Conserving wildlife is not very different from improving public health. They both involve (sometimes nasty) debates between people with different opinions and values. In health, some most value the enjoyment they get from smoking or unprotected sex, while others value stopping the illnesses caused by these behaviours. In conservation, some value the management of predators above all else, while others value animal control that does not use poisons or is less cruel or they find value in the comfort of a pet cat.
