Thanks to technology, we now live comfortably and conveniently in houses which are furnished with air conditioners, fridges, washing machines an so on. Besides, because science and technology is developed quickly, we can travel long distances in the fraction of a second on plans and in cars. However, because of the breakthroughs in the field of medicine, people are now living much longer than they used to. As a result, the population is increasing, leading to lots of problems, such as environmental pollution. Therefore, as long as we use science and technology in a proper way, they may bring us even more benefits. Thank You $
