What are the potential risk of GM Crops?

Answer 1

One of the the biggest risks is that they will become weeds, since they are generally bred to be herbicide resistant, so that they can be sprayed broadly, with any non-resistant plants amongst them dying.
The other risk is that they will become dominant in the market place, since they are generally higher yielding than non-GM plants. Therefore any farmer groing the GM version will have better returns, those with non-GM crops will earn less, since their crop is more expensive to grow, and they will need to compete with the GM crop.
As more farmers adopt the GM crop there will be less genetic diversity for that particular crop. Less diversity means that any disease which successfully attacks the crop will have a more devastating effect.

Answer 2

the potential risks of gm crops are numerous
as soon as we release a genetically modified plant into the enviroment it then will begin to start crossbreeding with other plants changing the make up of the entire species for example farmer A plants farm A with gm crops, as does Farmer B with his farm only he uses regular crops animals carry seeds and pollen from Farm A to Farm B , which then also begins to grow genetically modified crops
or as easy as wind blowing seeds from one farm to another
the scientists and companies that work with genetically modifying seeds are 'playing god' in that they can re arrange the plant however they see fit and science and industry have often acted contrary to mankinds best interests
we must ask ourselves also where does it end if we can make corn that is resistant to only one pesticide or wheat that grows faster which are fantastic advances that could rid the world of famine we can also then see perhaps copyrights on plants where companies that invest money into this technology can claim to 'own' nature or then genetically 'modifying' animals and people , where should science draw the line or even if a line should be drawn in the first place

Answer 3

a) Plants exchange genes fairly readily. The big risk is that the "roundup ready" gene will cross over into some weed plant.
b) Insect-resistant and fungus-resistant plants produce more of the substances that make them resistant than would naturally occur in a plant. At these high doses, these substances may have some untoward effect on human beings.

Answer 4

to my knowledge mainly 1) allergies and 2) the GMO pollinate with regular crops and change their characteritics, and if they did have an increased risk of allergies or something, then it is now in the main stream crops. but im no expert. theyre a lot less risky than the people who are against them claim they are, their opponents are more just afraid of the unknown than anything.

Answer 5

IT HAS BEEN OBSERVED THAT NEW STRAINS OF PATHOGENS CAUSING DISEASES R BEING DISCOVERED AND THE PROBABLE REASON OR ONE OF THE REASON BEHIND THIS IS THE CHANGE WE BRING ABOUT IN PLANTS THRU CHANGING THEIR GENETIC CONSTITUTION IN ORDER TO HAVE RESISTANCE.SO THERE IS A RISK ALWAYS THAT A NEW STRAIN OF PATHOGEN MIGHT DEVELOP.AS SAID BY OTHERS I AGREE THAT THE SPREAD OF PLANT MAY B TO AN EXTENT OF WEED.THE CAPACITY OF PLANT TO DO PHOTOSYNTHESIS MAY CHANGE THE POLLINATION MODE .MOREOVER WE R NOT ALWAYS SURE ABOUT WHETHER THE DEVELOPMENT WE R GOING TO DO IN A CROP IS ALWAYS BENEFICIAL....THEY MAY HAVE ADVERSE EFFECT ON SOIL AND NEAR BY PLANTS.

Answer 6

there are some risks, like :
a)Bioavailability
b)Crossing with wild-type
c)Allergic reactions

try to think on this basis.
Good luck
