OSLO (Reuters) - Pesticides used in farming are also killing worker bumblebees and damaging their ability to gather food, meaning colonies that are vital for plant pollination are more likely to fail when they are used, a study showed on Sunday.
The United Nations has estimated that a third of all plant-based foods eaten by people depend on bee pollination and scientists have been baffled by plummeting numbers of bees, mainly in North America and Europe, in recent years.
