every year, millions of animals undergo painful suffering or death as a result of scientific research into the effects of drugs, food additives, cosmetics and other chemical products. while most people think animal testing is necessary, others are upset by what they see as needless suffering. this essay looks at some of the positive and negative aspects of animal testing.

many medical treatments and procedures have been developed from experiments on animals. since animals share many features with humans, scientists use animals to test the safety and effectiveness of newly developed drugs before pilot testing on small groups of patients. medical teams practice new operating techniques such as transplants on animals. without animal testing, many procedures or new drugs would be extremely unsafe.

however, many people are concerned that animals are suffering unnecessarily and cruelly. they do not believe that every new drug needs to be tested on animals, especially with the huge database of knowledge and modern computer models. they also are worried that many animal tests are ineffective, pointing out that any drugs have had to be withdrawn from the market despite extensive testing. they particularly feel that animal testing should not be used for non-essential products such as cosmetics, shampoos, soaps, and cleaning products. furthermore, some campaigners would like to see certain tests replaced and more humane methods used.

in many parts of the world， a traditional concept of family called four generations living together has been handed down for thousands of years. in old times， the eldest man usually dominated others without any challenge amid the overpopulated home. in comparison with modern society， such a place should be an effective habitat to keep greed and selfishness ，which is considered as born nature of humans， away as a consequence of helping each other and sharing property between family members under the supervision of the most influential man. however， over a thousand-year period those female members suffered extremely tough circumstances of s e x ual discrimination: they were in charge of childcare， household chores， farmingtopsoil clearing and planting， you name it. whats worse， they werent allowed to dine with men at the same table-leftovers filled up their bellies. conversely， in contemporary society， a growing number of females are fighting for more human rights， say， equality to males， and they are gaining ground! how to convince the fierce female tigers these traditions are their better destiny? no way!!!a better life can never be expected by only eliminating greed and selfishness. whereas it ought to be defined along with the following qualities: privacy respected， individual development， no s e x ual discrimination and a fair community with equal opportunities. in addition to my viewpoint， an appropriate way of education would probably a sensible solution to minimize the goddamn greed and selfishness in modern society instead of returning to the old society.

we sure live differently from our parents did decades ago. the changes are wide and profound. at the same time, we are facing challenges and problems unknown in the past. could we find solutions to problems created by scientific development? the answer seems to be no.

some of the most obvious problems caused by technological advances lie in the it industry. at a time when we did not have computers and electronic bank services, people took money with them and paid by cash. if they were stolen, only the amount they had with them was lost. but now credit cards are more commonly used in shopping malls and other places, crimes again us have become more serious and caused greater losses to people. a thief may tape the code of your credit card and make a copy of it. then he could safely withdraw all your money from an atm machine. crimes such as this are very sticky to solve because there is no witness and the surveillance cameras give little help to the police.

another example is the issue of information control with the media industry including tv networks and internet that give easy access to information without discrimination to people’s age. this has created a huge problem for parents and schools because teenage people are particularly vulnerable to adult materials and information violent in nature. in the past, when most information came in the form of print, it was relatively easy to control what children read. when a parent put away a book unsuitable for children, they were cut off from the source of information. with computer parents could use software to filter bad web sites but could not prevent new ones from appearing every day.

people are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful. even with the little progress we have achieved, we find ourselves defeated by new problems with greater complexity and in wider scope.

in conclusion, developments in many fields of our life have brought us both benefits and problems. developments in the banking industry give us greater convenience but making us targets of computer-based theft. changes in media industry expose young people to inappropriate information difficult for parent’s control. however up until now, we have not successfully found permanent solutions yet.
