The millions of seabirds that call Hawaii home mostly live in the far-flung Northeastern Hawaiian Islands, away from humans and predators. But they are facing an uncertain future, as the low-lying islands on which they nest are being consumed by sea level rise, their nests are being washed away in weather events and they're suffering as the temperatures get hotter. But over the past few decades, environmental groups have been helping bring them back to Hawaii's main islands and the benefits could be shared by all.
