Unit 5 - Designer Babies

In today's world, many people are interested in perfections, be it themselves or their children. With genetic research and experiments becoming increasingly successful, many options are opening up to people in terms of changing their genetic sequence, for cosmetic reasons, or to prevent certain genetic diseases. With the recent upgrades in technology and scientific advances, we are now able to "design" our babies to a certain extent. Advanced reproductive technologies allow parents and doctors to screen embryos for genetic disorders and select healthy embryos. However, these advanced reproductive technologies prevent normal childbirth and conception. These embryos are basically "test tube babies", and are treated like science experiments.At the moment it is only legally possible to carry out two kinds of advanced reproductive technologies on humans. The first involves choosing the type of sperm that will fertilize an egg. This is used to determine the sex and the genes of the baby. The second technique screens embryos for a genetic disease: only selected embryos are implanted back into the mother's womb. This is called Pre-implantation Genetic Diagnosis or (PGD).

 The current utilization of ARTs (advanced reproductive technologies) is strictly for medical use, which is understandable because all parents want healthy babies. However sooner or later the fear is that we may be able to use genetic modification technologies to modify embryos and choose cosmetic characteristics. This is something that I cannot agree. Of course just as parents don't want their children to have diseases, they don't want them to be ugly, but for them to be able to choose everything down to the colour of their eyes is going to far. If this happens Mendelian Genetics and heredity will be obsolete. No longer will anyone be created in God's image. People will be born in test tubes, not in their mother's womb. In the future there may be social problems for people not born with certain traits. One day there might be a race of super humans who look down on people that don't share their special traits. On top of all this, the Church does not support any scientific modifications to embryos. People should just be born the same way they were since the beginning of time. Who knows, maybe one day these genetic enhancements will have greater problems in terms of health than normally born babies.

Unit 2 Bioblog - BAP (Biodiversity Action Plan)

          The Biodiversity Action Plan (or BAP) is an internationally recognized program that has been adopted by countries around the world to help preserve biodiversity in the environment. Australia, St. Lucia, Tanzania, the UK, the U.S., and Uzbekistan have taken the lead in biodiversity protection.
                                                                                                                                                                           

Australia
Australia's BAP plan involves preserving the Great Barrier Reef. Even though the GBR is one of the healthier reefs in the world, there is still concern over environmental damage that is caused by poor water quality from land use practices.








                                                                                                                                                                         
St. Lucia

The BAP concerning St. Lucia is in place to deal with the large number of tourists visiting the country. The problem with tourism is the fact that the carrying capacity for human use and water pollution discharge of sensitive reef areas was exceeded by the year 1990. The St. Lucia BAP features significant involvement from the University of the West Indies. Specific detailed attention is given to three species of threatened marine turtles, to a variety of vulnerable birds and a number of pelagic fishes and cetaceans. In terms of habitat conservation the plan focuses towards biologically productive swamps which have been put under governmental protection since 1984.

                                                                                                                                                                      
Tanzania

Tanzania has really taken a step to develop it's BAP initiative. Almost a quarter of the country's land has been set aside as a wildlife reserve. The government has opened the country to tourists which are invited to experience the beauty of the national parks. Tanzania is one of the most wild countries on earth as it holds much over 20% of Africa's mammal population. The only remaining issue that BAP has to address is the increased use of Lake Manyara. Since the 1950's the increased human usage has put continuity of Lake Manyara in question.



                                                                                                                                                                     

The United Kingdom

The UK BAP not only targets the species residing within the lands of the UK, but also marine animals and migratory birds. On August 28, 2007, the revised BAP for the UK has listed 1,149 species and 65 habitats that need conservation and greater protection. The list includes the hedgehog, house sparrow, grass snake and the garden tiger moth, while otters, bottlenose dolphins and red squirrels remained in need of habitat protection.

                                                                                                                                                                     

The United States of America

26 years before the first international biodiversity convention, the US had already launched the Endangered Species Act. The act created concern for many at-risk species and because of this the US longest tracking record and best species protection program of any country. Today there are over 7000 species that are "at-risk" in the US, and recovery plans have already been ratified for about half of them. 

                                                                                                                                                                          

Uzbekistan

Five major habitat areas have been identified under Uzbekistan's BAP: wetlands (i.e. swaps), desert ecosystems, steppes (plains), riparian ecosystems (rivers), and mountain ecosystems. Over 27,000 species have been inventoried in the country and are under close observation. The main threats to biodiversity in Uzbekistan are a result of over-population and are also related to agricultural intensification.
