GGR227H5 Lecture Notes - Lecture 6: Burrowing Owl, Organic Farming, Biocide
Document Summary
The green revolution: start of modern agriculture and modern agricultural practices, higher yield seeds more output per seed, produce more per unit, reliance on auxiliary energy flows much greater use of natural resources, increase in the use of technology and big machinery, hybridization crossbreeding of two varieties or species and animals, select for certain traits, decrease genetic variation, genetically modified organisms (gmos) organisms that arise from the combination of genes from different and often unrelated species. But it is not economically viable: derivations from plants and other organic material, advantages of biofuel, generates a fraction of the pollutants that petroleum based fuels produce, has the potential to reduce foreign oil dependency, lower fuel prices, increase income for farmers easy to produce, provide new jobs creation, production, disadvantages of biofuel, large amounts of inputs: fertilizers, pesticides, machinery, processing, large amounts of energy used to do so, land is taken away from food production!
