However, coral coverage on the Reef has fallen nearly 50% between 1985 and 2012 (Great Barrier Reef). This is due to poor water quality caused by human development in Queensland which affects the health,
Clown fish are so heavily dependent on the reefs due to the fact that the anemone live only in these areas. Increases in the acidity level are another detrimental factor coming from the global climate change. This inhibits the clown fish's ability to detect chemical signals that
More than 1 billion people worldwide lack access to safe drinking water (Lawrence & Weber, 2011, p. 43). Especially in the developing countries, with poor water management it contributes to increasing malnutrition and disease, a losing of biodiversity and agricultural production, rising food prices, reducing economic growth and social stability, that leading to conflicts over water resources. The major source for of the Coca-Cola Company’s (TCCC) products is water. Even the company’s CEO admits “that unless the communities where the company operated had access to water, they haven’t got a business” (Lawrence & Weber, 2011, p. 43). Coca-Cola and its bottlers using 80 billion gallons of water every year worldwide; in which two fifths goes into finished beverages.
For example, in 2008 the government permanently closed 60 square miles of the bay to fishermen to protect wildlife. This shows that Lyme bay plays a huge part in the south of England’s economy. On top of the human damage, Lyme bay is located on an actively eroding piece of coast.
They must be valued and protected. 1) The alarming losses to our fishing economy, the declining catches of menhaden and other commercial and sport fish, and the pollution and silting caused by dredging, all point to the need for preserving these meadowlands and watercourses. 1) Over the years, beach erosion has been a subject of concern, and their protection a major expense to national, state and local governments. The continued diking and filling of marshes from Sandy Hook to Cape May contributes essentially to the destruction of our valuable coastal resorts. We must save our taxpayers multimillions of dollars in beachfront expenditures by saving wetlands as a natural safeguard and reservoir in times of emergency.” B) In addition to being a massive source of flood control, and water purification, the wetlands are the “nursery” to hundreds of species of fish and shellfish that sustain mankind.
The areas in the greatest decline are Central America, the Caribbean, and Australia. The three primary causes for the frog decline are habitat destruction, global climate change, and a new emerging disease called chytridiomycosis (chytrid). Frogs have been given very little concern as we develop new roads, build homes, cities and industries. As a result of these cultural developments, we are destroying the frog’s habitats worldwide. Global warming and climate change have been given a lot of attention and discussion worldwide and most likely has had a significant negative effect on the frog.
It generally takes at least three kilograms of feed to produce one kilogram of salmon. The shrinking of the numbers of prey species threatens the entire food chain, putting further stress on large predator stocks. Depleting fisheries also negatively affects the economies of developing countries, home to nearly 60% of the world’s fishers that are classified as small-scale commercial or subsistence fishers. In Africa, an estimated 100 million people depend on fish from inland sources, such as lakes and rivers, for income as well as protein and much-needed micronutrients like vitamin A, calcium, iron, and zinc. But coastal fisheries across West Africa have declined by up to 50% in the last 30 years due to significant pressure from large industrial fleets.
Aquatic invertebrates are also affected by gas bubble disease but at levels higher than those lethal to fish. In recent years, it has come to the understanding to many scientists that oxygen depletion is the most common cause or fish kills in ponds and lakes. (Why Oxygen) As can be seen, environmental oxygenation can be important to the sustainability of a particular ecosystem Thus, it is essential to explore how the amount of dissolved oxygen can impact aquatic life in a system. This experiment is a replication of Biosphere 2 in the early 1990s. It is a closed ecosystem that is artificially constructed to be self-sustainable.
This pollution has since affected their health and has resulted into more cancer deaths, miscarriages, defects in births, dying of livestock and the sick fish. The attempts to solve the problem and prosecute those involved have proven futile since the county‘s judicial system is marred by corruption. The company was required to clean up its mess and pay for the damages. The toxic waste dumped in the area is believed to be of an estimate of 18 billion gallons, and its remains are still present to date.The company that took over the ownership from Texaco was later ordered to pay eighteen billion dollars for the damages. This was to act as the reparations for the
Both cause population within the water system. Agricultural Usage Using the ocean water for drinking of livestock and human usage. In 200 to 300 words, respond to the following: Choose one fresh or ocean water resource challenge and describe in detail why the issue has become a problem and how human activities have contributed to the problem. Water population has become a problem that seems to be out of control and we are running out of time to fix this problem. It is a problem because the level of water population we have now can kill the animals within the water.
