I have 4 acres. Lawn. About 3 sq feet.
The "red tides" aka super algae blooms in Florida's oceans, estuaries, and waterways are caused and/or worsened by fertilizer. Growing food crops takes less fertilizer than a lawn. I have green weeds, from a distance it looks like grass. I refuse to let the HOA put anything on it as I am less than a mile (about 1 km) from an estuary that is unique in the world as it is where temperate and subtropical meet, fertilizer affects the sea grasses that manatees and other species depend on.
When I had my farm the solution for mowing was to let my 3 acre front lawn grow into a meadow. It only took one summer for the whole thing to turn into a great variety of flowers. In the autumn I would mow it and rake it. That would spread the seeds for next summer. The collected refuse would go onto the compost pile (behind pole in photo).
