Why would cost us £1.8bn to do what the bees do for free?
Imagine a world without bees. Someone would have to pollinate all the crops that we depend on for our food -- and to do it ourselves could cost £1.8 billion a year. It's a huge sum, and it's been calculated by scientists at Reading university at the request of the environmental campaign group Friends of the Earth, who launched a campaign today on behalf of our rapidly dwindling bee population. Stuart Roberts is a research fellow at the Centre for Agri-Environmental Research at Reading university, so I asked him: how on earth did they come up with that figure of £1.8 billion?
