If later on, scientists discover that the previously unwanted gene is needed in order to prevent some disease or some other type of disaster, the scientists may not be able to gain the lost gene back. Since biotechnology does have the power to replace unwanted genes with wanted genes, a beneficial gene could be lost. At present, scientists can not create new genes, they can only implant or change existing genes. Another problem with genetic biotechnology is it has been rapidly accepted into society and used even though very little is known of the long range effects of genetic biotechnology. Even though the human race has been dabbling in genetic technology for quite a while, people still do not know exactly how all of their experiments in genetics will end.
Genetic biotechnology is still a very new science and perhaps too many people rush headlong into it.
Another common misconception about biotechnology is that it will solve the problem of world hunger. While biotechnology may be able to increase yield outputs while lowering farmers' costs, it may not help to solve world hunger at all. Though many people think that higher outputs of food will help to feed the growing population, the amount of food may not be the problem. As a matter of fact, if more food is made available to the people of the world, population might increase even more rapidly. Genetic biotechnology may have many benefits to mankind, but mankind also needs to consider the drawbacks of the new technology.
