Apex Scavengers Have a Purpose

People often react with disgust when they see videos of hyenas eating decaying remains of a dead cow or deer. Vultures have long been viewed negatively because people associate them with feeding on the carcasses of dead animals. However, these apex scavengers have a purpose in the natural world. They help control diseases that could otherwise spread uncontrollably.

The list of diseases that apex scavengers help prevent is extensive. Diseases like anthrax, botulism, salmonella, E. coli, and rabies are just some of the illnesses that could be avoided if healthy populations of apex scavengers were maintained. Between 1992 and 2006, the use of a veterinary drug caused India’s vulture populations to crash. This led to an increase in feral dogs consuming carrion, resulting in over 48,000 rabies deaths from dog bites.

Humans generally see apex scavengers as evil and have often destroyed them. The Red List of Threatened Species, published by the International Union for Conservation of Nature, states that 36% of apex scavengers are threatened or declining. Without their presence, smaller scavengers like rats thrive and spread zoonotic diseases that apex scavengers could help prevent.

Millions of people die each year from zoonotic diseases, and that number will rise if apex scavengers are eliminated. God created everything for a reason, and apex scavengers have a purpose. Their intentional destruction of scavengers (and predators) is a classic example of how human ignorance has caused human misery. When we look at the problems facing humanity today, many stem from the violation and misuse of the good things God created.
