How the oceans may die is crucial to understand in order for them to be preserved for the survival of the planet. Numerous human activities generate a staggering amount of grave complications for the oceans and its crucial marine life. One of the most direct human activities that causes rapid decline in marine populations is overfishing. Some of the species
This leads to the ultimate death of the coral and the homes of many sea creatures. Coral bleaching is a problem that occurs worldwide where scientists are trying to uncover the central causes of the bleaching and how it affects people and the environment. Scientist have conducted multiple
Corals under stress due to changes in PH levels or temperature of the water will expel the algae (zooxanthellae) living within their tissues causing the coral to turn completely white. This is called coral bleaching. Another cause of coral bleaching is produced formation water, an effluent of offshore oil and gas industries that cause significant bleaching ( White et al .2012) .When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality. Mortality amongst corals has appeared to be the breakdown of the symbiotic association between the zooxanthellae and the coral host.
Scientist’s observations in 1961 shows that the temperature of the global ocean has on average increased even at three thousand meters, as well as the observation that the ocean has been absorbing more than eighty percent of heat that is added in to the climate system which causes the sea levels to rise and creates an issue for the islands that are at sea level. The name ocean acidification is the ongoing decrease in the pH level of the earth’s oceans which causes their uptake of human activity carbon dioxide from the atmosphere. However, the oceans natural absorption of carbon dioxide helps decrease the climate effect of human activity with the carbon dioxide emissions which is believed in the decreasing pH level which makes the water acidic, then later has a negative effect on the oceans creatures which kills the coral reefs. “Coral bleaching occurs when the symbiosis between corals and their symbiotic zooxanthellae breaks down, resulting in the loss of the symbionts and a rapid whitening of the coral host (thus the term "bleaching")” (The International Coral Reef Initiative). Coral bleaching is a stress response by the coral reefs which is caused by many reasons, but the most important and frequent cases is the rising sea
The primary consumer only obtains around 10% of the producer’s energy as they may not eat the whole entity or energy might be lost through waste. The population of the largest and most significant vertebrate plants feeds, including sea turtles, dugongs, have been severely decimated by the impacts of humans on the reef. The loss of these vital animals has and will more severely disturb the coral reef food web in a significant manner, although the specific impacts are not clear
This initiative should be considered by all governments as soon as possible in the hopes of saving the endangered sharks. Otherwise, without sharks, the ocean biological system will be unbalanced, thus affecting the entire food chain. If the populations of planktons or other small creatures increase, consequences will follow. The control and management of the oceans will be tougher if the population of small fishes were to greatly increase. The outbreak of diseases in the ocean will be induced and this may spread to rivers and lakes which will ultimately affect us since our drinking water would become
“Our globe is under new dramatic environmental pressure: our globe is warming, our ice caps melting, our glaciers receding, our coral is dying, our soils are eroding, our water tables falling, our fisheries are being depleted, our remaining rainforests shrinking. Something is very, very wrong with our eco-system” (Lamm) It may seem very overwhelming on where we should start to help our environment since it seems like such a big task. One small place that we can start is with helping our bleached coral which can help the whole state of our
Keeping the Ocean Free of Debris Pollution in the Persian gulf is negatively impacting marine life How much are we trashing our ocean? CNN, February 12th 2015. Arabian Gulf coral reefs dying a slow death. Gulf news, June 10th, 2014. Spill, Dolphin Deaths Spark Alarm At Persian Gulf Pollution.
Imagine the very thing which keeps you alive is drained from you. This is what coral reefs around the world endure each day. Due to both human and environmental factors, coral reefs are dying out at an alarming rate but just because they have become bleached, that does not mean an absolute death sentence to the reed. If you have ever been on a beach trip, you have more than likely seen and/or explored a coral reef. You have seen the beauty that they are capable of holding and all of the life that they support.
Negative Effects of Ocean Pollution “Each day, oil used to lubricate engines and to power the vessel leaks into the ocean” (Wroble 44). When the residue enters the ocean, it begins to affect the environment and animals. This is just one of the many problems from ocean pollution. “According to Worldwatch research associate Peter Weber, 80 to 90 percent of all of the materials dumped at sea are dredgings...dredgings are rich in toxic chemicals...from nonpoint sources” (Wroble 49). One particular chemical that affects the oceans are Polychlorinated Biphenyls, or PCBs.
