Summary
US honeybee deaths hit a record high, with beekeepers losing over 60% of colonies this winter.
The crisis threatens pollination of key crops and has led to financial ruin for many beekeepers. Scientists cite climate change, habitat loss, pesticide use, varroa mites, and poor handling as potential causes.
The USDA is investigating the latest losses, but Trump-era staff cuts have slowed research, prompting Cornell University to assist.
Despite increased colony numbers from rising beekeeper interest, loss rates continue to surge, endangering agriculture and ecosystems.
I’m guessing pesticide usage is probably killing a lot more bugs than we realize. Bees are one of a number of pollinators. Wasps, moths, bats, hummingbirds, and other creatures also play a role.
Between destruction of habitat, overuse of pesticides, and climate change making things hotter/drier/easier for diseases to spread, I think those are probably the main factors.
