Water scarcity Nowadays, we are facing the threat of water scarcity. This essay will discuss the reasons behind that, and think about how to solve it. With the growth of population, the demand for water resources is tremendously increasing. Whatever agricultural, industrial, or domestic use of water has been rising at a dramatic rate. At the same time, some rivers, lakes, and seas are suffering pollution from frequent human activities. Also, improper use of water can be seen everywhere. Huge amounts of water are wasted by factories, farms, and families every day. Therefore, we should take some measures to solve the problem. The government should control the population growth rate for sustainable development. Meanwhile, those factories or individuals who cause a lot of water pollutants should be punished at heavily fined. As a citizen, we should try to more cherish water by doing things as simple as reusing the dirty water to flush the toilet, turning off the tap when we are brushing our teeth, etc.. And educational department should emphasis the shortage of freshwater, and make students care more about the use of water and reduce waste of water. In addition, scientific research on desalination technology should be encouraged and funded more. For example, scientists can focus on translating seawater to freshwater. In conclusion, there is a range of reasons for the lack of fresh water, such as the growth of population, water pollution, and the arbitrary use of freshwater resources. We should take some steps to ease the issue, like control the population growth rate, promote the academic research on alternative sources of freshwater, and most importantly, do some simple things to reduce the waste of water by ourselves.

The influence of the news media The news media, such as newspapers, news magazines, television reports, and news media networks, form a necessary part of our life. From my perspective, I think the popularity of news media have both positive and negative effects. First of all, it is no doubt that news media can spread out important social events to citizens. It can play a significant role in transferring information and knowledge to the public. For example, people can learn the common sense of how to distinguish financial fraud from existing criminal cases. At the same time, people are curious about what happened in the surrounding. By acquiring different news, people can make better-informed decisions and improve their competitive advantages. For instance, people can choose their idea company by the prediction of the future of a corporation according to its recent behavior. However, on the other hand, the news might be controlled easily by some power person or consortium. Under the tempt and pressure, some media might choose to reported biased information and produce fake news. In this situation, citizens are very likely to be influenced by these biased views. And some false news can seriously affect the reputation of celebrities since most of us will be attracted to exaggerate fact. To conclude, the news report can be beneficial to the public by the functions of spread knowledge and satisfy curiosity. Meanwhile, we should be careful of some false reports, and these press should be punished by the law. News media should undertake their social responsibilities because they are so influential to our lives.

The impact of cheap airfares It is more and more common that air-plane tickets are sales at low prices. Some people argue that it has a lot of disadvantages. However, from my perspective, I think it is, overall, a positive development. First of all, it can improve the affordability of flights tickets. In the past, a vast majority of people unable to travel to many other countries because of the expensive flights. The low-cost flights can extremely give more people access to air travel and help them to save money. Secondly, low-budget flights can boost the growth of tourism. Compared to travel by car or by train, air trip can give tourists more freedom to wander their destinations and consume in the local, which due to the time-saving and cost-saving. This means that they can more enjoy the attractions that they wish to visit. Thirdly, traveling by flight also makes guests feel more comfortable than by other vehicles. There might be someones who argue that economy flight can not provide a sufficient cozy environment. In fact, the inexpensive flights provide the same seats as the seats located in regular flight in most case. Fourthly, some people might complain that cheap flight will consume more fuels and damages to the environment. Nevertheless, traveling by air are far more eco-friendly than by other transportation because passenger planes can carry more people than cars and coaches do. By summarize, cheap air trip can offer us affordable and comfortable experience, which can also dramatically promote the booming of tourism. At the same time, it also can be beneficial to the sustainable development of the Earth.

Should companies move to the suburbs? Nowadays it is tension to build up business in urban area due to the issues of traffic and housing. Therefore some people argue that it might better to move them to the rural area. In my opinion, relocating to the rural area has both advantages and disadvantages. First of all, it is evident that the urban area has more business opportunities. That is because the people who live in an urban area usually have more funds and demands. For example, the central city cinemas can appeal to more customer due to the high visitors flow rates. Besides, fewer people are willing to move to a rural area, which causes a lack of labor resources. It is common that urban area has more advance level of medicine and education, which leads most people to prefer to live and work in an urban area. On the other hand, if the business set up in an urban area that will bring up too many burdens to an enterprise. For example, the boss and investors need to afford the expensive place renting fees. At the same time, they also need to set higher wages than a rural area to compensate for the higher living costs of employees. Meanwhile, they are facing the problems of traffic jam in the urban area. Relatively, it is more comfortable to commute in the suburbs. The high housing fees also trouble for citizens, and it might ease the problem by moving to a rural area. In a nutshell, I think it should be considered carefully to choose a place to set up a business for the benefit of both enterprises and employees.
