Understanding hurricane effects is the first step to preparing for hurricanes. The effects of hurricanes can be comprehensive and long-lasting, even permanent, at the spatial scales of a single molecule to whole ecosystems. Multidisciplinary collaborations are required to improve our understanding of hurricanes. Here, we review basic facts of hurricanes and their effects in Florida and speculate on how they might affect Florida’s agriculture and natural resources. Examples and speculations provided in this article demonstrate how weather, agriculture, environment, and ecosystem are connected to each other across spatial scales ranging from microorganisms to an entire landscape.
