reasons also take measures to avoid contributing to the
suffering and death of animals (and even insects) in other
capacities. For instance, a number of vegetarians refuse to
wear leather and silk because they see it as an ethical
violation of their respect for all living things.
Vegetarians who refuse to wear silk argue that the process
involves unnecessary cruelty to moth larvae. Rather than
allowing the moth to grow and leave the cocoon, silk
manufacturers boil the larvae alive, causing them to suffer
and writhe, in order to obtain longer strands of silk.
