What people fail to realize when it comes to environmental concerns, coal is not the only one in existence. Dams, natural disasters, and endangered species are also considered to be major concerns in our environment. Recently I conducted research concerning these specific issues through reading scholarly reviewed articles and studies over the internet just to see in what way they portray environmental concerns to our environment and how big of a risk they contain. What makes this study significant is because of the fact that everyone should be aware of not just one but all of the hazardous risks that is present in our environment. People should be aware of how Dams effect our water impact, endangered species are affected tremendously in our environment, and natural disasters put the lives of every living organism in our environment at …show more content…
Downstream of dams, marked changes in fish populations occur as a consequence of blockage of migration routes, disconnection of the river and floodplain, and changes in flow regime, physiochemical conditions, primary production and channel morphology(McCartney, 2009, pg. 128). Due to the changes in the fish population caused by dams, the 1996 International Union for Conservation of Nature (IUCN) Red List of Threatened Animals includes 617 freshwater fishes (McCartney, 2009, pg.128). Fresh water fish is not the only species being affected by dams. According to the article “Living with dams: managing the environmental impacts” written by Matthew McCartney, “The most negative downstream consequence of river regulation caused by dams on mammals and birds is the disruption of the seasonal flood regime along the river” (Nilsson & Dynesius, 1994). How the flooding regime being altered effects the birds and mammals, is the changes in vegetation may place the birds and animals that depend on it at risk. All of these reasons are what makes Dams a concern to our
