What a weird country, on the one hand they want to save environment from plastic pollution. On the other one tho.. invest in coal power plants, which will only make drought issues bigger.

Trust me, a lot of Australians hate the current leadership and would love to see them gone. Unfortunately we are tending towards the trial version of USA.

800 pounds in a couple of weeks... kind of dispells the notion that it's not coming from western countries.

800 pounds? China pumps 4,800,000,000 pounds (2.4 million tons) of plastic into the ocean each year. No, western countries are not perfect. Yes, the vast majority of ocean waste comes from poor, non-Western countries. The US, 3rd largest country by population, is #20 for ocean pollution. China alone produces 1/3 of all ocean waste. https://www.scientificamerican.com/article/world-s-oceans-cl...

A lot of that was probably imported western trash. In terms of trash production I would guess US is way higher. Just a guess though.

Western countries export most of their plastic waste to the countries named in the article. Substantial amounts of the plastics China spills into the ocean are ours, exported there for “recycling”

But didn’t the public just vote for coal?

But who puts them into the water?

Inconsistencies in environmental standards aren't uncommon globally. Even environmental leaders like California have, what I would consider to be, inconsistent water usage policies, even if it does consistently evolve technology to facilitate those policies.

Australia exporting coal to India and China is far more likely to be having climate change impact than anything it might be doing domesticaly in terms of power generation.

This merely puts the plastic pollution somewhere else (into a dump near the ocean most likely), so it doesn’t really save anything. The problem is still the production of the materials in the first place.

Of course if we didnt use as much disposable things there would be less trash.

But wouldn't you rather have all this garbage collected somewhere, than scattered throughout the river and beyond?

Interesting, I'm curious about the impact on wildlife and the way they switch the full nets for empty ones. They imply there's an overflow system in place I'd love to know how that works More info on the company manufacturing those http://stormwatersystems.com/trash-traps/ They also make trash collecting bots boats.

At least one of the pictures shows the nets are on pipes that drain an open cistern. It appears that if the nets get clogged, water will fill the cistern and flow over, bypassing the nets. Seems like a fairly reasonable fallback solution until the nets can be cleared and put back into action. Other pictures show netted pipes that don't appear to have such a cistern, so I do wonder how overflow is handled in those cases - maybe a cistern upstream that's not visible?
