80%
Industrial agriculture produces 80% of the world’s food
Most land
Wheat
World food crisis 2007-2008
Lowest reserve level thus prices rose:
Corn doubled price
Wheat and rice 150%
Developing countries
Growing population results in higher meat consumption, grain consumption and fossil fuel use
Prices
Prices for food are volatile while production is stable due to pressure on farmers to keep up
Wool
Declining in demand and production
% of fibres
Synthetics are taking over the market due to cheaper to produce price
International reliability
International reliability becoming increasingly important due to globalisation
Agribusinesses
Diversifying into multiple country corporations
