Sweet Insight: App Helps Farmers Save Great Barrier Reef

One of the greatest threats to the health of the Great Barrier Reef, the world’s largest coral system spanning more than 337,000 km2 (130,000 mi2), is the appetite of a reef-eating starfish measuring roughly 30 cm (12 in.) in length. Although the crown-of-thorns starfish is native to the Great Barrier Reef, it responds similarly to […]
