IMO, looking for a high tech solution to a low tech problem is a dead end (possibly in the literal sense!)<p>This is a human behavior problem. Consume less; ie growth at all costs is not a long term strategy for the planet. Don't define your happiness with things.<p>I was reviewing the US tariff lists and was thinking, what if all these items were just completely unavailable forever? I couldn't find any examples in the list of products I absolutely must have to thrive. Think of all the carbon saved (and landfill, and ocean plastic, etc) in producing all this stuff.<p>Maybe algae in the Sahara will be a silver bullet, but I'm not holding my breath.<p>I would instead spend resources educating and supporting farmers on sustainable agro, support a transition from a consumer-driven economy to one that is sustainable (also probably education). Promote/support sustainable, local plant-based diets. Etc. I'm happy to invest in scalable solutions in these areas!
