A farmer has decided to switch from the current way of raising livestock to a more sustainable way. Which of the following best describes the type of environmental change that the livestock will experience?
Answer
A
The livestock currently live in barns, and they will be hand-fed grain to make their lifestyle more sustainable.
B
The livestock currently live in barns, and they will be let into an open range to make their lifestyle more sustainable.
C
The livestock currently live in a field, and they will be put into barns in order to make their lifestyle more sustainable.
D
The livestock currently live in a field, and they will be hand-fed grain to make their lifestyle more sustainable.
Explanation
A more sustainable livestock system typically allows animals to graze outdoors rather than keeping them confined in barns. Moving livestock from barns to an open range changes their environment in that direction. Hand-feeding grain or moving animals into barns would not describe this change.
