Abstract
Many substances described in this section involve the use of living creatures and although the materials produced are undeniably attractive, the interests of conservation should be put first; it is far more important to ensure the continuation of a species rather than to use it for merely ornamental purposes. Some recovery techniques are cruel and it is to be hoped that the practices will eventually cease.
