Genetically Modified Organisms (GMOs) are used in the production of many medicines and foods?
I have heard that. Which types?
A majority of the food modifications come from traditional cash crops such as cotton, corn, soybean and canola
Yeah, I remember reading about soybean crops that were Genetically modified. I heard that they were bad for you.
A key point of contention involves the effect of pesticide resistance and its impact on the crop
Yes, I heard other farmers complained that their cops were getting cross pollinated. 
Cross pollination creates new seeds with modified genetic makeups. This is useful for creating crops with desired attributes
Yes, but then when they cross pollinated the farmers were sued for keeping seed from the new seed.
This reminds me of a 2004 Supreme Court case between a farmer and biotech company
Yes, I believe that is the one I remember. I think the company won though.
