Pollution creates a negative externality that affects everyone on the planet to some degree. There are certain communities that are underrepresented and thus the impact could be greater on them. Native Indian communities in the Pacific Northwest in North America are reliant on marine ecosystems in particular. In recent years, aquatic pollution has begun to affect these ecosystems in great amounts. One major source of pollution entering waterways is through storm water runoff from road systems. Much focus has been given toward tire degradation and the leaching of chemicals related to tires into the environment.
