REF: Impacts of Mans Activities on the Marine Environment (Other (Not Listed) Sample) Content: Course Title:Student's NameInstructor:Date:Dear colleague,REF: Impacts of Man's Activities on the Marine EnvironmentI prepare this letter to present to you the impacts of man's activities on the marine activity. It aims at reinforcing the marine environment policy. Throughout man's existence, people continue to take advantage of the ocean's resources. The result of population increase and global industrialization has been continued threat on these inexhaustible resources. Commercial fishing, oil pollution and spills, ocean acidification, and disregard to the ecosystems continue to present problems to the marine environment.Sufficient researches have been conducted that prove human activities continue to release carbon dioxide into the atmosphere. The world's oceans absorb more than one-third of the emissions from the atmosphere. The carbon dioxide decreases the pH that results in increasing acidity of the sea and ocean waters. The acidification of the waters reduces t he marine biodiversity (Science Learning Hub).Accidents resulting from shipping and transportation of oils across oceans due to man's energy requirements are inevitable. When oil spills occur, they result to devastating effects on the surrounding marine organisms. Sea birds become greasy with the oily water that reduces their ability to maintain buoyancy and body warmth. The organisms that do not drown or freeze to death ingest the oil as they try to clean themselves. The entire marine food web disorganize as the oil reaches different trophic levels (Lerma matson n.d.).Another challenge to the marine environment results from fishing activities. While in the process of fishing, untargeted marine species are netted and killed. Seine netting, trawling, and drift are some of the fishing methods that lead to large quantities of by-catch. The species are no loss to the fishers but are valuable to t...
