Can you imagine a world without bees? The book by the same name....A World Without Bees describes a grim scenario.

In the US, honeybees are trucked across the country to provide pollination services to huge farms of one crop (California’s almond plantations being the largest) after another – spending long days on the road and never having a chance for a holiday. The increased industrialization of agriculture and urbanization means that bees diets are becoming more limited, and they are suffering nutritional stress. And we’re adding GM pollen to their diets.
Climate change is affecting bees too, with different flowering times for plant species and changing weather conditions that affect foraging bees.
What this adds up to is a complex mixture of industrialization, urbanization and globalization effects that bees simply may not be able to cope with. If honeybees die out, vast areas of agricultural land will go unpollinated – and the world will starve.
