The Dangers of Biodiversity Loss in Africa

Before the emergence of COVID19, there was a common misconception that the “era of infectious diseases” was history due to technological advances and the widespread use of antibiotics and vaccines. However, recent studies have pointed to the growing emergence of zoonotic pathogens, specifically in Africa. 

Key causes of new viral infections stem from areas with high population densities and frequent human interaction with wild animals. The food and agriculture system is increasingly impeding into wildlife, putting global health at risk. Rising populations in Africa are accelerating the expansion of agricultural lands and human settlements into wildlife, while simultaneously fueling the growing bushmeat market. Wet markets for these bushmeats are commonly found in Africa with limited regulations and/or resources leading to overexploitation, hunting and poaching.

Transmission of Wildlife Zoonotic Pathogens

Livestock farmers face severe pressure to meet the market demands and are highly vulnerable to potential infectious diseases. The most common emergence of pathogens from primates are known to come from bats. But, we are seeing more frequently that amplifier hosts, such as pigs and other livestock, are increasing the transmission rates to humans. With overall meat production being at an all time high, this is highly problematic.

Bushmeat has been hunted for centuries by communities who relied on it for subsistence. Bushmeat remains a vital source of food for many impoverished areas in Africa, so it is unrealistic to ban the consumption of these animals altogether. However, bushmeat is often used today to feed Africa’s wealthy urban population, shifting its original purpose of subsistence to a highly profitable commodity. 

To address the growing concern of zoonotic pathogens, there must be effective enforcement of hunting quotas. Cultural preference for the “exotic” bushmeat must also be shifted. Implementing educational programs linking bushmeat practices to zoonotic pathogens could be a start to reducing the number of wildlife animals hunted.
