答案 On Nov.21st, 1999, this column carried an article asserting our world is too dependent on oil and that without oil the world would be ruined. It especially mentions transportation means. Here I have to say I cannot agree to this statement. It is true that oil is playing a very important role in our life, economically, politically and militarily. Many wars have happened in the Middle East because of oil, the US-Iraq War in early 90s is a good example. But that does not necessarily mean that without oil our world would meet its doom. There are many energy sources that we are using even today. Take electricity for example. While we are using some electricity produced by oil, most of it is produced by coal and water. We also know that many countries, especially in developed countries, a high percentage of electricity is from nuclear power stations. Well, let us also take transportation means for example to see if without oil we would be able to go nowhere. First let us look at trains. In some places, diesel is used as fuel. But diesel is frequently replaced by electricity. Then let us look at cars and buses. In Beijing, buses have started using LNG (liquefied natural gas) -- not LPG (liquefied petroleum gas), by the way. One may ask how about planes? Yes, at present, planes mainly fly by oil. But planes are not everything. What is more, so far as I know, scientists are testing the substitutions of oil because the resource of petroleum underground cannot last forever. In conclusion, oil is important, but it is not indispensable, especially in the future.
