And they greatly enhance the yield of crops, most of which are also not native to North or South America. And North American bee husbandry is greatly superior to that of Europe. And wasps, butterflies, flies, Beatles, do not make honey or wax, although you never know what George Harrison and Ringo Starr may get up to. Finally, if bees are dying for lack of water, so are wasps.
I don’t think George Harrison has been getting up to very much for the last 20 years or so.
“And wasps, butterflies, flies, Beatles, do not make honey or wax,”
Not making honey or wax is a far cry from ‘There would be no life if the bees die’ as your title says. If not having honey or wax is such a crisis how did life survive in North and South American before their arrival? Apparently, just fine.
“Finally, if bees are dying for lack of water, so are wasps.”
If lack of water is killing the bees then how are the people of Brazil still alive? Don’t they need more water than insects?
