nuclear power is the best energy



ĐỀ 08-09-2013
Nuclear power is considered to be roughly the best energy compared with other energy sources to meet growing energy demand in the world. Do you agree or disagree?

Pros
- mass produced
- cleaner and reduce the amount of CO2 released
- cheaper
- save the exploitation of other natural resources
Cons
- expensive in the construction
- require high expertise
- risky in case of accidents

Nuclear power is often used in developed countries. Some people believe that compared with other sources, it is the best one in terms of cost-effectiveness while others claim that it is extremely dangerous in case of nuclear leakage or explosion. I partly agree with the statement for the following reasons.

It is, first, argued that nuclear energy is mass produced. Solar or wind energy which is derived from natural resources proves limited while nuclear energy is created in great quantities by applying high technology. Nevertheless, so as to build nuclear power plants demands a great amount of time and effort. It is estimated to take more than a decade to finish a plant whereas governments, at the same time, put all effort in training experts to run it. High technology and expertise are required in the completion of nuclear power plants, in other words.

Second, the belief is that this source reduces the amount of carbon dioxide released into the atmosphere in comparison with its counter-part and saves the exploitation of other natural resources. According to scientific statistics, the rate of carbon dioxide discharged from burning waste and hydro power is ten times as high as that from nuclear energy. Besides, once nuclear power dominates, there is no need for governments to try to make use of other limited natural resources like wind, solar or water. Yet, in case of unwanted accidents, risks caused by nuclear explosion are far more hazardous. Chernobyl in Russia is a telling example. Thousands of people suffered respiration problems while the next generation were faced with birth defects. Environmentally speaking, the entire area near the explosion was submerged into radioactivity environment, leaving people unable to live.

In brief, nuclear energy has its both pros and cons. Depending on economic condition and long-term plans of each nation, government can use it or apply others to meet the demand of their citizens.

People are not paying attention to environmental protection. Causes and solutions ??



ĐỀ 16/4/2011
People are not paying attention to environmental protection. Give causes and solutions.

Causes :
-         Governments : lack of effort and law enforcement
-         Objective reasons : economic imbalance between nations
Solutions:
-         Governments : prohibition of natural exploitation, discouragement of private transportation, establishment of international treaties.
-         Citizens: awareness of environment protection through educational programs
-         Children : inculcating with consequences of environmental damage

Environment is calling our name worldwide, especially with the frequent occurance of natural disasters from tsunami to earthquakes. That is the acknowledged threat to the survival of humankind, but the truth remains that people seem to be busy with something else, rather than the mission of salvaging the world before it is too late. Reasons for peole’s blatant ignorance of this fact are various, subjectively and objectively.

Governments are partly to be condemned for their lack of serious effort and radical law enforcement on environment protection. The fact is that people around the globe are still releasing a huge amount of waste, without being heavily penaltized or get away with this, perhaps by simply lobbying government or bribing some key figures in the authorities. Also, despite the fact that authorities are urging people into using environment friendly products and campaigns to keep the environment clean, ironically, they are, simultaneously, allowing businessmen to produce as many cars as possible and advertisers to spur consumerism among people. This is undeniably the catalyst for the booming of air pollution and early exhaustion of natural resources.

Objectively, economic imbalance between nations is another culprit of people’s little attention to save the environment. While some nations pass their economic heights, being willing to voice their protests against any action dirtying the environment, others are too hectic with the prodding call of poverty and illiteracy of citizens and find themselves at variance with priorities of developed world. In this case, any attempt to slow down the development of the latter proves paradoxical, and for that reason, our environment stays fully exploited. The painful truth is that the inherent basic instinct of people, after all, is to feed themselves as much as possible, before thinking of preserving their environment.

Solutions to this head-aching issue are suggested. Drastic measures implemented by governments to minimize pollution are the prohibition of natural exploitation above the limit, discouragement of private means of transportation, and establishment of international treaties, for instance, Kyoto. Nevertheless, this means no worth if each citizens, himself of herself, pays no heed. Long-term remedies, educational programs to raise people’s awareness of environment protection are strongly recommended. It would be such an effective method to inculcate in our little children the immediate consequences of environmental damage, by introducing the environment protection as the mandatory subject at school and frequently showing videos of environment hazards on TV everywhere. I strongly believe that once these threats caused environment degradations are deeply embeded in our minds, especially, children’s, our environment will soon be away from jeopardy and our world will be green again.

Is it too late to save environment ??



ĐỀ 10/11/2011
Human activity has had very negative effect on plant and animal species. Some people think that it is too late to do anything to problem, while others believe that effective action can still be taken to improve the situation. Discuss.

Endangered species :
-         Tsunami, green-house effects, global warming and other phenomenon result in the vast disappearance of plants.
-         Animals are, second, thought to be the most to suffer for their mass extinction.
Human activities
-         High technology brings better alternatives, and policies are taken to ask each individual to take part in the campaigns to plant trees and keep waste in check.
-    Scientists and environmentalists reproduce the gene of these animals and spurring the government to place researched animals on the list of danger.

Human has changed our world amazingly since the dawn of history. To some, such shifts human has brought are inevitable and promise the foundation for a civilized planet while pessimists who claim that their actions cause more pains than gains to the kingdom of plants and animals and it is far too late to rescue anything. I strongly believe with a better awareness, people are still able to save our world for the following reasons.

First, people casting doubts of the sustenance of the plants cite abundance of evidence to prove their point. Never do we experience such a non-stop attack of natural disasters caused by so-called over-heating economics of several nations. Tsunami, green-house effects, global warming and other phenomenons become acknowledged threats and trigger more critical erosion, which results in the vast disappearance of plants. Despite human’s effort to call for people’s higher awareness of environment protection, such menaces are here to stay. According to the world’s environmental statistics, three fourth of the globe’s woodland over a century has vanished without a trace. Nevertheless, optimists hold the firm belief that no matter how gloomy the picture of environment may sound, actions of human have been, in time, taken to curb this. Let’s take example the new evidence collected from scientific sources. Until now, high technology offers better alternatives to produce synthetic materials instead of exploiting natural resources while policies, especially in developed nations, such as Singapore and Australia are immediately taken to ask each individual to enthusiastically take part in the campaigns to plant trees and keep waste in check. Creatively, for the time being, houses architecturally surrounded by plants attached to the walls become a trend in Japan, which indicates a closer lianson between human and plants. In other words, in accompany with increasing threats are also escalating actions from human to save our plants.

Animals are, second, thought to be the most to suffer for their mass extinction. Figures have stated that the number of endangered species is higher than ever; in a day in the world somewhere, there are about at least two or three estimated put on this list of dying, but it seems that humans are still so busy with other urges instead of taking deeds to protect their survival. The truth is that the rare genes in these animals, once gone, are unable to be created. A typical example is the case of our great friend, dinosaur which ever contributed significantly to the ecological balance. Even worse, for the sake of profit,  mercenary people are harnessing the skin of animals as cosmetics whereas some are using animals as the object of their research. Yet, is it a total refutation to exclude all human’s genuine effort to save animals? With the scientists and environmentalists working at a long stretch to come up with cutting edge innovations to reproduce the gene of these animals on the list of danger, optimists confirm that several species have actually escaped from the label of extinction. Dolly Sheep is a telling instance of an animal in which scientists have successfully recreated its destiny through genetic studies. Besides, the appearance of ever-increasing zoos and aquariums around the world is self-evident to show that the animal shelters are taken care more than ever. America, according to the annual survey, has poured a dramatic amount of money into the reconstruction of animal kingdoms, such as sea-worlds, so as to raise people’s awareness of species in human’s life and cement the bond between animals and human through creative shows. At a more macro levels, the cross-border legal terms and conditions on the animals’ and plants’ conservation, for example, no testing on animals for cosmetic products, are passed and conferences on the solutions to remedy these problems are seen.

In the final analysis, both the bright and dark sides of the picture are noticed. The most important, I believe, is not about the lateness or earliness, but let’s prioritize the survival of animals and plants over ours to have a better world at any time.
