A secure food supply depends on all of the following EXCEPT?
Choose one answer.
a. maintaing healthy soil and water
b. increased use of fertilizer
c. safe distribution of food
d. biodiversity
So I'm guessing that's the complete question you're looking to have answered (found it on Google), and my best guess would be C. Since normal soil should be enough to grow food, increasing the amount of fertilizer used could cause the soil to be infertile. Hope that was what you're looking for!
