And trees need bees!
Oh, and they’re great for the economy, too.
In 2010, it was estimated that they contribute $40 billion per annum. According to the American Beekeeping Federation, honey bees add $15 billion to US crop alone.
As concluded by the Earthwatch Institute at the last meeting of the Royal Geographical Society of London, they have been placed at the top of the list of the most powerful living things on the planet.
