Water Is The Greatest Basic Natural Resources

Spanning lengths over 300,000 meters, this it is a watershed that extends over six states, the District of Columbia, and meets the needs of over 15 million individuals. With its high rate of productivity, its economic and social importance to the surrounding areas, and its close proximity to the U.S. capital, the Chesapeake has the recipient of significant attention for quite some time(Boesch, Donald). One of the issues that threatens this important estuary is eutrophication. For the majority of the 20th century, research, guidelines, and management activity were focused on other issues like wetland loss, over harvesting of fisheries, infectious wastes, etc (Davidson et al, 1997). It took until the final quarter of the century for widespread realization to hit that eutrophication had deteriorated the Bay, with extreme consequences for the Bay’s resources(Malone et al., 1993). After awareness of the impact of eutrophication on water bodies began to increase, when it came to making policies and managing the Chesapeake Bay, eutrophication reduction took precedence over any other issues. As the Bay remains a very important body of water, the significance of understanding one of the major processes responsible for its degradation remains as well. This paper aims to understand the contributing factors of eutrophication in the Chesapeake Bay, with a special focus on the effects of air and

Today, this briefing note is put to you the 'National Taskforce on Environmental Science and Sustainable Development' in response to Urbanisation and its effects on Australias’ waterways. This is fast becoming a critical environmental issue affecting Australia.

Water is the most precious resource to mankind. With every living substance needing water from humans, animals, and plants it is the one thing no living creature can survive without. The thought of losing or having restricted access to water is a very frightening one. Water shortages not only pose an epic threat for the obvious reason, that water is needed, to drink, but also to the lives around us. With little or no water people would have to make hard decisions such as, letting an animal dehydrate so they can have enough water for their families to survive or who they should ration the water to and how much to ration to save as many people as possible. California has been experiencing a very severe drought that has cost California millions of dollars in agriculture and manufacturing due to low water. Though their drought is not apocalyptic yet, but it could worsen and become an apocalypse that we should fear. The changes that can come from such a disaster would change the lives of everyone in society. The ways water shortages could come about is multiple ways such as, drought, poor management of water, or political issues. Water corruption is a threat to society which needs to be dealt with efficiently and immediately.

Let me go all APES here. Water contamination has been an issue across the country. Nutrients like phosphorous, which are found in many fertilizers, can runoff into streams and rivers causing eutrophication. Eutrophication is just a fancy word for these organic nutrients causing a reduction in dissolved oxygen in

In this paper I will examine multiple perspectives in an attempt to understand the recent eutrophication of the Chesapeake Bay. Our textbook, Cambell Biology defines eutrophication as a process in which nutrients, usually phosphorus and nitrogen, are unusually present in a body of water, leading to algae blooms and accelerated growth. Anoxia is a condition in which areas of water are severely depleted of dissolved oxygen.

When talking about nutrient content and nutrient type in bodies of water (especially lakes), three terms help identify these types of bodies of water- oligotropy, eutropy, and dystrophy. Eutropy refers to the probably the best possible condition for a body of water, because this type of body of water has many nutrients available to it (often in the form of silt) such as phosphorous. These bodies of water are usually near farms or forests and are thriving with life. Algae is a common type of organism that grows in eutropy’s, but can serve as a problem for the survival of other species. Oligotropy is basically the opposite of eutropy condition wise. Oligotropic bodies of water usually have a small amount of organic matter, few nutrients, and especially lack phosphorous. These water bodies are often near terrestrial ecosystems. Dystrophy refers to the condition in bodies of water that have an abundance of organic matter- so much so that the water is often brown. These bodies of water are often near bogs. Lakes can gain these types of nutrients through things such as runoff that bring soil nutrients into the water;

If I said green, grimy and Adelaide, your mind would instantly race to the contaminated River Torrens. The River Torrens makes up a 85km stretch of the Murray-Darling Basin and is vital to the water security of Australia. But, yet it used to flow on a seasonal basis through and would have been used for leisure activities, such as swimming. If you looked at the River Torrens now you could never tell that’s what it was used for, and instead, you can see the unsightly weir restricting water flow and the murky brown-green water plagued with environmental issues.

Catchments are depended on by the average household person, but even more valuable to the farmers that are supplying the food to our nation. Therefore, action must be taken to ensure that the catchments in our areas are healthy and will be able to be depended on for years to come. The panel at Healthy Water Ways program has developed a study to guarantee the management and sustainability of The Pioneer River catchment, by sending a team out to analyze the health of the water ways and decide on a proposal that best suits the area to ensure future healthiness of the basin.

Many new developments are being built by freshwater sources such as lakes and rivers and with this construction, riparian areas are being destroyed. Both of these actions negatively impact the amount of dissolved oxygen at the source. Industries such as construction and logging may send large amounts of organic matter into streams (Zaimes 2007). This organic matter would then be decomposed by microorganisms, which use up oxygen in this process. This process creates a eutrophic system where oxygen levels are depleted. Additionally, destruction of Riparian areas would decrease the tree cover and increase the water temperature. The significance of this temperature increase is that the water would be able to hold less dissolved oxygen. Many aquatic

As most would know, water an essential substance on earth for our survival. We need clean water each day to function properly whether it’s for drinking, bathing, watering, swimming or washing, as well as for our waters to be safe for our environment and marine life. So what would happen if our waters were to be unusable or untouchable for our ecosystem, and for us humans, to be so contaminated with waste that it may be impossible to fix? With this fact in mind, there is still hundreds, if not thousands of waterways, around Australia that are still contaminated and infested with waste. One local area that is known for rubbish pollution that leads to their waters is Brighton Le Sands. They are known for a large ethnic population who have huge gatherings and picnics around the beaches. In comparison, another local area is

The process of eutrophication is responsible for around one-half of the damaged lake ecosystems and around 60% of the

Ralph Nader said, “Water is the most precious, limited natural resource we have in this country. But because water belongs to no one, except the people… special interests, including government polluters, use it as their private sewers.” ( Ralph Nader, 1971) Without natural resources life itself would be impossible. Beginning at the conception of life until death, natural resources are transformed for human use; including but not limited to feed, clothe, shelter, and energy. We depend upon them for every material necessity, comfort, convenience, and protection in our lives today. Without an abundant source of that precious resources prosperity is completely out of reach.

Eutrophication, the enrichment of aquatic environments with excess nutrients, is a naturally occurring phenomenon characterized by excessive plant and algae growth. Eutrophication initially increases productivity and limits light penetration, and subsequently results in reduced growth, depleted inorganic carbon, and anoxic “dead zones” (Chislock, Doster, Zitomer, & Wilson, 2013). Historically, primary productivity has been considered limited by an individual nutrient (Gooddy et al., 2016). Schindler (1974) established the highly influential paradigm that phosphorus (P) is generally considered limiting in freshwater environments. However, this has been subject to debate by evidence of freshwater nitrogen (N) limitation, N/P co-limitation, and the role of spatial and temporal variation (Xu, Paerl, Qin, Zhu, & Gao, 2010; Hundey, Moser, Longstaffe, Michelutti, & Hladyniuk, 2014) Cultural eutrophication, resulting from anthropogenic nutrient pollution, and has increased in both frequency and intensity over the past century due to intensification of agriculture, industry and sewage disposal (Schindler, 1974). The causes and consequences of eutrophication are important to study because of the resulting direct and indirect effects on ecosystems alongside societal impacts (Chrislock et al., 2013). Further, the importance of this research should be emphasized in the context of climate change, human population growth and the associated environmental consequences of the 21st century.

Fred Pearce’s When the Rivers Run Dry offers a look at his principles regarding water management and usage. He advocates the use of more efficient water use and conservation technologies, observing that widespread techniques such as drip-irrigation are inefficient and wasteful. Pearce is also against desalination- noting that it produces large amounts of toxic brine, is detrimental to the ecology of the ocean, and is the wrong approach to solving water shortage. Pearce argues against the misuse and mistreatment of

Natural eutrophication occurs when a body of water builds up nutrients over a long period of time, enabling it to sustain and support multiple living organisms. Algae then starts to form, damaging the ecosystem and decreasing the quality of the water. Cultural eutrophication; on the other hand, is caused purely by external human interference; such as, domestic and industrial waste being dumped into rivers of lakes and uprooting trees making the soil dry and loose, causing an excess of nutrients being run-off into drainage
