Freshwater & resource Essay Example for Free

Freshwater resource Essay Freshwater is a valuable natural resource, but freshwater is only 3% of the total volume of water in the world. Two-thirds of this is found in glaciers and polar ice caps; thus leaves only 1% which can be readily acquired. Humans and other living organism on Earth need water to be able to survive. Freshwater is important in the transportation of nutrients in soil and is necessary for the propagation of plantations that support life for other organisms. Freshwater is a scarce resource; however it is easily contaminated by human activities. Human activities such as mining can contaminate rivers with heavy metals. It can also disrupt the ecological balance that requires the use of freshwater. Farmers who use excessive pesticide can contaminate freshwater supplies. Pesticides sip into the soil and flows to rivers when it rains. This human activities causes health problems, not only to humans but to other organisms as well. In some regions of the world, freshwater is not used efficiently. Irrigations and artificial dams disturb the water ecosystem. Irrigations and artificial dams direct the flow of freshwater to other paths which can harm organism who highly require freshwater. The ecological balance is destroyed which can affect several organisms that is part of the ecosystem. Excessive irrigation also induces desertification. Desertification is the decline of biological and economic activity of the soil. Desertification has been seen places around the world, such as China wherein farmers used irrigation inefficiently. Freshwater is renewable but it should be used in way that nothing is wasted. More and more people over the world are experiencing the lack of freshwater. Creating an effective water management is the only solution for this problem. References Richter, B. (2003). Ecologically sustainable water management: managing river flows for ecological integrity.

Leaders and Businessmen of the Victorian Era Essay examples -- Victori

Uneducated Gentlemen: The Leaders and Businessmen of the Victorian Era Changing Intentions of Public Education The public education system in Victorian England was originally intended for the education of the poorer working classes, and the training of clergy (Landow, par. 2). The children of the upper classes were often educated at home by private tutors, and therefore it was assumed the public schools would be a place for members of the lower classes. Despite the original intentions of public education, the schools eventually became a primary means of helping to elevate the status of the middle classes. In fact, rather than being primarily concerned with the imparting of knowledge, â€Å"the whole educational process was designed to mold the student into a young Christian Gentleman† (Everett, par. 2). The middle and upper classes wanted to keep children of the working classes from being educated, perhaps as a means of social control, and thus according to Eric Hobsbawm, in 1897 less than 7% of academic secondary school students were members of the working class (qtd. in Landow, pa...

Critical Thinking and Ethics Essay

In a discussion of ethics, critical thinking may not be the first term that comes to mind, unless opposing. However in some ways, critical thinking can the foundation, from which an ethical decision is made. This paper will explain the relationship between critical thinking and ethics, how the principles and rules of critical thinking are applicable to ethical reasoning, and if ethical decisions would be necessary if everyone followed the rules of logic. Is Critical Thinking Applicable to Ethical Reasoning? Ethical reasoning is based on the principles of what is considered right and wrong. Critical thinking on the other hand, warrants more of a thought process, causing one to analyze the situation from all aspects before reaching a conclusion. â€Å"By taking the path of a critical thinker, a person develops a mental process of evaluation which helps to determine their ethical standards† (Mnmelillo, 2010, Professional Growth, para. 1). Logic versus Ethical Reasoning The purpose of logic is to find that which is true. Logical thinking processes are often times used in ethics to answer important moral questions. However logic does not guarantee a morally correct outcome. For example, the legalization of marijuana is constantly under debate. Using the rules of logic, one would be able to see both the pros and cons of this argument. Although drug use is considered unethical by US government standards, even for medicinal use, the state of California, has legalized medicinal marijuana. In this particular case or should I say state, the rules of logic did not produce a morally correct result. Conclusion Ethical reasoning and critical thinking are derived from different  processes, although there are circumstances in which one is necessary to reach a decision regarding the other. As with critical thinking, there are no hard rules determining the use of ethics, considering what may be unethical in some cultures, for example, may prove to be ethical in another. Ultimately the use of ethics versus critical thinking or logic is determined by the situation at hand. Reference: Mnmelillo, N. (2010). What is the relationship between critical thinking and ethics?
