Scientists and the news media are presenting ever more evidence of climate change.


Scientists and the news media are presenting ever more evidence of climate change. Governments cannot be expected to solve this problem. It is the responsibility of individuals to change their lifestyle to prevent further damage.

What are your views?

Answer:
Recently scientists worried about climate change have urged governments to introduce measures to reduce the greenhouse gas emissions that are seen as its main cause. Simoultaneouslty, politicians and environmentalists have urged individuals to make changes to their lifestyle. I shall argue that governments and individuals should take join responsibility for this problem.

Firstly, industry accounts for a large proportion of the greenhouse gas emissions, and this can only be controlled by government action. Measures could be taken to discourage pollution, such as limiting or taxing the use of fossil fuels. Alternatively, subsidies could be offered to industries to clean up their production processes. If these ideas were adopted, I believe that businesses would regard pollution as a financial issue.

Secondly, only discussion between governments can ensure that solutions are successful. The Kyoto agreement, for example, tried to reach global agreement on how to address the problem. Without such co-operating, it seems to me that efforts to reduce fuel consumption are unlikely to be effective.

However, national and international policies will only secceed if individuals also change their lifestyle. For example, people could think more carefully about how they use energy in their homes. By using less electricity, installing energy-efficient light bulbs and electrical appliances, or investing in solar panels, individuals can make a real difference.

In addition, I think individual attitudes to transport need to change. Instead of making short tips by car, people could choose to walk, cycle, or take a bus. Since cars are a major source of the problem, changing our behaviour in this area would have a major impact.

In conclusion, I would maintain that only a combination of international agreement, national policies, and changes in individual behaviour will succeed in preventing further damage to the environment.

We are becoming increasingly dependent on computers


We are becoming increasingly dependent on computers. They are used in businesses, hospitals, crime detection and even to fly planes.
What things will they be used for in the future? Is this dependence on computers a good thing or should we he more auspicious of their benefits?

Ans:
Computers are a relatively new invention. The first computers were built fifty years ago and it is only in the last thirty or so years that their influence has affected our everyday life. Personal computers were introduced as recently as the early eighties. In this short time they have made a tremendous impact on our lives. We are now so dependent on computers that it is hard to imagine what things would be like today without them. You have only got to go into a bank when their main computer is broken to appreciate the chaos that would occur if computers were suddenly removed world-wide.

In the future computers will be used to create bigger and even more sophisticated computers. The prospects for this are quite alarming. They will be so complex that no individual could hope to understand how they work. They will bring a lot of benefits but they will also increase the potential for unimaginable chaos. They will, for example, be able to fly planes and they will be able to co ordinate the movements of several planes in the vicinity of an airport. Providing all the computers are working correctly nothing can go wrong. If one small program fails disaster.

There is a certain inevitability that technology will progress and become increasingly complex. We should, however, ensure that we are still in a position where we are able to control technology. It will be all too easy to suddenly discover that technology is controlling us. By then it might be too late I believe that it is very important to be suspicious of the benefits that computers will bring and to make sure that we never become totally dependent on a completely technological world.
