food source maps

maps comparing food sources, vegan would use small local gardening, in vegan winter areas canning and a larger seasonal area is used

factory farmed animals would have arrows from huge swaths of corn to animals to slaughterhouses to cities, grass fed animals arrows would be short in a few areas

unused areas would provide ecosystem services,

smaller arrows for light transport, larger arrows for polluting transport

show current arrow map for a city, compared to the map for the same city with vegan sourcing
