Driving something around on a truck does not necessarily translate into a
big relative expenditure of energy, particularily if the payload will
result in a considerable increase in yield. It presently takes 7.3 energy
units of non-renewble energy to make 1 energy unit of food in the US (the
entire system takes 10.2 Quads to produce 1.4 Quads of food energy). If
someone were to do the calculations, from strictly an energetic
standpoint, moving bees and, thus increasing yield, might make sense and
ultimately reduce the 7.3 state-of-affair. Fertiliser application,
afterall, gobbles 40% of the US food energy use in food cultivation...
transportation is just a blip. If you can get the same yield by
decreasing fertiliser use and bumping up the bee density, then I think
bees could play a part in reducing overall energy use in agriculture. No
one knows this for sure: I only bring this counter arguement forward to
demonstrate that this assumption may not be a given. Allen previously
pointed out the possible pitfalls of this logic, his good example was
organic apple production where hand-thinning is the only way to deal with
over-abundant fruit set. These pitfalls, however, should encourage us to
look into the dynamics of this relationship rather than write the whole
area of study off at the outset.
I am not so foolish, and neither are any of you, to conflate
sustainability entirely with energetics. There are clearly more factors
that need to be considered when formulating sustainable agriculture than
just this one element (eg Ted presents the case of 500 vs the 5000). A lot
of these issues, however, are not as readily as calculated as energetics.
