my opinion

personally I think that gm foods should be made extinct , yes they keep up with the growing population but couldnt we put more organic food farms up in place and couldnt we grow our own fruit and vegtables in our back gardens at least then we know were its all come from



The genes that are put in gm foods can transfer into humans and may harm us with eating these foods we may be harming not only us but the world



As these foods are mass produced the machinery that goes into the watering ,fertilising (ect.) these plants could be destroying he planet by all of the co2 emissions that are being let off when we could easily put abit of elbow grease in and there we are a mini supermarket in your own home. And on top of that theres always petrol to get the products to the shops itself and then most people drive a car to the supermarket aswell so theres more co2 and were all thinking why isnt the world already DEAD!!!

So i think gm foods should not be manufactured because of the main reasons up there and because of a lot more that ive found in doing this project

why are gm foods grown

gm foods are grown for financial gain as these crops are mass produced and as they have genes that protect it from harmful diseases, these crops are then sold in shops for a price.

Also it is used to keep up with the growing population as these crops are mass produced the sheer amount of these can mean that there will always be vegtables,fruit ect.

these foods are sometimes enriched with certain vitamins and minerals so they can be better for you.

these crops are also mass protected so they are protected against pests.

advantages and disadvantages of gm foods

right well....
advantages of GM foods are
they cope better with unnormal condtions or conditions that are unsuitable
produce more crops and a better yield
gm foods use less fertilisers and also less water
they have a better pest resistance
better herbicide tolerance
provides more food which in return feeds the growing population



disadvantages of gm foods are
there harmful to the enviroment
harmful to humans
make numbers of superweeds rise
these superweeds then take over fields and crops
genes from the gm foods may get onto pests they then are immune to the pesticides which means that strongers ones are needed which maybe really harmful

with all of these good points it seems that GM foods are the way forward but with all these bad points is it really worth the hassle?
