As many as 1 billion people across the planet depend on
coral reefs for food, coastal protection, cultural practices,
and income [1, 2]. Corals, the animals that create these
immensely biodiverse habitats, are particularly vulnerable
to climate change and inadequately protected. Increasing
ocean temperatures leave corals starved as they lose their
primary source of food: the photosynthetic algae that live
within their tissue. Ocean warming has been impacting
coral reefs around the globe for decades, with the latest
2014-2016 heat stress event affecting more than 75% of
the world’s corals [3, 4]. Here, we discuss the benefits
humans derive from healthy reefs, the threats corals face,
and review current policies and management efforts. We also
identify management and policy gaps in preserving coral
habitats. The gain and urgency of protecting coral reefs
is evident from their vast economic and ecological value.
Management and restoration efforts are growing across the
globe, and many of these have been influential in mitigating
local stressors to reefs such as overfishing, nutrient inputs,
and water quality. However, the current trajectory of ocean
temperatures requires sweeping global efforts to reduce
greenhouse gas emissions in order to effectively safeguard
the future of coral reefs. The U.S. should stand as a world
leader in addressing climate change and in preserving one
of the planet’s most valuable ecosystems.
