Answer 1

well its fair and unfair too as it provides us with wools and many other valuable things and unfair as its not good its a type of torture to animals

By cutting their hairs we are bot harming them.. but if you see that human uses every thing which is beneficial to them so they shed off their hairs for different purposes and seriously it doesn't affect those animals at all.
