deterioration
of the natural environment. Accompanied by technological development,
many problems, such as over-exploitation of natural resources, intense use of
artificial
fertilisers,
reliance on automobiles and deforestation, have arisen and intensified. Even worse, little progress has
been made toward addressing these problems, possibly because implementing environmentally friendly
policies will inevitably impede the development of energy-intensive industries. That is why the use of
petrol continues to climb, despite the fact that many countries pledge to curb petrol use and discover or
invent alternative resources.
Another problem is that many technologies have put people at great risks and highlighted the need for
innovation. For example, the spread of the Internet is directly responsible for people's sedentary lifestyle
and many health problems, such as obesity. The rise of the fast food industry, owing mainly to the
development in the food processing technology, is linked to diabetes, stroke and heart disease. Many
stress-related diseases are attributed to the increasingly fierce competition in society, a result of
technological development. Fears of job loss have become one of the most common sources of social
anxiety in these years, as computerisation has undermined the traditional position of labour by
eliminating jobs. All these problems demand quick solutions.
Some other problems are associated with technology as well, although the actual impacts remain
unforeseen. For example, the future of genetic engineering, a radical new technology intending to
introduce genetic changes to a species, either animals or plants, and to increase crop yield, is dim. To
date there is no compelling evidence to show that GE food has a good
track record
for human safety,
especially when it has been found related to thousands of poisoning cases.
Overall, whether technology is a blessing to people remains yet to be seen, so does what the 21st century
can bring to them. It seems to be a fact that whenever a new technology arises, there must be some
problems that follow. When people are impressed by the benefits brought by a new technology, it is
important to evaluate its negative impacts and take
precautions
in advance.
