being
Technological development brings drawbacks

2. Introduction
 Human survival, compared to 20 million years ago and 10 million
years ago, will not change much. And compared to two thousand
years ago, three thousand years ago, there will not be much change.
However, most people have changed, even now, with more than a
hundred years ago people contrast, has also been completely
different. What makes humans began a new way of life? This is
science and technology. Only promote the development of science
and technology human process. it can to make human life better. All
the technological advances of the discoveries and inventions to
make human become stronger. People are enjoying the great
benefits brought by the technology at the same time, also gradually
realized that science and technology is a double-edged sword.

3. "Technological development more
good than harm" .
If the "science and technology development is more good than harm"
this sentence is in doubt, then we do not have this right, because of
the disadvantages of the development of science and technology is
real. The world science and technology development brings
disadvantages throughout all aspects of our lives.

4. Technological development brings
drawbacks
1. Modern science and technology for all-round human development
caused a certain degree of distortion , which is manifested in social
relations, spirituality and ethics in three dimensions.

5. Technological development brings
drawbacks
 First of all, the development trend of science and technology is
potentially destroy the power of human social life.
 Secondly, the destructive power of science and technology, but also
in its constant attack and destruction of human life, which is
concentrated in two points of mankind, the Internet and gene
technology. Internet warriors already announced, to the network
becomes a living, but , when the virtual real alternative, as a social
human existence disappears. Look gene technology, life science
cure diseases, but on the other hand it is the intervention of nature,
produce more perfect human, but GM is perfect whether human or
high-tech ? products Today, changes in gene technology inherent to
human nature more direct impact on the human spirit home last line
of defense - ethics, science and technology round distortion of
human society, is to destroy the foundation of our society and the
spiritual world.

2. Environmental pollution
Development of chemistry allows us to get an unprecedented ability to
transform nature. Our chemical synthesis technique is that we made
the nature of this stuff does not exist, but now we have been plagued
by white trash, was poisoned by chemical contamination.
Development of oil exploration technology is greatly accelerated the
pace of human progress we have been able to exceed the speed of
sound, but it also brings a lot of troubles too many wars, but also
makes the Earth began with a fever.

3. Accelerate the extinction of species
This is caused by the killing of the pollution of the environment and
human. It belongs to the development of science and technology.

8. Technological development brings
drawbacks
4. Personal safety can not be guaranteed
There are tens of thousands of crime in a day on average. But the
criminal means most of modern science and technology. Especially
the gun crime, it is to let ordinary people impossible to guard against.
And since the second world war we can see, with the development
of science and technology, damage and loss caused by the war to
now far more than before comparable. There may even cause
human extinction.

9. Technological development brings
drawbacks
5. Human physical watered down
With advances in technology , gas cars, trains, planes and other modes
of transport emergence of mankind has undergone major changes in
daily life , humans have not always rely on their own two legs, so
now the human physique and before compared already can not be
compared . And this situation is likely to continue to develop people's
limbs atrophy, the emergence of a new form of humanity .

10. Technological development brings
drawbacks
6. Biochemical hazard
Emerging pathogens emerging, many of the harmful bacteria have
been far more than the previous destructive bacteria . This is due to
the rapid development of medical technology to speed up the virus
variants . The development of science and technology has not kept
pace that virus variants speed. maybe one day mankind will perish
certain a great plague.

11. Technological development brings
drawbacks
7. Global Warming
Advent of the automobile greatly facilitated our trip . But at the same
time more and more car exhaust amazing amount of exhaust ,
causing the greenhouse effect worse. When it comes to global
warming , some people may ask, in the end true or false, I can only
say that media coverage may be false , but the continuous melting
icebergs is true, shrinking glaciers is true, the data is not can be
deceiving .

12. Technological development brings
drawbacks
From 1980 to 2010 , with the car in people's lives play an increasingly
important role , CO2 emissions from transport increased year by
year the proportion has reached a point where nearly one-third of.

13. Technological development brings
drawbacks
8. Damage to the ozone layer
Air conditioning makes us cool in summer and warm in winter, to
improve human comfort, but also bring us what -- indoor air quality,
reduce the human body immunity, the ozone layer damage, we are
comfortable and violates the rights of other living creatures.

14. Technological development brings
drawbacks
 The discharge of large quantities of freon in the ozone layer
destruction. According to statistics, in twentieth Century at the end of
the 50's to 70's found that ozone concentrations had a tendency to
decrease. In 2007, the ozone hole area of only 25000000 square
kilometers, in 2008 the formation of the Antarctic ozone hole area
has reached 27000000 square kilometers. In 2009, covers an area
of 28000000 square kilometers.

15. In conclusion
In short, the rapid development of science and technology has two
sides of human life, there are both advantages and disadvantages,
the key is to grasp the scale, make the beneficial aspects more
prominent at the same time the drawbacks to a minimum, only in this
way can the harmonious development of human beings. People
don't do the masters of nature, but nature. When we are still indulge
in elaborating on iPhone brings us the perfect experience, always
enjoy it when we are in discussion of cloud computing, the concept
of Internet of things, when we are happy, and the space shuttle
missions to the moon, perhaps we should calm down, carefully
examines the high new technology of explosive development may
bring disaster to the human, perhaps this disaster is influence
character by environment formation, pulsed crisis more pleasure
may not be as the financial crisis, but it will probably come, perhaps
it has come......
