Pollution in the Great Lakes
Transcript of Pollution in the Great Lakes
Fish (ie. Smelt, Trout, Walleye, and Atlantic Salmon.)
Mammals (ie. Black Bear, White Tailed Fox, Moose, Beaver, Canada Lynx.)
Birds (ie. Herring Gulls, Whooping Cranes, Great Blue Herons, Bald Eagles.)
Trees, Algae, Fungi.
Frogs, Turtles, and Snakes.
Populations and Communities
The population numbers in and around The Great Lakes vary from over 170 different kinds of fish, 3500 types of plants and animals, and approximately eight different birds that are native to the area.
The Great Lakes have approximately five communities. There are the forests, dunes, marshes, wetlands, and the lakes themselves. Taking into account all five communities there is such a variety of organisms that the water basin an extremely complicated ecosystem.
In the northern parts of the region there is a dense forest consisting of coniferous and hardwood trees. In the southern area, the dunes, marshes, an wetlands can be found near the many coastlines.
Benthic Invertebrate: these organisms have differing sensitivities to environmental stressors. They give scientists insight on the impact that humans have on the water quality.
Diporeia: are found in abundance across the Great Lakes and with sensitivity to low oxygen levels and some toxic chemicals, it helps diagnose the overall health.

Water Level Fluctuations
What influences unbalance the Great Lakes?
Drainage of natural wetlands and the increasing conversion of forests, open land, and agricultural ground into urban and residential areas is becoming an increasingly worrisome threat. This has depleted wildlife numbers and habitats.
Toxic chemical spills as well as the dumping of heavy metals have greatly decreased the overall quality of the lakes and endangered some animals.
-Acid rain can transfer nutrients and/or toxic contaminants far off course. This can then result in it entering the body of one organism and make it's way through the rest of the food chain.
-Erosion caused by wind and waves poses a constant warning to the entire great lakes region.
-Climate change is also a danger because the warmer temperature decreases run off and increases the amount of evaporation. Already, the lakes provide drinking water for over 40 million people.
-Invasive species that have migrated to the Great Lakes over the years have created competition for habitat and food amongst indigenous animals.This makes it increasingly difficult for native species to reproduce thus endangering multiple plants and animals.
A plant uses sunlight to grow and make their food. abiotic factors, such as, water and the land itself, create habitats for biotic organisms. If there isn't enough of a non-living substance, like light, then the soil will not have enough nutrients and the plants could possibly die.
Climate changes can also create difficulties for plants and animals to survive. Another example is that algae produces food for small organisms. Small fish then eat these microscopic animals, continue to expel carbon dioxide, which plants use to grow. The interaction between living and non living things is vital to the survival of the entire ecosystem.
An ecosystem is the interaction between biotic creatures and abiotic factors in an environment. It can range from something as small as a puddle to the size of an ocean.
