A future without bees - a podcast by BBC World Service

Tech companies have developed drones to drop pollen on orchards or shoot it at crops through pipes from tractors.

They’re responding to a crisis in insect pollination as studies suggest numbers of both wild pollinators and farmed bees are declining. This could have a serious knock-on effect on how we grow our fruit and veg. But some experts argue high-tech alternatives are a short-term solution to a much bigger and long-term problem.Presented and produced by Claire Bates
