We can, especially if we have gardens, help Honeybees and British Wild bees by:
Bees are worth £26 billion to the global economy, and £200 million in Britain.
Bees contribute to global food security and their extinction would represent a terrible
biological disaster,' said Bernard Vallat of the World Organisation for Animal Health.
The British government denies the existence of Honeybee Colony Collapse Disorder (CDD) in Britain, blaming rainy summers that have stopped bees foraging for food.
We worry about global warming, but unless China, India, Brazil and the USA, get genuinely proactive in doing something about it, whatever we do, including messing up our countryside with wind turbines, covering our roofs with ugly taxpayer subsidised solar panels and other Liberal renewable energy initiatives that only increase our energy bills, we can't do much about it.
