HURRICANES/ EXTREME WEATHER:
Extreme weather- hurricanes, droughts, floods, etc.- damage and destroy crops. Hurricane Katrina did $2 billion damage to agriculture, not including the devastation to the shrimp and sea crops of the fishermen.
Wilma followed, causing a possible additional $2 billion to Florida's citrus, avocados, vegetables, sugar cane, with more damage expected from diseases spread by the winds. Avocadoes are mostly coming from Central America now.
