The promise of finding
long term technological solutions to the problem of world food shortage seems
difficult to fulfill. Many innovations that were once heavily supported and
publicized, such as fish protein concentrate and protein from algae grown on
petroleum substrates, have since fallen by the wayside. The proposals themselves
were technically feasible but they proved to be economically unviable and to
yield food products culturally unacceptable to their consumers.
One characteristic common to unsuccessful innovations has been that, even
with extensive government support, they often have not been technologically
adapted or culturally acceptable to the people for whom they had been developed.
A successful new technology, therefore, must fit the entire social cultural
system in which it is to find a place. Security of crop yield, practicality of
storage, and costs are much more significant than had previo A. a suggestion is made and arguments in its favor are provided. B. a criticism is imposed and an alternative proposal is suggested. C. a generalization is advanced and supporting evidence is provided. D. an example is analyzed and general conclusions are derived from it.
