ASK MR. GREEN: Organic Produce versus Nonorganic Produce
Dear Mr. Green:
Lately I see more and more "organic" fruits and vegetables in the supermarkets. I'm confused. Often the organic apples or strawberries aren't as red or as large as the other ones. They sometimes have
spots or insect holes. And organic produce can cost three times as much as other produce! So, tell me, what exactly are organic fruits and vegetables? And why are they so expensive?
Confused Shopper
Now Read Mr. Green's answer.
Dear Confused Shopper,
You're right. Sometimes organic produce doesn't look as nice as nonorganic produce, and it generally costs up to 50 percent more. Let me explain why.
Since about 1950, farmers have used chemicals to grow their fruits and vegetables. They use pesticides to kill insects that eat their plants. They use herbicides to kill the weeds that kill their plants. These
chemicals are a great help to farmers. By using them, farmers can grow more produce on…
Okay, maybe GMOs have decent uses but
it can't all be good. I've heard all of the
following about GMOs. Which ones are
realistic concerns?
select all that applys
a)Some GMO are patented and farmers must buy seeds every year rather than saving them from their crops.
b)GMO's cause allergies at a greater rate than crops produced by cross-breeding.
c)Inserted genes produce amino acids not found in nature.
d)Inserted genes may escape into wild plants near farmed fields.
Explain the a) social, b) economic, and c) environmental impacts of GMOs with one example each.

- Unlike genetically modified organisms (GMOs), synthetic organic substances have not met too much opposition, although the production of both require human intervention and manipulation of natural substances. Why do you think the synthesizing of organic substances is readily accepted by society in general whereas the mention of GMOs immediately raises concerns?arrow_forwardIn October 2002, the government of the African nation of Zambia announced that it was refusing to distribute 15,000 tons of corn donated by the United States, enough corn to feed 2.5 million Zambians for three weeks. The government rejected the corn because it was likely to contain genetically modified kernels. The government made the decision after its scientific advisers concluded that the studies of the health risks posed by GM crops “are inconclusive.” Do you agree with Zambia’s decision to turn away the corn? Why or why not? In your answer, consider that at the time, Zambia was facing food shortages, and 35,000 Zambians were expected to starve to death over the next six months. How do the risks posed by GM crops compare to the risk of starvation?arrow_forwardHow is the creation of GMOs different from naturally occurring life?arrow_forward
