If in the past(a) nature was the only one which could influence the changes in organisms , right away hatful can do it as wellIn to satisfy their ask , people have discovered that they could genetically modify animals and plants . On one hand , genetic engineering and cloning can be precise 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 with umpteen viruses which are currently available by inventing new sl ipway of treating them . disdain many positive features , there are or so blackball consequences connected with genetic engineering . For example , actually 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 awe or chicken .
