Developments in medical technology and health care systems, among many other factors, are leading to people having longer life expectancy than before. As this trend continues, in the future, we can expect the number of old people will be much greater than that of young people. In several ways, society may benefit from a growing proportion of senior citizens. However, I believe the rest of the world population would have to shoulder much more responsibilities and the global economy would face a serious labor crisis.
On the positive side, an increase in the number of old people means a greater pool of volunteers for community and government projects. These people are usually more financially comfortable and therefore more willing to contribute free labor to ameliorating their communities. For example, we often see old people in developed countries engage in charity work to provide shelter and food for the homeless in their neighborhoods. Such an act also instils a great sense of responsibility and altruism into the young generation. This is, in fact, globally recognized to be advantageous in a world where selfishness hinders one from taking action for the sake of others.
Nevertheless, aging populations will place the whole world under many pressures. Both governments and businesses will have to pay for increased retirement pensions and health care costs, which means tax-payers will have to bear a greater financial burden and the young workforce will have to work harder and care for the elderly at the same time. Furthermore, lack of young labor workforce would cause stagnation for the growth of individual businesses and the global economy as a whole because little innovation may take place in this circumstance. As a matter of fact, many first world countries whose proportion of senior citizens is higher than that of young people, such as Japan, are already experiencing these undesirable impacts.
In conclusion, an aging population is beneficial in certain ways. However, the benefits society may reap from an aging population cannot match the damage it inﬂicts. It is important that the world governments should not underestimate the complexity of this problem and take immediate action to reduce its future inﬂuences.
Years ago, humans sent spacecraft to explore the universe and satellites into orbit around our planet, and life on Earth has become better and better since then. Such technology facilitates global communication, predicts weather conditions and, most importantly, brings a whole new view of the potential of our technology and engineering. With this solid foundation, sending tourists into space is within our grasp, and many believe a new tourism industry could be developed in the years to come. Our climate will be affected, but I think it is an acceptable price to bring wealth and inspiration for future generations.
Space tourism could have major consequences for the earth’s climate. The emissions from rockets are enough to increase the temperature in areas around the launch site, and some scientists have discovered that this also causes temperatures at the north and south poles to increase, leading to global warming and rising sea levels.
Space tourism however, could easily become a multibillion-dollar industry that will bring great wealth to any economy that is involved. In the past, only selected astronauts were able to fly into space, but recently other people, particularly wealthy business figures, have become curious and aspire to have such an experience. Once orbital flights are arranged on a regular basis and made available for people, a great deal of money will be paid to travel into space.
Furthermore, space tourism will inspire new generations of engineers, which comes with a promise of new technological innovations. Travelling into space was once an unreal concept until Neil Armstrong set foot on the surface of the moon. It motivated millions of young engineers and scientists to reach a new height in space technology, such as satellites and orbital space stations around the earth. If space tourism were developed in the future, more and more technological breakthroughs would be expected to come into being. In conclusion, I think the benefits from space tourism are much more significant than the harmful impact it may have on our climate.
Travelling has been greatly facilitated by a number of technological advances in recent years, and ultimately, cars will be operated completely by computers in years to come. In my view, this can have both positive and negative consequences on society.
One of the main disadvantages of autonomous cars is that it will have an undesirable influence on employment rates of commercial drivers. There is little doubt that these people will be forced out of work when autonomous cars become the favored preference. This also leads to a more pressing concern about the associated consequences when unemployment rates proliferate, one of which is the increasing social burden placed upon the government. Considering the unprecedentedly fast development of car technology in recent years, such a scenario is likely to occur in the foreseeable future.
However, we should consider these disadvantages as inevitable factors that accompany a handful of more significant benefits. For one, autonomous vehicles can accurately navigate their way with less chance of making errors in judgment like human drivers do, hence, increasing the safety of passengers. It is true that the majority of traffic accidents come from situations where speed or alcohol is involved, which would not be the case if cars are operated by computers. Furthermore, such technology will inspire a new generation of mechanics and engineers, in turn, leading to more inventions that will make human life easier and more comfortable.
In conclusion, the predicted appearance of driverless cars will severely impact employment in the transportation industry and result in large social burdens upon the government. Nevertheless, I do think that those negative consequences are the prices we can accept in order to enhance road safety and nurture a new era or engineering.
Some people believe that despite the widespread popularity of the online media, traditional newspaper will still hold the most vital position among news readers. In my opinion, this idea is rather absurd as the Internet has become increasingly dominant due to the benefits it offers.
The first thing that attracts people to reading news on the online sources is their easy access. With the presence of the Internet around almost every corner of the world, people with a portable device such as a mobile phone can access huge storage of news. In fact, latest events, for example IS Terrorist attacks, would be updated immediately on CNN or New York Times. By contrast, with prolonging procedures including editing and printing, traditional newspaper might not be able to compete with the Internet in terms of the updating speed.
Another benefit with which the Internet can, from my point of view, take over the position of printed newspaper is the new experience it brings to readers. One limitation of newspaper is that it cannot convey visual messages to the people who read news on a regular basis. Meanwhile, non-stop progress of the technology industry has unfolded the possibility to upload videos and voice records on various online websites. For instance, soccer fans these days can re-watch their favorite matches anytime they want with only a laptop connected to the Internet, which a mere paper cannot do.
In conclusion, I disagree that printed newspaper would continue to be the most crucial source of information because more and more people will be drawn to use the Internet.
