About 1.4 billion jobs and three-quarters of all crops depend on pollinators, researchers said today warning of a dire threat to human welfare if the falls in bee and butterfly numbers are not halted.
Pollinators added some USD 235-577 billion (222-545 billion euros) to crop output per year, said the team."Agriculture employs 1.4 billion people, approximately one-third of the world's economically active labour force," said the review published in the journal Nature."This is particularly important to the world's poorest rural communities, 70 per cent of whom rely on agriculture as the main source of income and employment."Most pollinators are insects such as bees, butterflies, moths, wasps and beetles, but others include birds, bats and lizards while some crops are pollinated by wind.The team said crops which depend on animal pollinators are crucial for balanced human diets, providing micronutrients such as vitamins A and C, calcium, fluoride and folic acid."Pollinator losses could therefore result in a substantial rise in the global rate of preventable diseases," the researchers wrote."This could result in about 1.4 million additional deaths per year and approximately 29 million lost years of healthy life," the researchers wrote.Wild plants are also at risk -- more than 90 percent of tropical flowering plant species rely on animal pollination, said the team.Almost one in five vertebrate pollinators, mostly birds and bats, are threatened with extinction. And among bees -- the most numerous pollinators by far -- about nine percent were catalogued as threatened, with a similar percentage for butterflies.(This story has not been edited by NDTV staff and is auto-generated from a syndicated feed.)
