14 April 2008 Jery Stedinger Lecture 33 Greenpeace–Say no  to genetic engineering While scientific progress on molecular biology has a great potential to increase our understanding of nature and provide new medical tools, it should not be used as justification to turn the environment into a giant genetic experiment by commercial interests. The biodiversity and environmental integrity of the world's food supply is too important to our survival to be put at risk. Genetic engineering enables scientists to create plants, animals and micro-organisms by manipulating genes in a way that does not occur naturally.These genetically modified organisms (GMO) can spread through nature and interbreed with natural organisms, thereby contaminating non 'GE' environments and future generations in an unforeseeable and uncontrollable way. netic-engineering _ full/international/photosvideos/photos/ corn-grenade-the-winning-imag.jpg

14 April 2008 Jery Stedinger Lecture 33 Genetically Modified (GM) Organisms  Most common genetically modified (GM) organisms are crop plants.  But the technology has now been applied to almost all forms of life,  from pets that glow under UV light to bacteria which form HIV- blocking "living condoms" and from pigs bearing spinach genes to  goats that produce spider silk. GM tomato first appeared in the US in 1994 . The furor that surrounded  GM technology did not erupt until Feb. 1999 due to a controversial  study that suggested that a few strains of GM potatoes might be  toxic to laboratory rats. Those experiments, subsequently criticized  by other experts, were carried out in Scotland by biochemist Arpad  Pustzai.

14 April 2008 Jery Stedinger Lecture 33 Genetically Modified Foods:  Are They a Risk to Human/Animal Health?  By Arpad Pusztai Information is scarce about health hazards, such as toxicity in  genetically modified (GM) crops. So how can public make informed decisions about GM foods? The lack of data is due to a number of reasons, including: 1. It's more difficult to evaluate the safety of crop-derived foods than individual  chemical, drug, or food additives. Crop foods are more complex and their  composition varies according to differences in growth and agronomic  conditions. 2. Publications on GM food toxicity are scarce.  3. The preferred approach forf industry has been to use compositional  comparisons between GM and non-GM crops. When they are not  significantly different the two are regarded as "substantially equivalent.”

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
