To lobby the Government to do more and provide funds for research into Colony Collapse Disorder and why the number of honey bees are declining in the UK.

 

 

Bees are dying in their Millions - what do we do?

Bees are dying in their millions. Martha Kearney, BBC 4, explores this worrying phenomenon.

It is an ecological crisis that threatens to bring global agriculture to a standstill. Introduced by Martha Kearney, this documentary explores the reasons behind the decline of bee colonies across the globe, investigating what might be at the root of this devastation. Honey bees are the number one insect pollinator on the planet, responsible for the production of over 90 crops. Apples, berries, cucumbers, nuts, cabbages and even cotton will struggle to be produced if bee colonies continue to decline at the current rate. Empty hives have been reported from as far afield as Taipei and Tennessee.

In England, the matter has caused beekeepers to march on parliament to call on the government to fund research into what they say is potentially a bigger threat to humanity than the current financial crisis. Investigating the problem from a global perspective, the programme makers travel from the farm belt of California to the flatlands of East Anglia to the outback of Australia. They talk to the beekeepers whose livelihoods are threatened by colony collapse disorder, the scientists entrusted with solving the problem, and the Australian beekeepers who are making a fortune replacing the planet's dying bees. They also look at some of the possible reasons for the declining numbers - is it down to a bee plague, pesticides, malnutrition, or is the answer something even more frightening?

Go to BBC4 Bees are Dying in their Millions to watch this interesting and worrying documentary.

In a contrasting documentary, by the same author, Orlando Clark is an urban beekeeper, he keeps his bees in various locations around the city of London, from Brixton to King's Cross. His bee losses have been no higher in the last few years than they have been in any winter. In fact, last winter was better than ever before. Ironically in the city, there seems to be more and cleaner food for the bees to eat. London and a lot of urban environments are actually quite green, with an abundance of parks and gardens dotted all around. The diversity of the plants you have in the urban environment may help the bees, as there is almost always something in bloom all year round. In the countryside, particularly with modern agricultural practices, you have whole swathes of land supporting just one crop, which may bloom for only 2-3 weeks. The city is probably one of the best locations to keep bees at the moment, as there is plenty of forage for them and they don't have all the problems they have in the countryside with insecticide and pesticides being sprayed on them and their food.
