- agriculture is worldwide the biggest consumer of water (13,000 liters of water are needed to produce one kilogram of meat)
- agriculture is worldwide the biggest polluter of water (insecticides, pesticides, fertilizers seeping into rivers and ground water)
- agriculture is worldwide the biggest cause for soil degradation and soil loss (removal of nutrients, erosion, salination of soil, deforestation for new agricultural plots)
- agriculture is a massive energy consumer (for every 1 calorie of food produced 9 calories of energy are put into the agricultural system, most products (fertilizers, pesticides, insecticides) come from the petrochemical industry, i.e. are derived from oil)
- agriculture reduces food diversity (75% of plant food seed species have been driven to extinction in the last 60 years, more than half of all food plants grown today are from only 4 species: rice, wheat, soy and corn)
Bill Mollison once said: our current agriculture is not a system to produce food, it is a system to produce profits. Let me add to that: "... it is a system to produce profits at any cost, including sick people, sick water and a sick land."
