Unlovely seaweed -- which seems to crop up anywhere that mankind's activities contribute to excessive nutrients in the water -- now appears to be encroaching on Australia's unique and wondrous Great Barrier Reef.
Seaweed takes over Great Barrier Reef
Despite their apparent proliferous life, reefs actually thrive in really clear, really low nutrient water (that's why the coral polyps have algal symbionts, natch). So when the water gets more nutrients, this is not prime coral habitat, and it encourages the growth of unlovely seaweed.
Yet another indication that we, collectively, need to clean up our acts.
