There are many ethical concerns when it comes to the topics of cloning and genetic engineering. There are two sides to every argument, and this is no exception.
Pro:
Genetic engineering and cloning can be beneficial to the human race. We can genetically modify crops to grow bigger, we can modify livestock to improve production, the benfits go on and on.

Con:
What gives us the right to manipulate natural processes. Genetic engineering can go far, allowing parents to select the traits they want their children to have and eliminate negative traits, an extreme case of predjudice.
