- There are no pearls growing on the oyster reefs in San Diego Bay, but scientists hope they will yield an even more valuable treasure: protection against coastal erosion wrought by rising sea levels.
- And like the oysters, these long-filament seagrass beds will also provide a crucial food source for the 80 species of fish and 300 varieties of birds that make their home in the area.
- In this context, “We have to make sure that we’re resilient,” said Jason Giffen, vice president of planning and environment for the Port of San Diego.
