In my home state of Wisconsin, about 85% of the state was forested when Europeans showed up, but by 1915, only 1% of the state had forests. Farms, cities, selling wood, etc. Today, the state is back up to nearly 50% forests. It turns out that not all forested land was useful a farmland, and you can't harvest trees for wood if there are no trees left. Even St. Johns County will likely never decide to clear cut 99% of the forest. The main difference is that today's clear cutting is to build wide roads and mini malls next to sprawling neighborhoods with pretend beaches and other amenities, not farms or factories.
My family farmed Wisconsin land for 150 years, providing food and milk from about 100 acres. The land was mostly deforested, even if there were a couple of "woods" on the property. But if my cousin decides to plant trees instead of crops, the forest would come back. I'm sure most of St. Johns forested land had already been deemed deficient for farming, so it's not like the new neighborhoods are taking farms away from feeding us. So it's more about what we want for our landscape as opposed to competing uses. The main consideration is that when a farm fails or sells, the trees can grow back, but neighborhoods don't quite work that way.
I'm not totally sure where I stand on this issue. Land is there for us if we need it, and restrictions like those in Oregon have proven to limit affordable housing while maintaining natural beauty. The problem around here is that our standards are non-existent, meaning developers build or use a narrow road as a single entrance to a huge neighborhood that adds congestion requiring wider roads that now also need gas stations and Walmarts because it takes 15 minutes just to get to the exit of the vast neighborhood, so roads are widened, traffic lights are added to intersections, and then more traffic signals are needed for the next neighborhood or commercial development or (heaven forbid) apartment complex, and suddenly there's an entirely new city made up of single-entrance neighborhoods and strip malls. But there's a Kilwins or Keke's, so everyone is happy. At least until the next mega-neighborhood gets built a mile down the road.
I guess what I'm saying is maybe a little bit of planning might help a lot in the long run. People live here in the long run, while developers only care about the short term.
