Insect fatalities at wind turbines as biodiversity sinks

How does this compare with the number of insects killed by cars on the highway?

It seems foolish to focus research on wind turbines when cars kill many orders of magnitude more. Why not research how to reduce car-insect-fatalities?

Because the fossil fuel industry won’t fund it? Cars are financially beneficial for them.

The article says it has no conflicts of interest, but I’m very skeptical.

If the problem is insects flying against the turbine mast I wonder how many insects are ‘killed’ by a tree every year.

They mention insect detritus impacting laminar airflow, so the collisions are at the blades.

"…40 million insects killed annually by a single wind turbine in Germany…" That's about 13 tons of biomass per blade, three times the weight of the blade itself. Why aren't they covered in black muck?

Up close, turbines generate lots of noise, unnatural air currents, and EM field. Seems like an ideal situation for natural selection.
