>> Seems like insecticides, but we really don't know! Has insecticide use really increased that much since the 80s across the west?
The amount of insecticides used doesn't need to increase, to cause a mass extinction. A constant dose is enough, if it kills more insects in a given period, than are born in the same period. Over time, this will cause the number of insects to decrease steadily.
