¶ … water in your area? ("Your perspective on water differs whether you live near the Great Lakes, in the arid west, or by the coast."(McCarthy, 2009)
Outline a brief water conservation plan for your own daily use. How will these changes affect your personal life? What impact will it have on your local water supply?
There is plentiful water in my region (I live in the Great Lakes region). Nonetheless, a brief water conservation plan is the following:
To use water for just its needs and to ensure that tap water is not left running in between those needs.
To double used bathwater as water that can be used for washing the floor.
To, as much as possible, use rainwater for gardening
In order to supply water to humans certain technologies must be utilized.
Desalination is one of the methods that are used for promoting pure water supply. It literally means separating slat form water and thereby increasing the water supply that way, but it is a controversial solution since, although it works, it is also costly.
Australia's Sydney was recently torn over desalination plans. They planned to build a desalination plant that would extract a reasonable amount of seawater from his water, pump the rest back to sea, whilst the purified water would be pumped into houses, businesses and so forth.
One of the advantages of desalination is that it can act as backup if dam levels are low, or if there is a drought.
The disadvantage, however, is that construction of this plant is costly and can consume too much energy such as heat and electricity. It also consumes too much oxygen levels and results in an increase of the density of waste water. None of this is good for the environment.
Further detrimental for the environment is the fact that there will be an increase in production of greenhouse gas emissions.
These are the advantages and disadvantages of desalination, and it is for these reasons that Sydney was torn over the idea. (H20. Not worth one's salt.)
WEEK 2
global climate change.
Part I. Questions:
Do you agree with President Obama's proposed commitments during the Copenhagen Climate Conference?
Obama called the conference a 'meaningful agreement', but it seems as though Obama's trip to the Copenhagen Climate Conference was a farce. He proposed that the world regulate their temperature rises to no more than 2C and that the UN assist developing nations in economically helping poor countries fight global warming.
On the one hand, the UN talks were symbolically important showing the need for global change. On the other hand, the talks were unrealistic and even counterproductive since media focus (e.g. Groves, 2009 ) was turned on Greenpeace activists who were turned away and the event was contrived to block out protestors.
Rather than focus on the lack of a binding UN treaty, the administration would do better to focus on the real problem which is the concentration of greenhouse gases in Earth's atmosphere.
As reality, the world's two top greenhouse gas emitters -- China and the United States -- are reluctant to make drops in greenhouse emissions due to economic reasons rather than lack of concern for the climate. No UN treaty will change this. The best way to change this, in fact, is through developing cheap new energy technology rather than through a UN treaty.
Another more practical strategy would have been to promote existing low-carbon technologies, such as nuclear power and creating greater incentives for creating and globally disseminating new energy technologies. The UN could have massed to discuss more practical aspects such as cooperating in international research and development investment fund that would share intellectual property rights as well as creating policies that would guide and structure these endeavors. Domestic policies for limiting emissions that would differ from country to country would have been another reasonable issue.
In short, the climate conference -- and Obama's talks in it -- was symbolic, but practical and realistic measures are needed (U.S. News, 2009)
WEEK 3
Farmers, animal breeders, and scientists have been making genetic selections for desirable characteristics in farm plants and animals for centuries using traditional breeding methods. Genetic engineering has the potential to accomplish this in a fraction of the time. However, the production of genetically modified plants and farm animals using the new techniques in molecular biology is controversial. Furthermore, the development of genetic engineering technology opens possibility of cloning human body parts or even individuals.
What is your opinion on creating, growing, and consuming genetically modified plants (GMOs)?
Proponents of GMOs see these as the benefits:
-GM crops can be made resistant to viruses, fungi and bacterial growth.
-GM crops can be engineered to grow faster.
-GM crops can be engineered to be naturally pest-resistant, undermining the need for pesticide chemicals.
-GM crops can be engineered...
Given water scarcity, the high costs of desalinisation and other unconventional methods of supplying water, and the pollution of surface and ground waters, Israel sought other natural supplies of water from the Litani" (Dolatyar, 2002). The Israeli then invaded Lebanon, but were met with extreme resistance. 1990 - Present - Period of return to bargaining tactic The fall of the Soviet Union, the Gulf War (1990-1991) and the interference of the
Water Privatization How Privatization of Water is Bad for the World Water is a scarce resource, a fact that is becoming more evident as time goes on and pollution becomes more evident. There are many instances where privatization has been beneficial; bureaucratic red tape often makes policy making a headache for consumers, and some eagerly advocate for privatization of certain resources. Privatization often has advantages, but in many instances it also realizes
Water Awareness and Education for Sustainable Watershed Management Today, the human society continuously deals with the issue of limited resources, as compared to an extensively growing amount of needs. Among these limited resources, water is vital, not only because mankind cannot survive without it, but also because it is essential to producing so many other secondary items, including food and clothing. At the same time, water and watersheds are an essential
The case of the World Commission on Dams is a good example of how this tendency to centralize water resource management can be mitigated, if not completely eliminated. The political reality of the world is that government represents more than just laws and policies, just as management and governance has to be about more than just enacting laws and edicts, but should reflect the values of the community and the
Water Supply by Water Health International to Honduras This is the section that gives a brief summary of the entire project or paper, citing the particular areas of emphasis that will be expounded upon in the body of the paper. It enables one to highlight the used methods and the hypothesis being tested (Literacy Education Online, 1998). In this particular case, the abstract will briefly indicate the prompt to the research,
While on one hand, the Nile gets the highest discharge from rainfall on the highlands of Ethiopia and upland plateau of East Africa, located well outside the Middle East region; on the other hand, discharge points of the other two rivers, Euphrates and Tigris, are positioned well within the Middle East region, prevailing mostly in Turkey, Syria along with Iraq. In other areas, recurrent river systems are restricted to
