Golf courses now that makes more sense... they are growing a crop of grass for looks... not to harvest,
Golf courses are super rare in this area, so you can't blame a majority of the phosphates on golf courses.
And no I don't want to stop food production, I just want to encourage more environmentally sustainable methods of food production.
For example due to the water shortage in California they developed methods of targeted watering. That hasn't come to Florida because $175 gets you all the water you want for a year. Start metering water usage and charging by use for all commercial accounts. It doesn't need to very high, in fact start it very very low and ramp it up slowly to get the desired balance.
I think we need better planning for fertilizer application for all forms of commercial usages, plans to deal with run offs from livestock, etc.
I don't want to turn Florida into California, but I also don't want to destroy the fragile ecosystems of the Florida springs. We have to find a balance that works for everyone.
Though this problem might be solved in the future as farm fields are turned into cookie cutter communities or solar panels. But then we have a different problem, too many yankees.
