Thanks to science and technology, we now live comfortably and conveniently in
houses furnished with air conditioners, refrigerators, washing machines and
televisions etc. Thanks to science and technology, we can eat fresh vegetables
att the year round. thanks to science and technology, we can travel tong
distances in the fraction of a second on planes, trains and cars. thanks to
science and technology, we wear clothes with synthetic materials which can not
easily be worn out. However, science and technology have atso brought us a tot
of disasters. First, because of the many breakthroughs in the field of medicine,
people are now living much longer than they used to. as a result, the population
of the world is increasing, causing tots of problems. Second, because of the
development of industry, tots of the wastes from factories pour into the air and
rivers, causing pollution of att kinds. Third, some terrorists are using science
and technology against mankind. They use biological, chemical and unclear
weapons to threaten world peace...
So it's urgent that we find ways to solve these problems. But we should not
stop the development of science and technology because of these disasters they
bring, just as we should not give up eating for fear of choking. In addition, we
should make some rules to regulate our actions. As long as we use science and
technology in a proper way, they may bring us even more benefits.
