Welfare Considerations

Mass depopulation represents an extreme welfare event causing deaths of millions of animals under time pressure that can compromise humaneness. Investing in humane depopulation method development, planning, and regulation is essential even though these situations are exceptional, because the welfare impact when they occur is enormous.
