Fertilizer from farms in Salinas flows into Monterey Bay, carrying phosphates and other nutrients that fuel the growth of algae to the detriment of seagrass leaves.

Thanks to conservation efforts, with sea otter populations returning and crabs in their diet, the food chain is back in balance, resulting in fewer crabs that were wiping out sea slugs, which clean off the algae from seagrass leaves.
