https://en.wikipedia.org/wiki/Regulatory_capture I mean, if the sidewalks outside your house were government controlled, the most likely people to try to take control of them would be people with an interest in making money from them (somehow). Most people don't enter government to be the "Minister of Forestry" without some previous industry experience, and a plan of what to do with the forests. The people with indus…

Ocean oxygen depletion (and atmospheric oxygen depletion as marine life like plankton dies with a double whammy of reduced oxygen and greater acidity) comes up in the scarier corners of climate change awareness but I've never known if it was something to take seriously or if it was overblown. Will we stop being able to breathe?

Yes, we have 2 years left until everyone in the world (except the super rich who can afford bottled air) will suffocate and die

On the bright side, our carbon emissions will go way down

The article says that tree roots released massive nutrients into the oceans during the period of decay causing algae bloom depleting the Oxygen and triggering the extinction. Why just the roots and not the entire trees? Wouldn't the entire tree be decayed and end up in the ocean?

Yes, but trees were not really possible until roots evolved.

> others have made the argument that pollution from fertilizers, manure and other organic wastes, such as sewage, have placed the Earth’s oceans on the “edge of anoxia,” or a complete lack of oxygen.

This is nonsense, obviously. Would apply only for shallow bottom or fresh waters

Terrestrial animal life actually evolved during the Devonian.

From the abstract of the paper linked in the article: "A full-scale OAE would take thousands of years to develop, but some of today's processes are reminiscent of those thought to have promoted OAEs in the distant past." (OAE = oceanic anoxic event) https://www.science.org/doi/10.1126/science.aaj2321

Hmm will be for the super rich for sure. Lets say one air canister is 160 breaths. And this canister is premium lol, and cost 32 bucks. cost per breath is $.20. Avg person = 16 breaths per minute. Cost per minute : $2.30. Cost per hour $192. Cost per day $4608. Cost per year: $1,618,920!

Don't be ridiculous. As President of HN, I can assure both you and the other readers that there's absolutely no air shortage whatsoever. Yes, I've heard the same rumors myself! Thanks for calling, and not reversing the charges.
