Imagine if bees could stop humans from killing them by hijacking pesticide sprinklers, putting up banners and picketing grocery stores. That would be the bee's knees.
According to Greenpeace's related website, sos-bees.org, "Bees and other pollinating insects play an essential role in ecosystems. A third of all our food depends on their pollination. A world without pollinators would be devastating for food production."
All they are saying is it's really gonna sting unless we "give bees a chance."
