Water contamination is a serious form of pollution, and one that can be challenging to rectify. There seem to be two main causes involved, and a variety of damaging effects on people and the biosphere, which we will discuss here.

Probably the main factor is the issue of emissions from cars, factories and other human activities. These emissions contain damaging pollutant particles which can contaminate rainwater run-off and thus enter the water cycle, by transferring through the water table into aquifers, streams and rivers. Filtration and processing are not really viable options for such large volumes of water, and so the water table remains tainted with these elements over long periods, as we see in Eastern Europe today. In situations where soil erosion and logging have already damaged the local environment, the accumulation can be very serious. The other major cause is accidental or deliberate dumping of waste products in places outside of controlled landfills or waste processing centres. Even small amounts of abandoned waste can enter water supplies through the ground, often undetected.

The effects on animal life can be severe, especially for species which are already endangered by such threats as poaching, habitat loss and food chain disruption. Contaminated water can lead to dwindling numbers or even potential extinction, as may indeed happen to the Asian tiger populations. The impact on human society can also be distressing, including the poisoning of drinking water, famine or drought due to lack of safe irrigation, and long-term loss of land as we see, for example, after the Bhopal poisoning catastrophe in India. Such effects tend to have an especially grave impact on the very poorest in society, with the least resources to counter the environmental effects.

Overall, we see that emissions and dumping are the main origins of the problem, and that the effects on both humans and animals are exacerbated by the existing environmental, criminal or social problems.

Cycling is more environmentally friendly than other forms of transport. Why is it not popular in many places? And how to increase its popularity?

Although riding a bicycle is clearly a better way to protect the environment than using other types of vehicles, not many people around the world prefer this means of transport. There are several causes of this unpopularity, and some solutions could be proposed to promote the usage of bicycles.

To begin with, there are several reasons why few people use bicycles to travel on a regular basis. Firstly, since modern life is getting much busier than in the past, individuals nowadays want to spend as little time on transport as possible. Therefore, they prefer to use other types of vehicles such as motorbikes or cars which would take less time. Secondly, cycling is more physically demanding than riding a motorbike or driving a car. This tends to discourage people from choosing this method, especially on a hot and sunny day or when they have to travel a long distance.

Several actions can be taken to increase the popularity of bicycles. The first solution would be to make it more costly to own a motorbike or a car. This can be done by increasing the price of petrol or raising tax on these vehicles. As a result, more people would choose bicycles as their primary means of transport. Additionally, more lanes should be built to serve only cyclists, which would make it much faster to travel with bicycles. The final solution is to launch campaigns to raise citizens' awareness of the harmful effects of motorbikes and cars on the environment, and this could encourage people to cycle more often.

In conclusion, there are some reasons why bicycles are becoming less common in today's world, and solutions should be produced early to romote this environmentally friendly means of transport.

The consumption of the world's resources (oil, and water etc.) is increasing at a dangerous rate. What are causes and solutions?

The accelerating rate of natural resources consumption has been a major topic of concern in recent  years.  As  some  factors  are  likely  to  trigger  this  alarming  trend,  a  number  of  drastic measures can be employed to slow down the pace.

Perhaps it is the key role of natural resources in boosting economic growth and the heavy reliance on natural resources that accompany each other to create this dire situation. Today, precious commodities from nature such as gas, oil and coal still remain crucial to the operation of a country as transport and industries would grind to a halt without the energy and fuel generated from these resources.  In  emerging  economies  which  are  striving  to  rise,  the  demands  for  resources  are certainly on the increase. The dependence on natural resources is also to blame as it is easier to exploit them from nature than developing and converting to sustainable alternatives such as wind and solar energy, which requires many years and great determination to produce  changes on a large scale.

In  order  to  alleviate  the  existing  problem,  there  are  some  feasible  solutions.  One  step  to  be mentioned is that the authority should impose higher taxes on the use of natural resources to deter further consumption. On the other hand, renewable energy sources such as solar and wind power  can  be  developed  to  substitute  fossil  fuels  in  transport  and  manufacture.  Lastly, governmental  campaigns  need  to  be  launched  to  make  individuals  acknowledge  the  risks  of overusing natural resources through the mass media.

In  conclusion,  the  overuse  of  the  world’s  resources  may  result  in  severe  consequences, threatening the environment and many people’s life, and strong measures must be implemented to tackle this situation.

The world natural resources are consumed at an ever-increased rate. What are the dangers of this situation? What should we do?

đăng 18:03, 20 thg 3, 2017 bởi Nam Đỗ Hoàng   [ đã cập nhật 18:03, 20 thg 3, 2017 ]

The overconsumption of natural resources has evolved has a major topic of concern in recent years. This alarming trend poses a number of serious threats to the world, and must be addressed with a number of definite actions.

The increasingly high level of natural resources exploitation can be hazardous in many ways. The most obvious threat is that once the resources come to the verge of depletion, humans would have to face the scarcity of fuels and materials. When oil becomes scarce and more expensive, transport and heating would become less accessible and affordable to most people. The shortage of resources also leads to stagnation in other industries, for example, there would not be enough wood for furniture production and not enough seafood for food processing. This would threaten the business of thousands of companies, as well as the employment of millions of workers in these fields.

Some measures can be taken to mitigate the problem of over-consuming natural resources. The most practical measure is to lower the demand for energy in every household. This can be done by mass-producing energy-efficient household appliances and selling them at a low price. Energy demand may also be cut by making saving energy the focus in propaganda campaigns in various media channels. Another sustainable solution is to promote environmentally-friendly technology. For instance, solar cells are now sold in a small quantity and at a relative high price; they should be made readier and cheaper for the public. Finally, the conservation and recovery of natural resources, including seafood and forests, must be regulated by law.

To conclude, the overexploitation of the world’s resources may result in severe consequences, threatening many industries and people’s life. Strong measures, such as reducing energy use and resource conservation and recovery laws, must be implemented to tackle this situation.

Development in technology has brought various environmental problems. Some believe that people need to live simpler lives to solve environmental problems. Others, however, believe technology is the way to solve these problems. Discuss both views and give your own opinion.

The improvements in technology currently bring about harmful effects on the environment. While some people believe having simpler lives is the only solution, I would argue that technological advances can help to tackle these environmental problems.

On  the  one  hand,  it  is  believed  that  individuals  need  to  live  simple  lives  and  rely  less  on technology. The first suggestion is that people should walk or cycle rather than drive cars. This is because the current number of cars  being manufactured and used is increasing, which causes high levels of exhaust fumes and makes air pollution become serious. Additionally, people should try to reduce their consumption of electricity so that the exploitation of natural resources such as fossil fuels or nuclear power can be minimised. An example of this idea is the annual event called Earth Hour where everyone is asked to turn their lights off for sixty minutes.

On  the  other  hand,  I  believe  the  developments  of  technology  can  greatly  contribute  to environmental protection. Firstly, because of those improvements, people are able to come up with  ways  to  recycle  materials  such  as  paper  or  glass,  which  reduces  the  problem  of  waste disposal. Secondly, technology can also help to create electricity using renewable resources. For example, many countries in the world have built plants that utilise solar energy to generate power. As  a  result,  it  is  not  necessary  to  rely  on  non-renewable  resources,  and  people  can  create electricity without significantly damaging the environment.

In conclusion, while some people think that they should live simpler lives to prevent environmental issues, I would argue that these problems can be dealt with by technological improvements.

It is now possible for scientists and tourists to travel to remote natural environment, such as the South Pole. Do the advantages of this development outweigh the disadvantages?

đăng 01:34, 20 thg 3, 2017 bởi Nam Đỗ Hoàng   [ đã cập nhật 02:08, 20 thg 3, 2017 ]

It is true that humans can now set foot in wild regions far away from civilisation. While I accept that this development can have certain benefits for the human race, I believe that it is likely to
have a harmful impact on nature.

On the one hand, undertaking expeditions to the wilderness can be valuable in terms of both science and recreation. There are a considerable number of undiscovered secrets that can be tremendously useful for researchers to conduct their studies. For instance, environmental scientists can analyse the data about the thickness of ice layers over millions of years in both hemispheres to predict the possible changes in global temperatures. Such findings are crucial for the governments to develop appropriate plans to alleviate global warming. Furthermore, the untouched beauty of these areas is usually appealing to travellers, providing people with an attractive option of holiday destination or excursion. 

However, I would argue that these positive aspects are outweighed by the drawbacks. When people are given full and easy access to the distant and unpopulated areas, there are likely to be more moving there to reside or start their business. It has been shown that substantial damage has been done to nature such as massive deforestation or water contamination due to humans’ lack of environmental awareness. If there is inadequate protection of the environment from this type of action, wild regions in the world will no longer exist, unspeakably affecting not only the overall ecology but also the lives of other people.

In conclusion, it seems to me that the potential dangers of travelling to wild environments are
more significant than the possible benefits for the mentioned reasons.
