SCIENCE AND TECHNOLOGY
‘This is the way the world ends. Not with a bang but a whimper.’
(T.S. Eliot)
И During this century the quantity of greenhouse gases will probably double and the average global temperature will rise by at least 2*C. That’s a bigger increase than any in the last 1.5 million years. This could completely alter the dilate in many regions and lead to disasters such as world food shortages, mass migration, wars for water and other resources.
Probability: High
3 It hasn’t happened yet, but one day it is almost certain that a terrorist group will get the necessary materials and technology to use weapons of mass destruction. A nuclear, chemical or biological terrorist attack will almost certainly happen in the next thirty years.
Probability: Very high
Some say the human race will go out with a bang; others predict a long slow death; while the optimists think we will live forever. What are the dangers we face and how probable is it that they will occur in the next seventy years?
In the last century we have had four major flu epidemics as well as HIV and SARS. There will certainly be another one in the near future. A virus probably wontaskt wipe out the whole human race. However, in 1918 influenza killed twenty million. A similar epidemic could be even worse today.
Probability: Very high
Over a long period, the risk of dying as a result of a meteor hitting the Earth is about the same as the risk of dying in a plane crash. A huge meteor hits the Earth about once every million years. It will happen again, and when it happens, an enormous cloud of dust will rise into the atmosphere. This will block out sunlight and kill plants. However, the most adaptable species (cockroaches and humans, for example) will probably survive.
Probability: Medium
0 By 2050 robots will probably be able to think like humans. They will look after us at home like mechanical servants. But they will also carry out more complex tasks. For example, they will be able to work as doctors or teachers. Some people think that the fantasies of science fiction films will come true. Humans wontaskt become extinct, but we will join together with advanced robots and make a new species that will live forever.
Probability: High
0 Approximately every 50,000 years a super volcano erupts.
The consequences are terrible and can last for years. It covers the land with ash, and a huge cloud of sulphuric acid circles the Earth. Daytime is like a moonlit night. Ice forms in the tropics.
A super volcano is twelve times more likely than a large meteorite impact.
Probability: Very high
So there you are. The future is full of dangers and the world will end one day. However, I really don’t feel too worried. It may be irrational, but I actually feel optimistic. I think ittasks going to be very hard to kill off the human race. And I’m quite looking forward to having my robot servant.

9 Work in groups. Use the language from
Exercise 8 and the prompts below to discuss this statement.
I feel optimistic about the future. There is, of course, the risk that humanity will disappear in some disaster, but I believe that we will evolve into a more intelligent species.
• Say what you think the future will be like.
• Mention the dangers in the text. Say how probable you think (hey are.
A I believe the biggest danger we face is climate charge.
В I dontaskt agree. The c-climate will definitely charge, but we will probably Survive.
