The Search for the Perfect Child

"Designer Babies" is the term Being used by the media to describe the future of modifying or selecting our children's genes for desirable characteristics (medical and cosmetic). Are things getting out of hand with our research into genetic processes?


Okay, so there has been huge controversy over the issue of designer babies. Some people are for it, some are against it. But before taking any sides, one must always consider the facts.

A "designer baby" is a baby who's genetic make- up has been artificially selected to ensure the absence of presence of certain characteristics. How is this done you may ask? Using preimplantation genetic diagnosis, a technology that has been available to paying couples since at least 2001. Preimplantation genetic diagnosis, or PGD allows parents to screen out embryos that have inherited genes for certain serious diseases like cystic fibrosis, muscular dystrophy, hemophilia and many others. The process involves fertilizing eggs in a lab , and when the embryos are about three days old, a single cell is removed and analyzed. Any embryos with abnormal chromosome counts are discarded and the healthy ones are then implanted into the womb (in vitro fertilization or IVF).

The main controversy is not about screening embryos for these diseases, but using PGD to select the sex of a child. In fact in a 2006 survey conducted by the Genetics and Public Policy center at John Hopkins University it was found that 42 per cent of 137 PGD clinics in the U.S. offered a gender- selection service. Fertility Institutes - a PGD clinic operating in the U.S. and in parts of Mexico states that they have had over 3 800 cases of gender selection with a 100% success rate. Many countries have already banned gender selection including Canada, the U.K. and Germany.

On March 3, 2009 Fertility Institutes announced that they have the technology to allow parents to choose their babies hair, eye and skin colour. Selection of traits perceived to be desirable will diminish the variability within the gene pool, and we all know the importance of this diversity.

These are just the facts. Have an opinion yet? I do. I can't imagine what kind of parent would want to choose even the sex of their baby- never mind how their baby looks! Can you imagine what the world would be like if people chose which sex they're child would be? Countries like India and China where male children are preferred would have a while generation of mostly male babies. The balance of the female/ male populations of the world would be completely thrown off. It could result in thousands of single men because there aren't enough woman, or vice versa.

Then imagine parents choosing the characteristics of they're children. With PGD and IVF services costing upwards of $10 000 children would become a financial investment. Just picture the obsessive parents- the kind you find screaming their heads off and fighting with the referee at their children's sporting events. Or the parents that push their kinds so hard in academics. These parents pour all of their hopes and dreams into their children...what would happen if they also poured all of their money into creating them? Let's say perhaps a child was designed to be more athletic. That kid would be forced into sport- weather they liked it or not because they wouldn't be just a child anymore, but an investment. Encouraging phrases would change from "You can do it!" to "You have to do it- you were designed for this! I paid good money for you!"

If people invested so much money into creating the perfect child- parenting would become materialistic instead of loving. Parents wouldn't just love whoever they had for the gift that they are, but only love the best that they could create. What about people who wouldn't have the money for such procedures? Society would become divided between those that could afford perfect babies and those that couldn't. Would or should a deaf parent who embraces they're condition be allowed to select a child unable to hear? Where would the line be drawn on how many decisions parents could make for their children on how they look or what they are capable of?

The technology of PGD was originally developed to help couples have healthy children free of genetic diseases. But let's face it- Traits are not diseases. We can't let the miracle of having a child turn into flipping through a catalogue and deciding on exactly what you want. The world is what we make of it and why would anybody want to make a world that is already so obsessed with perfection that girls would starve themselves to look a certain way, even worse?








The Pope himself condemned "designing babies" on February 23, 2009 as an "obsessive search for the perfect child" On march 4 , 2009 , a day after the Fertility Institutes announced their technology to choose a baby;s eye, skin and hair colour, they reconsidered. The project was scraped because of "public perception".

Man Up Humanity! Take Responsibility





Many Scientists consider humans as the most invasive species, as humans greatly change an environment and impact living things that reside there. Are we being stewards of the world? Take a look at an issue in which human intervention has positively or negatively affected the biodiversity of our ecosystems.









In my opinion, humanity is an invasive species and thus are terrible stewards of the world. Any plant, animal or microbe that is not native to a given ecosystem which is likely to harm the ecosystem, human health or cause economic losses is an invasive species.(greeniacs.com) Humanity, being the most mobile species, can live anywhere on earth, and everywhere we go we harm the ecosystem. Through pollution, over harvesting , the introduction of invasive species and habitat destruction, humanity affects the biodiversity of every ecosystem. By affecting this diversity of living things, we jeopardize the species' existence, and in turn the entire ecosystem and all that is in it, including humanity. As stewards we are suppose to be taking care of our planet, yet we do so many things to harm it.








Pollution is a Major factor affecting the biodiversity of our world. The burning of fossil fuels have lead to an increase of green house gasses and the chemicals, toxins and waste we release into the environment poison countless ecosystems. Because of this, many species are being harmed, even endangered and extinct. The Irish Char, a fish that was present in sizable amounts in the early 1980s was extinct from Irish lakes and rivers by 1990 due to excess amounts of phosphorus from agricultural run offs.





Not only does humanity poison ecosystems and habitats. we destroy them too. Habitat destruction affects all animals in the ecosystem as their homes are destroyed through deforestation, wetland drainage and the conversion of habitats for our growing agricultural needs. Plant species and constantly destroyed for agriculture, firewood and building materials. How can anyone expect something to live when heir habitat, their homes, no longer exist?





As humanity's population grows so does our demand for food, which leads to over harvesting. The biodiversity of our planet is being lessened every year because we consume resources faster than they can be replenished. It is estimated that 70% of the world's important fish stocks are over exploited, paper use has grown six times since 1961 and fresh water consumption has tripled since 1950. (BBC) Commercial fishing catches more fish than we need, faster than they can reproduce and replace what was taken. If we continue over harvesting like this many species will cease to exist. Does this sound like we're taken care of the earth? I don't think so!





Humanity is the most mobile species and wherever we go, we bring alien species with us, whether it be intentional, like the small Indian mongoose, or unintentional like zebra mussels, it still happens.





Zebra mussels, native to the Caspian Sea region of Asia, were likely brought into the Great Lakes area accidentally on the hulls or in the ballast water of vessels. The Zebra mussels spread rapidly, clogging pipes, cooling systems of boat engines and boat hulls and devouring most of the available microscopic food supply. Their sharp edges cut the feet of swimmers in the lakes as well. Governments are working feverishly to educate boaters so the mussels don't spread any farther.




Though the introduction of this invasive species was done by accident, the introduction of the small Indian mongoose was not. The mongoose (nominated as "100 World's Worst Invaders") is native to Asia. The small Indian mongoose has however, been introduced widely to the West indies, Mauritius, Hawaii and several other islands to control rats, snakes and other pests in sugarcane and other crop fields. However, the mongoose started killing domestic poultry and indigenous animals. The mongoose has been held responsible for the extinction of several animals. Oh, and did I mention that it's also a vector for rabies? The mongoose of course is completely innocent sense it was humanity that is responsible for introducing this invasive species in the first place!



All of this greatly affects the biodiversity of our world. As stewards of the earth, humanity is doing a terrible job. We are suppose to be taking care of our planet and everything on it, yet we are ruining its biodiversity by killing and endangering so many plants and animals. Biodiversity is essential to the strength of the entire ecosystem. I hate to break it to humanity, but we're doing a crap job at caring for our world. Humanity has got to get educated on what we are doing! Take on responsibility for our actions.W must take care of our one and only planet earth if we intend to keep living on it, and that includes taking care of everything that resides here! Man (or woman!) up humanity!
