceptible to pollution. This general fact sheet on the Great Lakes (http://www.epa.gov/glnpo/factsheet.html) provides an excellent explanation to your question:
"In spite of their large size, the Great Lakes are sensitive to the effects of a wide range of pollutants. The sources of pollution include the runoff of soils and farm chemicals from agricultural lands, the waste from cities, discharges from industrial areas and leachate from disposal sites. The large surface area of the lakes also makes them vulnerable to direct atmospheric pollutants that fall as rain, snow, or dust on the lake surface, or exchange as gases with the lake water."
I hope that helps!
yes all lakes get polluted
It has become polluted.
Since the clean water act was passed, the Great Lakes have been returning to a less polluted condition. Before the Act was passed, environmentalists had estimated that it would take 150 years to make the lakes habitable for fish again. It took about 15 years. You still ought to think twice about eating fish from the lakes, but the Earth is amazingly resilient if we give it a chance to heal the damage done.
Well littering can casue a polluted lake
Yes, because when other lakes or ponds get polluted and the clouds condenses it, it will rain polluted rain into the ocean.
it's very huge Together, they form the largest group of freshwater lakes on Earth. That seems pretty special, right? ^ Dont know who wrote that BUT Though that is true, the great lakes are all polluted to the point that the aquatic life and the land suffer.... and people still fish in the lakes.
They look very merkie
It rains then washes the fertilizer from farms and into the lakes.
Because what may be "polluted" to humans can be the ideal environment for some plants and animals to thrive.
Estimating the exact number of polluted lakes worldwide is challenging due to varying definitions of pollution and differing assessment methods. However, studies indicate that millions of lakes are affected by pollution, particularly from agricultural runoff, industrial discharges, and urban waste. In some regions, up to 40% of lakes may be considered polluted. Ongoing monitoring and research are essential to address and mitigate this issue effectively.
