Moreover, the article entirely ignores wild bees. That's somewhat understandable as they're not as well studied, but they're a significant pollination force nevertheless -- according to this White House fact sheet [1], wild bees accounted for $9 billion of the economic benefit of pollination (compared to $15 billion for domesticated bees). The wild bees are not being replaced. This article really does have a lot of dodgy accounting (esp ignoring externalized costs).
Shamelessly plugging a related project, I recently contributed to a game [1] designed to illustrate that wild bee populations have economic value. Jana Vamosi, a biologist from the University of Calgary, submitted the project idea to the Mozilla Science Lab [2] to get help building it. There's a lot of room for improvement, actually, if anyone wants to lend a hand.
I find it incredibly sad that the only way to make people care about the destruction of wild bees is to talk about how much economic benefit they provide.
