The use of Genetic Engineering on plants, crops, and food has also created a great debate among scientists and citizens.
First, in terms of plants and crops, Genetic Engineering can cause widespread crop failure. When a farmer plants genetically engineered seeds, all the seeds have identical genetic structures. Thus if a fungus, pest, or virus grows which can attack this certain crop, there would be a widespread crop failure. The wind, insects, and plants can all carry genetically changed seeds onto close fields and land. Once normal plants produce pollen, they can cross polinate with the genetically engineered crops. Thus all crops, organic and non-organic, are threatened by contamination. Also, this contamination is different from other kinds of pollution because once the genes are out, they cannot be recalled. Genetic Engineering of plants and crops also use a promotes the use of hericide. Herbicides are known to be responsible for great illnesses in farm workers. Herbicides can also contaminate water supplies and kill all the weeds in a field, thus lowering biodiversity.
Also many genetically engineered crops have Bacillus thuringienis (Bt)-toxin genes on them. With this GE material, helpful organisms such as ladybirds, bees, and butterflies are killed. Also if any Bt plant remains fall back to Earth, earthworms and other organisms who live in the soil are threatened. Furthermore, the build up of Bt toxin resistance threatens to stop the effectiveness of insesticides and this deprives the natural ecosystem of one of its pest controls, thus making the restoration of equilibrium difficult after the ecosystem has been disturbed by an abnormality.
Thus do we want these harmful genetically engineered products in our food, as well as these products destroying our agricultural system. We certainly do not. Genetically engineered food has not been fully tested and it is harmful because it uses material from organisms that have never been part of the normal supply of human food. GE can also cause unknown mutations in an organism, which can cause food to contain higher toxins in it. People can also have allergic reactions to genetically engineered food.
Many steps gave been taken to try to stop the distribution of genetically engineered food, but it simply is not enough. Recently, on May 3rd, 2000, the Federal Government and the FDA (Food and Drug Administration) announced new guidelines for the manufacturers of genetically modified foods. The new guidelines include a mandatory system in which the FDA must be notified about GM (Genetically Modified) foods and a voluntary system for labeling foods already in stores. This voluntary system angers many environmental and food safety groups because they do not think that it is good enough. They believe that it is necessary for all food distributors to notify customers when they are buying GM food. Andrew Kimbrall of the Center for Food Safety said of the new regulations, “FDA has announced a new policy which is really their old policy. You notify us you’re going to put the food on the market, but we’re not going to require safety testing, we’re not going to require labeling, and so you can go ahead, and the consumer will still not have a choice to avoid these foods if they want to.” The FDA argues that all tested GM food was found to be as safe as the original food. But how is the FDA certain?
Today, over 70 % of all food on grocery store shelves is genetically modified. Popular foods such as Doritos and Bugles are just a few of the GM foods. Many critics have labeled GM foods as “Frankenfood.” Should there be madatory labeling? I believe that this must be done in order to ensure the safety of people. It may be beneficial in cost to use GM foods. But if people begin to die, it certainly will not be worth it

How cutthroat is the engineering competition at ucla and ucsd compared to uc davis and cal poly slo?
Question by SkyO: How cutthroat is the engineering competition at ucla and ucsd compared to uc davis and cal poly slo?
In undergraduate engineering what is the competition like? Are they overall the same or is ucla full of uber geniuses compared to slo? How hard are the professors on grading? etc etc
Any comments, opinions, and anecdotes are helpful
and if it helps, I’m not one of the brightest students in high school
weighted gpa 4.19 (right under ucla avg for all freshmen)
AP US 5, AP World 5, AP English 3
sats 1990
act 31
math 2 800
us history 750
and I know most freshmen engineers have stats better than mine
So what is the competition like at these schools relative to each other? Is ucla and ucsd so hard in engineering that I would not have a college life cuz of the workload?
ok yeah that answer had good details t now im scared cuz if it turns out I don’t love engineering I’ll probably end up in medical school which i need a good gpa for
more opinions comments and experiences plz

I dont know about cutthroat competition, but i think UCSD would be an excellent choice. yes it is pretty competative but i think u have the scores for it. san diego has a very scientific and techy field market, anything from software developement, to nuclear physics, to building tracer bombs. it provides for great opportunity career-wise after u obtain your degree, its a very well established school. my dad works in computer science and looks at UCSD for interns and grad students all the time (in fact his offices are right across the street, lol)

How can I contract structural engineering services for a sculpture online and inexpensively?
Question by NixPhenom: How can I contract structural engineering services for a sculpture online and inexpensively?
I need to have the strength of a bent piece of sheet metal analyzed to see the maximum load it can support given some gauge of stainless steel. I would also like some process engineering services to determine the best way to assemble the final sculpture. I would like to know the best and most economical way to contract these services online.

Answer by Dave D
Go here to search the various structural engineering firms:-
https://online.acec.org/acecforum/acecLogin.asp
They ain’t cheap! Some sculptors have hired firms like these, but you need a wealthy sponsor such as the City of New York or whomever.
Or you could get yourself a copy of Solid Works and do your own analysis.
Or you could build a test piece and measure the failure load yourself.
Sculptors and civil engineers are not generally a happy mix. You will have your work cut out for you, as all sculptors do. The ways to stay on the right side of an engineer are as follows:-
1) All financial arrangements must be agreed in advance. Do not show up with no money and ask what to do next!
2) Always follow through immediately on things like returning phone calls, providing information and so forth.
3) Do not change anything once you have asked for an analysis to be performed. If necessary, do another analysis (at extra cost, of course) later.
Good luck – you are going to need it!

How do I formulate a hypothesis for an engineering project?
Question by Gulienne Pierre: How do I formulate a hypothesis for an engineering project?
I am building a device that could treat a certain disease….so how do I formulate a hypothesis?
Also, I’m not really sure how to collect numerical data, because it is a device …I need help lol sorry I am in high school. And how do I keep on journal for my project? What should I write inside of it??
I’m sorry if these questions may seem stupid, but this is my first engineering project and I have no guidance.
Best answer:
Answer by Nicky
This is all rather vague.
Your journal should directly record everything you do related to the project.
If you want numerical data, you must devise some measurement that will produce numbers. There should be two at least: some measure of the application of your device, and some measure of the results.
The routine hypothesis to test is whether or not your process had an effect, hopefully beneficial. For this, you will need to be able to compare one bunch with treatment, and another bunch without the treatment, and look to see if there is a significant difference between the two groups.

Modern Marvels – S11E53 Engineering Disasters 17 Part – (2/3)
Modern Marvels: It’s another chapter of complex, deadly and controversial engineering failures, using 3-D animation, forensic engineering experts, and footage of the actual disasters to understand what went wrong, and how disaster has led to improvement. In Sun Valley, California, weeks of record rain turn a crack in the middle of a street into a 200-foot long sinkhole. Months later, rain led to the Laguna Beach, California landslide, which destroyed 11 homes and caused millions in damage. On May 23, 2004, four people were killed when the roof of the new Terminal 2E at Charles de Gaulle International Airport in Paris collapses. Other disasters: the 1931 crash of Fokker F-10 passenger airplane with coach Knute Rockne aboard; the sinking of the coal ship Marine Electric off the coast of Virginia; and the blinding reflection of the new Walt Disney Concert Hall in Los Angeles.

There are many professional societies specifically for engineers and anyone working in specific areas or industries. IEEE, International Electrical and Electronic Engineering, is the largest engineering society in the world and covers a very diverse range of technologies, from power generation and transmission to semicondutors to automotive electronics and everything in between. ASM Intl (fka American Society for Metals) is for professionals in metals and materials industries, primarily metals but also polymers and covers extractive metallurgy thru to failure analysis, tons of technical information on alloy chemistry, mechanical/physical properties/corrosion, applications from aerospace to medical devices. and many others… SME, Society for Manufacturing Engineers. ASQ, American Society for Quality. AWS, American Welding Society.
