Fact Sheet: Pros vs Cons

Gm Foods Benefits Disadvantages Food

With all of the controversy around genetically modified (GM) foods, sorting through huge volumes of information can seem like a daunting task. Many members of the public are asking questions about GM foods and they are also raising concerns about the effects these foods may have on their health or the environment. There are different advantages and disadvantages of GM foods, although to what extent they can help or harm humans and the environment is a debatable aspect of this technology.

Benefits Of GM Foods

A proposed benefit of GM foods is that they can potentially produce higher crop yields, which could help by feeding more people in developing countries. They are also cited as more economical, despite the initial higher cost of the seeds. The rationale is that they reduce the need for pesticides and herbicides as well as reducing the manpower needed to successfully grow the crops, which should translate into improved financial gains.

Improved food quality is another benefit associated with GM foods. A tomato, for instance, can be engineered to stay fresher for longer, thereby extending its shelf life in the supermarket.

Yet another benefit that is believed to occur from GM technology is that crops can be engineered to withstand weather fluctuations and extremes. This means that they can provide sufficient yields and quality despite a severe, poor weather season.

Another benefit is that GM foods can be engineered to have a high content of a specific nutrient that is lacking in the diet of a local population group. The vitamin A rich 'golden rice' is one example of a GM food that has been engineered to have high levels of a nutrient.

Issues With GM Foods

A worrisome issue in GM foods is the ability of a food to trigger an allergy in humans. Some of the genes used in GM technology might be taken from a food that causes allergies in some people. Inserting that gene into another organism could cause the host organism to express that allergen as a trait. Alternately, a new allergen could be produced when genes are mixed across different species.

Another potential downside to GM technology is that other organisms in the ecosystem could be harmed, which would lead to a lower level of biodiversity. By removing one pest that harms the crop, you could be removing a food source for an animal. Also, GM crops could prove toxic to an organism in the environment, leading to reduced numbers or extinction of that organism.

Given that some GM foods are modified using bacteria and viruses, there is a fear that we will see the emergence of new diseases. The threat to human health is a worrisome aspect of GM technology and one that has received a great deal of debate.

Using The Fact Sheet To Make An Informed Choice

There are many other potential benefits and risks to GM foods, which you will likely learn about as you investigate the topic further and decide whether or not you want to support or avoid GM foods and related technology.

Reading a brief fact sheet is a good way to familiarise yourself with the purported benefits and issues related to GM foods. In this way, you can equip yourself with an overview of the knowledge needed to make an informed decision about GM foods and how they will affect your life.

The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, start.

It's called, We all have a choice, either we buy into it or not! Stop letting big pharma and governments push you around. Stand up to them. It's time we all stood up to the government.

your all forgetting that satan approved GMOs in His book of revelations which you would know if you were at the satan-lizard cross over meeting in the White House last tuesday... if satan approves it then i guess it means we should all approve it because satan has given you everything you could want in this world so we should bow down to him. the lizards are ok i guess coz at least they collaborate with satan. Lizards and satan are pro GMOs!

My Lizard King, it is time for our reign on this weak planet with the ever increasing amount of 'GMOs,' as they call it. Let us rule the comment section and this world, together, forever. Allah ackbar.

Gmo's are interuupting the spirtual world and disrupting the connection between true Pagans and the god and goddess. My powers and magic are weakening since i have begun eating genetically modified foods. I now have to harness even more power from the moon to charge my crystals for my rituals. Wicca society is now being threatened by these gmos and I must warn you all, us Wiccans will not remain silent. We will rise above you all.

I have an assignment and this is the article I chose to review it's credibility. Would you mind linking me the sources of where you found these facts. I would need them as soon as possible please?!

Do you believe that we could further develop GMO technology and if so, how
Dr Robotnic - 3-Jul-17 @ 10:58 AM
(I think religion should be put out of this issue, seeing it's a sensitive topic)

If god is real then he would accept all his children. Including the lizard people and the angry demimgod Xenu. And I think he would love his GMOs as well because there are loads of trans and gay people who want to be something they aren't. So why not let the GMOs free and let them be what they choose
capitalistic bastard - 27-Apr-17 @ 1:25 PM
Okay seriously calm down for one we don't know if god is real or notbecause we don't have solid proof except for "man's" word and we hate Muslims but Arabic and Muslims wrote the bible and two gay is not a sin if god is real then we know he would love all his children for who they are. Drop the mic P.S I'm a 13 year old and i outsmarted all of you.

Attention. I have made another mistake. I assure that this will not happen again, and I thank you for your understanding. The previous username was intended to be 'feministchristian222 IS WRONG' yet this was not accepeted and I was not informed, meaning that the username appeared as 'feministchristian222'. I hope you can find it deep within your heart to forgive me. Yours sincerely, fc222 IS WRONG

this is a very cool they i love it its amazing

This is the nickname I meant to set in my previous statement. I apear to have made a mistake, which will not happen again
feministchristian222 - 29-Mar-17 @ 2:35 PM
In this essay, I aim to explain why feministchristian222 has lied to you all. My first point is that God is decisively not real. After spending my spare time at Cambridge disproving the bible, I have conclusive evidence to say that god is not real. This therefore, through logic, means Christians aren’t real. Do not believe feministchristian222 as she is purely a figment of your imagination, not real in the slightest. I am deadly serious. Just try to stop thinking about her and it will all go away. Secondly feminism is stupid as it is obvious to me that men are clearly superior to women. This argument means you are not worth listening to even if you are right. In conclusion, I feel that you are wrong, and I, as always, am right.
feministchristian222 - 29-Mar-17 @ 2:31 PM
I agree with feminist christian. My son is now gay.
Heavenlord666 - 29-Mar-17 @ 2:31 PM
gm crops are against the bibles rules. we should never mess with the eternal one's plan for us. if he says that normal rice should make people blind, they were meant to be blind. these chemicals in the crops are turning our children gay and making them sin. i eat food we christians were sposed to eat, given by god, fresh and tastie. i believe gm crops are the start of the rapture and satans way of tempting us folk. i read a tumblr post that said gm crops are scientifical experiments gone wrong and that sterring clear of them is the only way to get to heaven. i hope yall agree.
feministchristian222 - 29-Mar-17 @ 2:18 PM
How do you know how it will react with different bodies eating food that is genetically modified.My thoughts are that it creates more product which in turn creates more money so let's push it to whoever will accept it and doesn't know any better. My question is--- how will it affect humans in the long run, or is it affecting them already but we are not told of the results because the bottom line might be in jeopardy.!!!!

I think this may be harmful because it may be too early for us to know the long-term effects which may be bad

GMOs are the best things since sliced bread
super sanin - 7-Dec-16 @ 6:05 PM
well I believe that no matter what we say or do the government is still going to create and keep producing GMO'sbecause they believe that by doing that we will have a better world
