Theoretically, the food we produced worldwide could sustain all the current population both in quantity and energy in calories if look through a nutrition perspective. However, food security remains the top most crisis for all human beings. If we calculate greenhouse gas emission for all food waste on earth, it ranks number 3 just after China and the US. I believe there is a sustainable way of farming and agriculture that could sustain all people in the world with a diversified food types.
I envision that large agribusiness corporations and environmental organizations recognize the power of diverse, perennial, polycultures as we saw in the biggest little farm. The power of ecosystem resilience and the harmonious of species coexistence achieved from biological integrations are far more effective and sustainable than chemical pesticides.
To achieve this, fundamental institutional and political changes should absolutely take place. Government should redistribute the subsidies for producing profitable crops that feed the livestock to staple foods that sustain people’s life. The profit bond between politic, business and the environmental organizations should be weaken, even though I have not think about a way to break this. These influential parties should not deliberately overlook the environmental problems and destructions caused by agriculture and livestock. It is time for campaign and appealing for reducing meat consumption and build a real sustainable farming and food production.
