Raskolnikov38 posted:The mass usage of phosphate fertilizers came up during fishmech's age o' corn derail that had me wondering, if most of this stuff ends up in the oceans can't we just extract it similarly to how people have been going on about getting uranium out of seawater? The ocean is pretty big. Getting useful quantities of phosphate without spending ludicrous amounts of energy and/or money is probably going to be, uh, challenging.

LemonDrizzle posted:you need mindbogglingly vast quantities of phosphate to sustain the modern agricultural system Since much of the agricultural runoff enters the sea via rivers, it would be easier to reclaim it from said rivers. Imagine scouring all water coming out of every major river system going through some sort of agricultural area for phosphate.

Forgall posted:What about hydroponics? Are there serious downsides to them? Are they good for growing stuff other than lettuce, like legumes so we could get some protein out of them? Using 1% of water and being able to easily filter out all useful stuff from runoff and reuse it seems pretty great. And they are basically independent of climate.  and possibly energy inputs, mostly.

whitey delenda est posted:This, hydroponic farming takes the problems that I detailed in the OP and actually makes them worse (for the most part). You've got dirt out there, why not utilize it? At the very least, soil is slowly creating more of itself and reclaiming small portions of resources from the environment via deposition effects. The energy problem could be addressed via non-fossil-fuel means, but for the foreseeable future scaling it up to staple farming is physically very challenging. ...and thus starts the  Land sharing advocates for (usually less-intensive) agricultural areas with somewhat intact ecosystems as the best way to feed us without destroying too much biodiversity. Land sparing is about setting aside as much land as possible as protected area and farming the rest for maximal yields. If you embrace the mighty atom  , things like vertical farming would be the logical end point for land sparing.

Peven Stan posted:A lot of old school Han people like my mom hate the taste of ruminants. You can work up a slick marketing campaign but that doesn't change long seated cultural attitudes towards beef and lamb as ethnic meats for the Halal market. A billion people eating more pork is less bad than a billion people eating more beef, so that's alright.
