The health of our babies depends on the health of bats
When you think about ways to improve the health of human babies, you may not immediately think of helping bats stay healthy. You should. The journal Science published a shocking paper linking a rise in human infant mortality to a declining bat population.
In addition to being pollinators that bring us the gifts of flowers and food, bats also consume massive amounts of insects that would otherwise infest our crops and cause us endless hours of itching from bug bites. A single bat can eat up to 1,200 mosquito-sized insects every hour, and each bat usually eats 6,000 to 8,000 insects each night. That’s a helpful service but what does that have to do with infant mortality? It’s a direct cause and effect.
Plagued by an outbreak of the deadly white-nose syndrome, a fungal disease that kills bats, North American bat populations are dropping. This means there are fewer bats to eat insects that infest crops. That’s caused farmers to use more chemical insecticide. This insecticide leaches into crops, land, and water. This toxin has increased infant mortality. It’s also lowered crop yields, decreasing farmers’ crop revenue and the availability of fresh fruits and vegetables.
This is just the latest study to show how the health of ecosystems is directly linked to human health and the economy. As much as I’d love for municipalities and companies to care about the planet because we depend on nature for our survival, as climate communicators and nature advocates we often have to make the economic business case to protect the environment. Studies like the one in Science linking bats and infant mortality provide a solid example of how to quantify the cost and value of biodiversity and ecosystem health.
I often hear the media vilify animals like bats without recognizing the vital role they play in our lives and in nature. If we can’t get people to care about bats because they are sentient beings and a part of nature, maybe now we can get people to care about them because they affect babies, the food supply, and our economy. If that’s the argument that works, it’s the argument I’ll make, backed up with research-based science and facts.
Protect babies. Protect bats.
