Eijiro Myiako, a researcher at Japan's National Institute of Advanced Industrial Science and Technology, thinks there may be a technological fix. He and his colleagues have developed an insect-sized drone capable of artificially pollinating flowering plants.
Recently, Miyako's team loosed the tiny quad-copter on a wild lily. When it bumped into the male part of the flower, it picked up pollen — the plant's genetic material — and then transferred that pollen to the female part of another flower.
One problem is that there are more than 20,000 species of bees in the world, each of which has evolved to pollinate a particular plant or plants. Bumble bees are great at pollinating tomatoes. Honeybees are great pollinators for blueberries. And alfalfa leafcutter bees are great pollinators for, well, alfalfa.
"The idea that we can mechanize that is not really likely," Grozinger says. Even given plenty of time to fully develop a technological fix for the loss of bees, she doesn't think drones or another bee substitute would be capable of pollinating most plants. Nature is simply too complicated. "Nor should we want to," she says. "If we really do get rid of the pollinators then that means that our whole ecosystem is probably in trouble."
Taro Nakamura develops robots based on imaginative imitation of living organisms. His expertise is in great demand from numerous firms and government funded research programs thirsty for innovation, and he currently has over 20 individual projects in progress. We focus on his development of an earthworm robot, the first of its kind, designed to traverse the narrow, twisting tunnels of Japan's aging water infrastructure, and other projects including robots with man-made muscle fibers.
It makes me sad that our bee populations are dwindling and the scientists still can't agree on what's causing it. While the drone idea is a nice one, I don't think it'll be possible to completely replace bees. We'd have a global disaster if bees went extinct. Many species would follow if that happened. It's actually scarier than climate change.
