Bat Decline Linked to Rise in Infant Mortality

A deadly fungal disease, white-nose syndrome (WNS), has decimated bat populations across North America since 2006, leading to significant ecological and economic impacts. Bats, which act as natural pest controllers, have seen their numbers decline drastically due to WNS, causing farmers to increase insecticide use by 31% to compensate for the loss of these predators. This increased pesticide usage has been linked to a rise in infant mortality by 8%, equating to over 1,300 additional infant deaths, as documented in a new study by environmental economist Eyal Frank. The study highlights the broader consequences of biodiversity loss on human health, emphasizing the interconnectedness of ecosystems and human wellbeing. Researchers have stressed the importance of preserving species like bats to maintain ecological balance and protect human health.
