The forth opportunity could be production of feed
ingredients from non-food sources such as wood fibres, plant fibres and sea
weed. To get to the sugars they in large are composed of it is necessary with
tough treatments such as hydrolysis, high temperatures or pressures, but the
result may be highly valuable. An research are giving directions for
possibilities.

The fifth effort lies in the use of bacteria, fungi and
moulds as production units for fat, carbohydrate and protein. They are
excellent transformers of unwanted and abundant resources into high grade raw
materials for food and feed. Dairy industry utilise this with great
sophistication today, but GM technologies may accelerate this enormously.

The sixth opportunity is the discard of fish at sea. Today
quotas are calculated, based on how much is landed. Therefore much is discarded
at sea and never landed. Only in the EU this amounts to several million tonnes
in the years before the ban is being implemented (5-15 million tonnes of fish).
This is raw materials good enough for food, but rather than throwing it back in
to the sea this would also make feed for a similar amount of high value fish
from farms (40 % of the feed formulae).
The last effort I would have liked to see a joint
international focus on is vertical production of fruits, berries and
vegetables. This diverts the pressure from intensive land use over to
production that could be done inside cities if necessary. This will release the
pressure on fuels for transportation and cut future waste.
To double or triple the food production should be a piece
of cake, the bigger question is do we want to?
The economic interests in maintaining high raw material
prices are probably stronger. My argument against this static view is that
these radical scenarios would most likely unlock the economic crisis and
generate new growth in a better world of tomorrow.
The way out of a depression has in earlier times always
been to generate a new market. Food must be the perfect vehicle for this, but
the customers still lack in buying power, and this is an ethical and political question
and should not be up to the market forces uncorrected.
