Deoxygenization is happening. Dead zones are increasing in number and size.

"Oxygen levels in the world’s oceans have already dropped more than 2 percent between 1960 and 2010, and they are expected to decline up to 7 percent below the 1960 level over the next century."

Union of Concerned Scientists: The Hidden Costs of #IndustrialAgriculture

Published Jul 11, 2008 Updated Aug 24, 2008

Industrial farming is bad for the health of workers, eaters, and downstream neighbors. Here are some of its costly health impacts:

• #Pesticide toxicity. #Herbicides and insecticides commonly used in agriculture have been associated with both acute poisoning and long-term chronic illness.

• Water #pollution from #fertilizer runoff contaminates downstream drinking water supplies, requiring costly cleanup measures with an annual price tag of nearly $2 billion.

• Loss of mid-sized farms. Once the backbone of US agriculture, medium-sized farms are a dwindling breed, which means that fewer and fewer people make their living as farmers—a trend that has been bad for the economies of rural communities and farm states.

• Harm to neighboring and downstream economies. Industrial agriculture can pack an economic wallop hundreds of miles from its origin—just ask local governments and utility managers who must install expensive equipment to remove fertilizer by-products from public drinking water supplies. Or ask people who make their living from fisheries or tourism on the Gulf of Mexico and elsewhere, where "dead zones" and toxic #algae blooms caused by farm runoff do damage with an annual price tag in the billions. CAFOs, too, create pollution problems that reduce livability and depress property values in surrounding communities.

4. Biochar reduces the very serious problem we have with nutrient run off. #Nitrogen and #Phosphorous are important limited resources that currently leach out with each rain creating oxygen-deprived #DeadZones in streams, rivers, and the ocean along with toxic algae and seaweed blooms like the big one currently headed for Florida. Nutrients are held in biochar so they don’t wash away and less frequent applications are needed - saving farmers $$.

What do #BigAg, #ViolentRanchers, and their#CorruptPoliticians have in common? Billions in federal $subsidies to #WasteWater with export free-trade ready #ThirstyCrops during #droughts, polluted #drinking water supplies with farm #chemicals, destroyed #habitat for rare species, #PesticideDrift, #deadzones from runoff, #ICE to #criminalize and exploit #farmworkers, 34M #foodinsecure Americans, and dammed and destroyed rivers.

"#Fertilizers filled with the nutrient boosted our ability to feed the planet. Today, they’re creating vast and growing #DeadZones in our lakes and seas."

Between 2003 - 2020, coastal phytoplankton blooms increased by 13%, covering an additional 4 million square kilometres of the global ocean, the Nature study found. Blooms occurred more often, up by 59% during that period.

Blooms are toxic in large amounts, starving the ocean of oxygen, leading to "dead zones" that wreak chaos on the food chain and fisheries

Toxic run off from human activity

Oceans die;we die.

400 dead zones around the planet, where nothing lives

Run off from construction sites, Gas and Oil waste water, agriculture waste and fertilizer run off, plastic waste and production.

We are literally killing the Ocean. Thing is that means we will kill ourselves.

It’s all connected

"Researchers have created a #map of oceanic " #deadzones " that existed during the #Pliocene epoch, when the Earth's #climate was two to three degrees warmer than it is now. The work could provide a glimpse into the locations and potential impacts of future low oxygen zones in a warmer Earth's oceans."

"A dead zone in the ocean is as bad as it sounds. Being clueless about dead zones scope and path is worse. Scientists at Michigan State University (MSU) have discovered a birds-eye method to predict where, when and how long dead zones persist across large coastal regions".

Oh, #shit! #Hurricane #Florence is going to #NorthCarolina, which has the some of the world’s largest #FactoryFarms and #CAFOs and, therefore, also the source of billions of tons of #AnimalWaste that will get redistributed.
