Scientists say they have discovered large flows of pollution are reaching the Great Barrier Reef after soaking into underground water, a finding that could have implications for policymakers focused on cutting pollution from river catchments. The new research claims almost a third of dissolved inorganic nitrogen and two-thirds of dissolved inorganic phosphorus in the reef’s waters are coming from underground sources – an amount previously undocumented…

Sponging Up Plastic Pollution – Hakai Magazine

For millennia, humans have used dried natural sponges to clean up, to paint, and as vessels to consume fluids like water or honey; we’ve even used them as contraceptive devices. Whether synthetic or natural, sponges are great at ensnaring tiny particles in their many pores. And as scientists around the world are beginning to show, sponges’ cavity-filled forms mean they could provide a solution to one of our era’s biggest scourges: microplastic pollution….

Seaweed is mucking up beaches. This robot could stop it — and fight climate change – NPR

Sargassum sacs (by John Turnbull CC BY-NC-SA 2.0 DEED via Flickr).

In shallow waters, sargassum can smother coral reefs and alter the water’s pH balance, killing off local seagrasses and mangroves. It can choke boat motors, constricting local fishing yields if not cutting off whole marinas. Sargassum once clogged a desalination plant so badly that residents of the U.S. Virgin Islands were told the drinking water may not be safe…

Don’t look away: This book is a wake-up call to our ‘monstrous’ waste crisis and how to solve it – EuroNews

I’m only three pages into Wasteland when a stat first unnerves me: “It is forecast that by 2050 we will be producing a further 1.3 billion tonnes [of waste] a year.”

It already feels like the world is weighed down with waste. And I’d (somewhat naively) hoped that, given today’s talk of sustainability, recyclable materials and circular economies, we’d be headed the other way by 2050 – towards a less wasteful world…
