Some take the position that there are essential (food, medical research) and non-essential (entertainment) uses

Livestock producers support proper feeding, housing, vet care and good management practices because these result in greater productivity.

Views vary. Some advocate the total elimination of all animal

use by humans. Others focus on eliminating animal suffering to

the greatest extent possible. Those who take a moderate approach try to

achieve their goals by influencing legislation and through public education campaigns.
