If in the yesteryear nature was the only one which could influence the changes in organisms , directly mess can do it as wellIn to satisfy their take , people have discovered that they could genetically modify animals and plants . On one hand , genetic engineering and cloning can be very helpful for mankind because they would allow people to puzzle clones of animals instead of raising new animals in the farms . Genetic engineering could also help the people to fight w ith many an(prenominal) viruses which are currently available by inventing new slipway of treating them . disdain many positive features , there are just about blackball consequences connected with genetic engineering . For example , very particular(prenominal) research needs to be conducted on the quality of genetically modified products which people consume because they might non all be appropriate for consumption and could cause diseases . Regarding cloning of animals , not all of the people would like to buy the meat of cloned overawe or chicken . Labeling of these food products would have to be very closely monitored , while this cannot always be easily achievedThe loss of gay cloning is still very contradictory from the in effect(p) point of view because when creating a human clone , a scientist would take a place of God to some coat .
