Controversy Over In-Vitro Fertilization.
Since the inception of in-vitro fertilization (IVF) in the 1970's, the topic has been one of great debate and controversy. In the past, it was mostly due to a lack of knowledge, and people's concerns over the general effectiveness of the procedure. In recent years there has been a new topic of discussion: whether or not it is ethical to alter the genes in harvested embryos before re-implanting these embryos back inside the mother's womb. Current technologies have made it possible to test for genetic disorders so that parents can decide whether or not they want that embryo implanted or not. This practice is not ethical, and drawing a line is simply too difficult. Such procedures should not be employed, and even the practice of in-vitro fertilization is questionable in itself.
According to the Grolier Encyclopedia of Science and Technology, one of the most common causes of infertility in women is a disorder in the fallopian tubes or oviduct, most commonly a blockage. IVF often enables conception despite such a blockage by creating what is now termed "test tube babies" (Grolier 31). Sadly, not everyone is able to have their own children. While most people see this as a curse, we live on a planet that is grossly overpopulated. The last thing we need is more people on it. There are more than enough pregnancies resulting from natural causes to sustain human life. Once the 1% of births that occur through IVF in the United States (CNN 1) is factored in, the population is boosted even more. In fact, since 1981, in the U.S alone, there have been more than 114,000 babies conceived with IVF. .
Charles Darwin came up with an inescapable conclusion regarding natural selection. Fact one: "Any population of a species has the potential to produce far more offspring than the environment can possibly support This overproduction leads to a struggle for existence among the varying individuals of a population" (Campbell 11).
