@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis There is also the near-absolute worst case scenario where outdoor agriculture becomes untenable due to wildly inconsistent post-climate weather and the "land sharing vs land sparing" debate is forced down the land sparing route, i.e. if most food can only be grown in heated greenhouses, we'll need vast amounts of energy. In that scenario we may well need more nuclear. But if it's that bad that fast I have my doubts that civilisation can survive the transition; that sort of agriculture is very capital intensive as well as energy intensive, although it is higher yield and makes space for rewilding, and potentially could be our only option if things get really bad.
PS I am not endorsing climate controlled indoor agriculture here. I don't have a clear view on the land sharing vs land sparing thing. I know which side most "degrowth" people would take though.

I think you do not realize how much of our population only exists because of Haber and Bosch.

It appears necessary (or inevitable) to shift our #culture towards #collectivism, which would entail radically different rates and modes of #consumption, and collection and use of #public funds. If large #states can't keep up, we need smaller ones that adapt and learn from each other. Material is abundant, we need to #distribute as it's needed. I agree with the urgency you express. Do you believe there is a path to avoid disaster?
@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis I'm not 100% sold on either view of agriculture, as I hint at above. Certainly organic farming goes too far - yields matter, because increased land use ultimately means more deforestation. However if yields are achieved through ecosystem destroying pollution and soil degradation that ultimately reduces yields, there's a problem.
Short term, hydrogen isn't a means of storing energy, it's a vital industrial ingredient, including for fertilisers, which mostly comes from fossil gas.
Cover crops could be introduced with a net increase in yields, while storing vast amounts of carbon, but generally cannot be afforded without a specific subsidy because our agricultural system is broken.
Not to mention the immense waste caused by biofuels. And by meat and dairy.
So there's lots to discuss there as well. (But not today)
