"Reducing greenhouse gas emissions, nutrient runoff and organic carbon inputs (for example, raw sewage loading) would slow or potentially reverse deoxygenation," they write.
And what exactly is "raw sewage loading" they talk about as a way to reverse this? I did some quick googling and couldn't find anything about what exactly it is.
Raw sewage contamination is a huge problem:

Don't go swimming too soon after it rains if you want to be safe from E. coli. Overdevelopment, underfunded utilities, and factory farms put runoff at a level that's barely tolerable when it's dry, and when there's excess surface water, they overflow in unsanitary ways that result in nutrient blooms and oxygen depletion.
A big problem in all of these is adding nitrogen and phosphorus to the water, which facilitates algae growth, which consumes a lot of the available oxygen:

Urine and feces are great sources of nutrients - good if you extract them, sterilize, and use responsibly on land, not good if you dump directly into water.
the solution is attempted dilution,thus:
>>It's literally what it sounds like: dumping untreated sewage into waterways and oceans.<<
In other words, stop letting raw sewage out into rivers. We’ve been working on that for decades.
There are certainly technologies these days that allow you to filter the effluent to make it less harmful to the environment.
