Background<br />
Shallow tropical coral reefs and sea grasses play important roles <strong>in</strong><br />
coastal carb<strong>on</strong> and nutrient cycles, <strong>in</strong> coastal biodiversity and <strong>in</strong> the<br />
ec<strong>on</strong>omy <strong>of</strong> coastal z<strong>on</strong>es<br />
The global surface area <strong>of</strong> both coral reefs and sea grasses has<br />
decreased by ~30% <strong>in</strong> the last 100 years<br />
