I completely agree that we need to protect the whole biosphere, so please s/crops/biosphere, that was my bad.
At this point, sadly, geoengineering may be a necessary part of protecting it. We're on the verge of positive feedbacks that could take things out of our hands, as the planet starts emitting vast amounts of greenhouse gases with no more help from us. If all we do is stop emissions, there's a good chance that we'll cross that tipping point before we're done. It's possible that we've already crossed it.

- DennisP 5y agoFrom the articles I've seen, about a year, maybe two. Similar chemistry to olivine I think, but the idea is to use more concentrated CO2 from DAC or fossil exhaust, and pump to basalt formations deep underground. The olivine schemes I've seen use it as beach sand, absorbing CO2 from air in a weathering process.
