Depleting The Gene BankStreaming Video - 2008
This program discusses the dangers of selecting and breeding better and better and fewer and fewer varieties. It explains the dangers of depleting the gene bank: when new diseases or predators appear, entire species may be wiped out because no naturally-resistant varieties remain; and the smaller number of varieties offered tend to omit the regionally well-adapted ones in favor of more generally adapted plants-another disaster waiting to happen. The hopeful side of agricultural experimentation is plant tissue culture, which is the model for an entirely new way to produce more and better plants, more quickly. The reality is that in agriculture, no fix is permanent-insect genetics are constantly changing, and agricultural geneticists are in a race against world starvation.
