Natural stream purification processes require adequate oxygen levels in order to provide for aerobic life forms. (Oxygen Saturation) As dissolved oxygen levels decrease, the aquatic life is put under stress. The lower the concentration is, the greater the stress. Oxygen levels below certain levels can result in large fish kills. Dissolved oxygen is absolutely essential for the survival of all aquatic organisms, and thus these two variables have a definite relationship with another.
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. Beyond the macro-dynamics of the giant emergency reservoir that Herb Mills spoke of , and wetlands being an immensely productive nursery for the seafood that we eat, individual species that
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.
An ecosystem is the interaction between abiotic and non-abiotic components of an environment as a functional unit.. The vulnerability of an ecosystem is determined by four main factors, these being Biodiversity, Extent, Location and Linkages. The level of fragility within an ecosystem is determined by the extent of natural and human induce stresses, increasing disruption of an ecosystem can lead to higher levels of vulnerability and reduced resilience. An ecosystem that demonstrates vulnerability is the Daintree Rainforest, the wet tropics have been subjective to heavy logging and agricultural clearance as well as being exposed to climate change as well as being an extremely old ecosystem, leaving the Daintree in a particularly vulnerable position. Biodiversity is highly important when determining the vulnerability and resilience of an ecosystem as species, genetic and population diversity can have detrimental effects on the ability of an ecosystem to survive and recover after damage.
These ecosystems provide important links between land, freshwater and marine environments, as well as feeding and breeding grounds for many marine species (Great Barrier Reef Coastal Ecosystems). Any changes to or loss of these coastal ecosystems from human actions disturbs the ecology of the Great Barrier Reef. The framework of the reefs is formed by coral polyps that live together in colonies inside the coral. Besides the polyps, small fish and other organisms use the Reef as protection from predators. However, coral coverage on the Reef has fallen nearly 50% between 1985 and 2012 (Great Barrier Reef).
Hayes argued, “the impacts of atrazine on amphibians and on wildlife in general are potentially devastating” (Hayes et al. 4). Atrazine causes disease and deformities and is a threat to both humans and wildlife. Atrazine is the most common pesticide contaminant of ground and surface water that can spread a half million pounds of atrazine more than 1,000 km from the point of application via rainfall (Hayes et al. 1).
In contrast, minerals might be absorbed not only from diet but also from the ambient water in developed fish. Fatty acids are one of the most important nutrients for most finfish species, and supplementation of dietary fatty acids improves survival and growth for marine fish larvae. Copper is one of the essential trace minerals, which plays an important roles within the activity of enzymes as well as within the metabolism; however, copper deficiency in the diet and ambient water reduce the growth rate of the fry considerably. There were two experiments tested and for which material and methods were such as wild adult pair of anemonefish, water temperature, and tanks. Experiment one was based on the effect of the copper on survival and growth of the fish which were examined under the semistatic condition with six different copper concentration.
Copper (II) sulfate is toxic to fish, and must be used wisely when eradicating pesky snails and fish parasites. To protect our water pipes, we use Copper (II) sulfate to keep evasive water plant roots at bay. This special Compound is also a helping hand in organic synthesis, reacting with potassium permanganate to make an oxidant for primary alcohols. At one point in the medical field Copper (II) sulfate was used as an emetic, which made a patient throw up immediately after consumption, but is now regarded too toxic for this use. The most interesting use most would say, is the way Roger Hiorns used 75,000 liters of Cu(II)SO4 to fill an apartment, and left it to solidify for many weeks.
One of the main problems of groundwater abstraction is in coastal areas, namely salt-water intrusion. This is the movement of salt water into an aquifer that previously held fresh water. Salt-water intrusion is sever along the Mediterranean, Black Sea and Baltic coasts. Tundra landscapes hold vast quantities of the worlds freshwater as permafrost. Changes in temperate and the melting of permafrost can have significant impacts on the availabity of water.
The unbalancing of nature has led to many situations where humans have endangered themselves by creating unsustainable environments. Case in point is the overfishing of lakes which unbalances the ecosystem by removing fish which provide other animals with sustainability. This scenario has played out repeatedly. Science and technology has offered many solutions to these problems and especially when concerning animal rights. Today it is possible to restock lakes with fish and by controlling periods of hunting animals is not driven downward in population to dangerous levels.
