Why do the corporations pollute so much? Is it just for the love of the game?

To some extent, yes, it is deeply for the love of the game: planned obsolescence, single use products, nothing built to last, "razor blades and ink cartridges" where worse user experiences sell more products, intentional over-production to drive over-consumption through consequent demand for artificially low priced goods ("the Wal-Mart effect"), and so forth. If we don't find ways to price in externalities into the m…

> planned obsolescence, single use products, nothing built to last

Planned obsolescence is a conspiracy theory and there’s no evidence of it occurring at any kind of broad scale.

Consumers generally prefer cheaper, less durable products, which is why the market adapted to better fit that preference.

Solar and wind are fusion generated energy from the sun. “Fusion at a distance.” Fossil fuels are ancient sunlight, ancient fusion.

A step to far my friend. If we abstract away everything then nothing matters.

If you would like to bet how much nuclear will be operating in ten years, place your bet. I’m willing to bet $10k to a charity of the winner’s choice nuclear generation remains about the same total capacity as today while renewables scale to terawatts. Let me know if I should have a Longbet spun up for accountability.

So currently we're at 428 with 3.5 increase per year, yeah, that's scary if it doesn't slow down soon. Makes you wonder about what indirect health side-effects that could have on us.

Chronic exposure to CO2 levels above normal but below acute toxicity makes us dumber and more irritable.

I literally said this down below and got down voted. This has been my theory for a few years now. It's not the only thing, but the flynn effect has certainly reversed.

When the wildfires during COVID hit some folks did some work to figure out how much of a cognitive effect wildfire smoke has on the brain. Its pretty staggering. https://pmc.ncbi.nlm.nih.gov/articles/PMC9196888/ Essentially, this affects every person and animal on the planet.

Literally said this down below and got downvoted... but it's a big deal and nobody is talking about it really - indoor levels are much higher.

This actually has me just as concerned as rising temperatures. And its a pretty hard thing to argue against, no matter your politics. Elon even brought it up when he did that interview with Trump in late 2024 to convince him that we should still care about CO2 levels in the atmosphere, even if you think the threat of a changing climate is overblown. Trump really had no response.

USA (along with the rest of the western world) is a huge cumulative emitter: https://ourworldindata.org/contributed-most-global-co2 But a distant second in per year emissions: https://www.worldometers.info/co2-emissions/co2-emissions-by... The EU, not listed here, sits between the US and India at about 3.05 billion tonnes. It's all up to China, which took over a huge chunk of the world's manufacturing. And all up to…

figuring out who to blame is not the problem here, we need to figure out how to fix it.
