Can we afford to lose bats? A recent study by Eyal Frank of the University of Chicago reveals that the dramatic decline in U.S. bat populations due to white-nose syndrome (WNS) has led to significant economic and health consequences.
Key Findings:
- Increased Pesticide Use: With bats serving as natural pest controllers, their decline forced farmers to increase chemical pesticide use by approximately 31%.
- Rise in Infant Mortality: The heightened pesticide usage correlates with a 7.9% increase in infant mortality rates in affected counties, amounting to an estimated 1,334 additional infant deaths between 2006 and 2017.
- Economic Impact: Farmers experienced nearly a 29% drop in crop revenue, and combined with health-related costs, the total societal loss is estimated at $39.3 billion.
Conclusion:
This study underscores the critical role bats play in agriculture and public health. Their decline not only disrupts ecosystems but also imposes substantial economic and human health costs. Conservation efforts to protect bat populations are not just about preserving biodiversity — they are essential investments in our economy and human health.
