Not to mention the loss of the 5-storey-tall coconut palms in South Florida back in the 1970's to Lethal Yellowing. The last resort treatment for these was tetracycline too but it did not save them. Plus they were not generally cultivated nor a local cash crop.

These things used form a massive canopy or grove naturally in so many places, towering over the homes and undeveloped properties.

Which is why so many old homes had the 3 inch thick white tiles on the roof. When one of the nuts comes down from up there it hits pretty hard, even if it's not a hurricane.

Almost all virtually gone, and what's there now is really all the result of landscaping efforts ever since, using resistant varieties that are quite dwarf by comparison.
