As regards pollination, for
instance, scientists have estimated that if we had to do by hand what is
currently done for us for free by bees, bugs, birds and bats, the annual cost
would be well in excess of half a trillion dollars. Sounds crazy, doesn’t it?
But in the province of Szechuan in China, that’s exactly what they’re having
to do right now. Having wiped out most of their benefi cial insects through
the over-application of pesticides, they’re now having to collect pollen by
hand and apply it (using feather-dusters!) by hand to keep alive their
hugely valuable orchards.

The collapse of the bee stock in Szechuan is as a result of CCD. Not something that has, at least as far as I know, been definitively linked to pesticide use.

But hand pollination? Isn\’t this a normal, or at least often used, technique in fruit orchards anyway? There are references here to studies of it in the Pacific North West in the 1940s.

  1. But surely he should welcome the creation of all those pollinator jobs? Or is he finally getting the jobs as cost argument……?

  2. The lack of bees is depending of the use of pesticids. No beekeeper want to move bees into the area because they use pestcids also in bloming crops.
    It has nothing to do with CCD.
    Se 7 : page 14
    ” All the informants mentioned that it was pesticides/insecticides that have killed most insects if there were any insects and that have driven the honeybees out of the pear cultivation area. Use of insecticides is regardedas the sole reason for no insects pollinating pear flowers and for no beekeeping in the region.”
