change in Some Areas Obviously, the 21st century has been growing prosperity around the world and the rapid advances in science and technology, yet some people are of the opinion that the change may not happen in all the fields. In this essay, I will examine some areas which have been improved significantly and other areas which have not been. It is true that some fields such as technology, medical care, which have been changed a lot during past hundreds of years. Specifically, modern technology, the main driving force of our societies, results in higher productivity (e.g. advanced manufactured equipment), greater ease (e.g. state-of-the-art household appliances), more enjoyable game devices (e.g. PSP, Vii). Also, before the jet airliners were came in in the 1960s. For example, air travel was beyond the reach of most people. Furthermore, our knowledge of the world around us, especially foreign countries, was sketchy before the TV brought us the vivid imagines of documentaries. Clearly, modern technology has brought liberation from the boring work and set us free to enjoy the more interesting work and leisure. Besides, health care system has been changed apparently so more and more people can be entitled to free health care, and many even have the choice of their own doctors. The examples I have given is just a few of the many that I illustrate the case that many fields have been significantly changed. However, even though some areas have been improved, there are still other aspects that we need to make progress. Take environment as an example, due to the overgrazing and deforestation, some rain forests have been destroyed. Some factories discharge a host of toxic sewages, which have polluted the water and have threatened the public health. Another field which needs to improve is crime, the increasing crimes rates, which seriously interrupts the law-biding and peace-loving citizens. Thus, the government should fulfill its responsibility to make progress of these areas. To conclude, although human being has made some significant progresses, the government should also try to solve some severe problems such as pollution and crime.
