Which of the situations below describes an ethical dilemma related to food engineering?

a. preservatives are used so that food can reach consumers before it spoils.
b. organic compost is used in the fall to fertilize the ground so plants will produce more.
c. local libraries host garden experts who educate consumers about which produce grows best in the area.
d. one pesticide is used to protect a crop from being destroyed, but studies have linked it to thyroid disorders.

I think we have to look for a dilemma here: so something that has both a positive and a negative effect.

in options a) and b) we see only positive effects; agriculture being more efficient. option c) just describes an activity related to food production, but not food production itself.

The best answer is D.One pesticide is used to protect a crop from being destroyed, but studies have linked it to thyroid disorders.  - the dilemma is between the crop being destroyed and thyroid problems
