When faced with the thought of being eaten by a fish, however, people rarely behave rationally, which is why Recife, Brazil’s, thoughtful, humane, and effective response is such a refreshing change. After construction at a local port forced sharks to find new homes, shark attacks, some deadly, spiked. Instead of panicking, Recife caught the sharks and moved them away from the human-infested waters.

An outlook report by the Great Barrier Reef Marine Park Authority (GBRMPA), the government agency tasked with overseeing the reef’s health, declines to mince its words. The reef is an “icon under pressure” that has suffered a dip in health since the last major analysis of its condition in 2009.

Climate change, which is causing the oceans to warm, is cited as the leading threat to the reef, followed by pollution running off the land into the sea, coastal development and direct impacts such as fishing.
