Bees are under threat worldwide from disease, pesticide and habitat loss- this is a serious problem for biodiversity and food security in the medium term.
For a comprehensive overview, look at the UNEP report: Global Bee Colony Disorders and Other Threats to Insect Pollinators.
It highlights for example that of the 100 crop species providing 90 per cent of the world’s food, bees pollinate more than 70 per cent.
What would we do without them??
In economic terms, pollinator services contribute around US$200 billion a year to the global economy.
