An Essay about Technological Change

There have been dramatic technological changes over the past 100 years, such as electricity, motorized transport, aircraft, space exploration, medical advances, computer technology.
Important changes have taken place in the coming century, esp. In the following areas: information technology; biotechnology; alternative energy sources.

The first area of significant change is likely to be computer technology it has developed rapidly in the past few decades. Bill Clinton became US pres. In Jan 1993 - only 50 WebPages existed on the Internet. This is still likely to be a major area of change in the coming decades. Computerized houses are already invented, where your fridge can be programmed to order fresh milk.

Another area of change is the biotechnology is likely to change our lives significantly. Genetically modified crops will grow in climates that were previously impossible. For example wheat in semiarid areas and tropical fruits in the far north will be grow. And will also have higher yields than in the past. Livestock will be modified to produce higher yields of milk and meat. Human beings will be modified to eliminate inherited diseases.

A major challenge facing the world at the end of the 20th century. Global warming resulting from man made pollution. It is likely that alternative energy sources will soon be exploited more seriously. Solar, wind and wave energy Nuclear energy will be also made. Perhaps we will abandon high speed vehicles and accept slower, more energy efficient ones to the benefit of our own existence because of the global warming problem these will help us preserve the world.

In summary, we can expect major changes in the areas of IT. Biotechnology and energy use, also the technology to be better in a future to the benefit of all the human being.
