The Pros and Cons of Biotechnology
Transcript of The Pros and Cons of Biotechnology
- Xenotransplantation - transplanting animal organs into humans instead of organ donors
- Therapeutic Milk - GM cows produce a milk to help nourish premature infants.
- Inserting vital vitamins and minerals into foods for human consumption.
- Golden rice - A variety of rice (oryza sativa) produced through genetic engineering with beta-carotene (pro-Vitamin A) in its edible parts. Additional Resources http://www.webmd.com/food-recipes/features/are-biotech-foods-safe-to-eat

There are also concerns over the safety, possible food allergies, environmental impact, and the critic slang "playing with nature."
Plus biotechnology products have only been around since the 1990s. Additional Resources http://www.webmd.com/food-recipes/features/are-biotech-foods-safe-to-eat

Benefits The Pros and Cons of Biotechnology By Keenan Thungtrakul Horticulture GE crops have increased nutritional value, pest resistance, nitrogen fixation, and ability to withstand a harsh environment. Transgenic plants have new colors and can grow in areas naturally too hot or cold, and there is an increased demand for genetically modified crops advantageous to the environment. Environment The use of biotechnology has allowed for cleaning up contaminants and protecting endangered species. An example would be the recent BP oil spill. Oil-eating bacteria were dispersed into the Gulf of Mexico to help clean the water of the thousands of barrels of crude. New bio-remediation processes allow for safer cleanup without using harmful chemicals. Effect on "natural" populations Genetically modified organisms if released into the environment can transfer those modified genes to "natural" populations when they mate and reproduce.
To remedy this problem, terminator genes have been used to prevent the GMO from being able to reproduce and spread the modified genes on to local populations. Finances and Ethics Currently the production and use of transgenic organisms are highly expensive due to the need for workers to actually go into the organisms and take out the genes to be replaced and mass-producing these organisms is currently not efficient with the current technology.
The cost of creating and utilizing biotechnology products is higher than the use of normal products, due to the need of manual labor to modify the genetics. There are also concerns over the safety and ethics of incorporating GMOs into food for human consumption, and the use of a GM corn, Starlink, is not yet approved by the government for human consumption in taco shells. I think that biotech will help revolutionize the way we look at the future. It will be easier for people to be able to get the nutrients they need while eating the foods they love. Babies will be able to get essential nutrients easier without risks to their health. I know the controversies that come with biotechnology, but I think that the pros outweigh the cons. The construction of the colonization ship planned by my friend and I will involve the construction of a biolab for researching new specimens on other worlds and a Genome Log for all DNA to allow for cataloging and easier replication of organs for military injuries.
