2. 70% of European plants are accostumed to insect pollination.
>genetic conformism in plantsYou don't have any fucking idea of what are you talking about, bees can travel 10-20 km from their honeycomb turning them in one of the main insects that prevents genetic drift and genetic homogeneity in plants.
Pro tip: the term "genetic conformism" does not exist and I can spot anyone who didn't worked in the Ecology field before because the misusing of wrong concepts.
>>5038407They are insect superpredators but they cause population decline in bees, it's difficult to hunt and eat a wasp or a hornet so there are no bird species that can predate wasps [at least in Europe]. Wasp extermination can be even better for the environment much like the extermination of some species of mosquitoes that can carry viruses/bacterias/parasites.
