Can emerald ash borers kill humans?
The spread of the emerald ash borer, which poses no direct threat to humans but has killed more than 100 million trees in the United States, was associated with an additional 15,000 human deaths from cardiovascular disease and an additional 6,000 deaths from lower respiratory disease.
What are some negative effects of the emerald ash borer?
Emerald ash borer infestations cause significant ecological and economic impacts in forested and urban habitats. In forest habitats, losing the majority of ash trees can affect tree species composition, natural forest succession, and nutrient cycling. Habitats also become more vulnerable to invasion by exotic plants.
How does the emerald ash borer affect the food chain?
Emerald ash borers do their damage as larvae, eating into the bark and burrowing deep into the trunk to insulate themselves against the cold. In the process, they cut off access to the nutrients and water that the tree needs to survive; it is like severing a humans network of veins and arteries.
