McKenzie is a bee keeper who worked on protecting the bees since 2006 and this has helped him to look after an apiary in the White House grounds."Bees play a major role in our ecosystem. About a third of the foods we eat are pollinated by bees," says McKenzie."They pollinate the trees to produce fruits which feeds birds, which feeds humans. Without the bees, many organisms wouldn?t have the ability to procreate."Bees have been dying because of lack of habitat, pesticides, herbicides and a problem known as colony collapse disorder.
