During World War II, the government encouraged citizens to replace lawns with Victory Gardens.
Replacing or reducing lawn size in favor of Victory Gardens allows more people to control the foods they eat.
We have to overcome the common mindset, and local ordinances, the suburban homes need to have manicured lawns.
We should encourage a new conventional wisdom that lawns are not productive or environmental friendly. Permaculture principles reduce the need for chemical applications and excessive water use and create a environmentally friendly food forest that supports humans and wildlife.
