1. Describe a human-induced environmental impact and how knowledge of ecosystem ecology could be used to mitigate this impact. In your answer, pay particular attention to the spatial and temporal nature of the impact and how this has affected ecosystem structure and function. There are many factors that can cause harm to the environment. Some of these impacts on the environment may be caused by natural factors for example, fires, floods, hurricanes, tornados, etc. Unfortunately, there are many instances in which humans have somehow managed to cause great harm to the environment through incorrectly discarding trash so it ends up in our oceans, overpopulating areas which can lead to land damage, and of course pollution. However, the human-induced environmental impact I really want to focus on here are oil spills. In 1989, a spill by Exxon Valdez caused 750,000 barrels of oil to be released into the water in Prince William Sounds, Alaska. This spill has been known to be one of the worst human-induced environmental disasters. As a result of the spill, up to 250,000 seabirds, 247 bald eagles, 300 seals, 2,800 sea otters, 22 orcas, as well as a large number of salmon and other fish who resided in these waters were killed. Another oil spill which occurred on March 16, 1978, has been known to be one of the largest oil spills recorded in history. It was also known to have been the oil spill that caused the largest number of deaths among marine life. The ship carrying the oil was
