Australian government to dump 3,000,000 cubic meters of dredged sea-bottom on the Great Barrier Reef

In December, the Australian government approved a plan by India's Adani Group to expand a coal port, and now the government's given the go-ahead to dump the 3,000,000 cubic meters of muck that will be dredged for the project onto the struggling Great Barrier Reef. The GBR, which is a World Heritage Site, is already officially classed in "poor" health, and the ocean floor around it will now be smothered with vast amounts of waste, destroying fragile habitats and crippling a key player in the world's ocean ecology. The Australian government says that the reef will not suffer as a result, but independent scientists who investigated the question firmly disagree.

Mount Everest isn't the only natural wonder experiencing a ridiculous increase in tourism --and, with it, trash, ecological damage, and risk. At the Arizona Republic, Brandon Loomis writes about the massive increases in athletic backcountry tourism at the Grand Canyon. It's easy to see the similarities to previous stories you've read about crowds of hikers on Everest. Just last month, Loomis writes, 224 rim-to-rim hikers — people who march down one side of the canyon and back up the other in a day, a vertical change of 10,000 feet — converged on a rest area all at once.
Bayou Corne, Louisiana is being swallowed by a massive sinkhole. Yes, the whole town. OK, it is a small town. But it's definitely a massive industrial disaster. Tim Murphy reports for Mother Jones.
This stunning lake at Harpur Hill in the East Midlands of England is just begging you to dive in, no? Problem is, the quarry pool, known as the Blue Lagoon, has a pH level comparable to bleach and is teeming with garbage and dead animals. The bright blue hue (and the high pH) comes from the quarry stone. Signs warning visitors not to take a dip didn't work, so now the High Peak Borough Council recently dyed the water black. "It's not pretty any more," local business owner Rachel Thomas told the BBC. "They don't think they're on holiday in the Bahamas any more, they know they're in Harpur Hill."
This fantastically pink slug, Triboniophorus aff. graeffei, is only found on Mount Kaputar, a mountaintop in New South Wales, Australia. According to scientists, the slugs and several other strange species are from the days when this region was a damp rainforest. When Mount Kaputar erupted 17 million years ago, it preserved a very unusual ecosystem. "A series of volcanos and millions of years of erosion have carved a dramatic landscape at Mount Kaputar National Park, creating a fascinating world with some very colourful locals," writes the NSW National Parks and Wildlife Service on its Facebook page.

There's a war on in America, pitting invasive ant against invasive ant in a fight to the finish. It's sort of like Alien vs. Predator, in a way, because whoever wins ... we lose. Argentine ants (the reigning champions) have wiped out native ant species in many of the environments they've invaded over the years, affecting the survival of other animals that used to feed on those ants. Worse, they have a fondness for certain agricultural pests, like aphids. In places with lots of Argentine ants, aphids do very well — and plants do worse.
But now the Argentines are facing a serious challenge in the form of Asian needle ants, another invasive species that — for reasons nobody really understands — have suddenly gone from minor player to major threat in the last decade. The big downside to Asian needle ants: They sting. They sting us. And, right now, it looks like they're winning.
John Roach tells the story at NBC News. But you can get a good idea of what this matchup looks like by checking out the work of insect photographer Alex Wild. That's his picture above, showing an Argentine ant on the left and an Asian needle ant on the right.
