Coral reefs are dying at an alarming rate thanks to many factors, mostly caused by humans. For instance, when we pollute the earth and our oceans by burning greenhouse gases, we cause climate change. This affects the coral as they can’t withstand the water raising by only a few degrees. This often causes coral bleaching, which kills these animals. Also, storms can destroy reefs, also often caused by humans affecting the environment.
The gooey mass that makes up an oil spill will litter the shoreline with a monstrous dark tar making it exceptionally hazardous since the shoreline is the place much marine life is concentrated. Shorelines give nurseries to fish and marine life, by defiling the shoreline the oil have a risk and are hazardous to the marine life in the
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
These signs show that the bank systems are important for the FKNMS for providing a structural support and high productivity for the biodiversity. Exploitation of these essential fishes and pollution of the water could greatly destroy the bank systems and cause a rippling effect among the ecosystem. Knowing how important these bank systems are, they should receive additional protection through management zones. New management actions will help protect fish and stocks, to ensure the stability of recreational and commercial fisheries. To ensure a higher water quality and sustainable habitats, anchoring activities and vessel discharges will be restricted in the management zones.
Dead zones are oceanic areas where there is a depletion of oxygen levels and often have no living organisms. In fact, according to the National Oceanic and Atmospheric Administration (NOAA) “ The second largest dead zone in the world is located in the U.S., in the northern Gulf of Mexico” (US Department of Commerce, National O...). They are caused by pollutants such as oil and fertilizers which can cause an overgrowth of algae. The overgrowth of algae blocks sunlight from the plants underwater, disrupting the photosynthesis process. As a result, the food chain is disrupted because the producers at the bottom of the food chain cannot produce because sunlight is blocked, leading the primary consumers without a source of food.
As people have to be hired to clean up, and people not wanting to go to dirty beaches. Cost money to people working at the beach.This problem doesn’t just occur in the Persian Gulf, it occurs world wide. A study from the university of Georgia, February 3rd 2015, claims that about 8 million metric tons of plastic trash enters the ocean every year. Pollution in the Persian gulf is negatively impacting marine life, as oils spills occur, and ocean mining is at it’s peak, but most importantly sewage dumping. Believe it or not we are all a witness of watching someone litter, or us littering.
El Niño’s have been occurring for about 10,000 years since the last Ice Age. When an El Niño occurs it decreases the rise of cold water off the coast of the Americas. “When this happens the fish either die or migrate into areas that they will find more to eat” (wildlife.ca.gov). When this happens in the in the Pacific close to the Ecuador the Galapagos fur seals struggle to find food. When the fish are gone the wildlife that depend on them for food will die also.
Many of the world’s problem stem from a lack of clean and sustainable drinking water for all. Though it may seem like a small fraction of 65 million, over 840,000 die because of a lack of clean drinking water. Before trying to fix this pressing issue, we must first understand the problem, answer the question as to why it is a problem, and then create solutions that will actually work. “Around the world about 750 million people lack access to clean water, that is about 2 and a half times the United States
Human undertakings have the unfortunate side effect of causing Mississippi River sediments to go straight down the river's channel and into the Gulf of Mexico (Farber 147). Human reformations in Louisiana’s coastal wetlands also include draining and filling for urban or agricultural expansion, which contribute to the premature and accelerated loss of
Additionally, temperatures have dropped by a bit less than 1°C because of clouds forming, limiting the amount of sun reaching to the ground . These effects come from the lake effect which is when warm and moist air evaporates from the river and mixes with cold and dry air, causing precipitation. Furthermore, the dam has also created drought problems as water levels have been reduced in the river. In 2008, the river dropped the most it has ever dropped in the past 142 years and the year of 2011 was considered to have the worst droughts in 50 years. This caused problems in farms as it meant that there was no water for livestock, causing a problem with food production.
One of the reasons that most colonist died was that they didn’t have enough food and water to survive. They had to dig wells to look for water. They had streams with fish but they only had an abundance of them in the Summer and Spring. They needed more food gatherers and hunters to have more success. Also Jamestown had gigantic drought while they were there and with not enough water, there aren’t going to be very many crops for the colonist to eat.
The effect of agricultural runoff in the Chesapeake Bay watershed It is almost impossible to turn on the news without hearing about the turmoil of pollution, and how it is negatively affecting life worldwide. But have you stopped to think about how pollution is directly affecting your daily lives? Water is the heartbeat of all life, and without it nothing could thrive. Odds are, if you live within the northern mid-atlantic you get some or all of your water from the Chesapeake Bay, or one of its watersheds. Years of agricultural runoff from large industrial farms has lead to contamination of the Bay, endangering not only the lives of the wildlife, but also our own.
However, it 's not only just because of man-made reasons. The coastal marshes disappearing can also be affected by natural causes. Sediment is being deposited into a river delta increasing the weight, which causes the entire area to sink (p. 11). Depositing may sound like a positive cause, but however if the course of the sediment changes then no new sediment will continue to be deposited. Another natural cause is oceans and hurricanes.
