Bill Maher talked to Canadian actress Ellen Page on Real Time about her work on the vanishing of the bees and their importance to our very survival and our ability to feed ourselves. Maher quoted Einstein during the segment who said this:

If the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees, no more pollination, no more plants, no more animals, no more man.
