What states in US grow genetically modified crops?
Virtually every state in the US except Alaska grows at least some GM crops, glyphosate resistant being the most common trait used.
What are benefits of gmos product?
One benefit of GMO production was said to be that less herbicides would be used on them. This; however, has not proved to be the case after they were used for several years. After years of using them, it appears that the use of glyphosate has doubled due to the use of glyphosate resistant crops.

What are the Main genetically modified crops in United States?
The main ones are corn, soybeans, and cotton. They all have varieties which are resistant to glyphosate (Roundup is one trade name), and corn and cotton have some insect resistance (Bt traits) as well.
What is harmful about genetically modified foods?
Some say GMO foods are not harmful. Others say they are harmful. Still others, who are probably right, say it is not known whether they are harmful, though we do know that the FDA has doubled what is considered the acceptable level of glyphosate in foods (the herbicide used on a large percentage of GM crops), glyphosate is harmful to the soil, crops that are resistant to other synthetic pesticides have been developed, many people who choose to eat non-GMO diets at the advise of their doctors have improved health, etc.
Why are crop plants that are resistant to glyphosate so significant to farmers?
Glyphosate is a broad spectrum herbicide. Normally this would kill the crops too, but glyphosate resistance allows farmers to control weeds extremely effectively, increasing yields, reducing costs, time, and allowing conservation practices such as no-till or conservation tillage farming.
What is one of the problems with improving the food supply by genetically engineering better crops?
Some crops are genetically engineered to resist certain herbicides, which means the herbicides they are engineered to be resistant to can withstand having the herbicide sprayed directly on the crop. A known problem with these crops is that after a number of years, more herbicide is needed to control weeds. Because of this, more herbicides are sprayed on the crops and end up in foods. The safe limit for glyphosate (Round-up) in foods has been raised by the EPA in the United States and the use of Glyposate on crops has doubled in the years since Glyphosate resistant crops have been commercially grown. Other crops are genetically engineered to produce an insecticide in the plant itself. Though the insecticide is suppose to target certain insects, two concerns are that non-targeted insects are being killed and people's and animal's health may be affected when those crops are eaten. Generally, some believe horizontal transfer of the engineered genes in the crops may occur. Another problem that has occurred is weeds have developed resistance to the herbicides crops have been engineered to resist. The absence of long-term studies concerns others, making some feel that they are the long-term study.
Why would GM crops need less pesticides?
GM crops having disease resistant genes hence they are resistant to disease and pests so they not need more use of pesticide.
Is glyphosate organic?
It is in chemical sense an organic molecule. Glyphosate can only be originated by organic synthesis by the human. Otherwise, glyphosate is not present in nature.
What is another meaning for glyphosate?
Glyphosate is the active ingredient in Roundup® brand herbicide.
What did people not do in response to the environmental limitations on farming?
Develop drought-resistant crops
