Great exmple of the absolute facile rubbish that certain members of society now have time to waste on thanks to the fossil fuel supported inputs to the rest of their lives. Peak oil is going to make factory farming unviable in pretty short order so I think we will all be forced to reduce the amount of meat we eat anyway. It won't be replaced with this sort of hi tech mush which probably needs a source of animal protein in the nutrient mix.

Ah a breath of sanity! If we're that worried about animals and fish, etc., which we'd not have to be if we're get our own population down, and if we don't want to eat nice creatures like chickens and cows and pigs, then we really ought to get over our cultural taboos about eating bugs.

Bugs look cute but they are basically little robots. There's really no soul to a bug, more of a flow-chart. There's not "anyone" there to wrong, in eating a bug. And generally they're tasty, a real treat. As non-Western cultures will attest. And you can raise them at home. They're not generally smelly or messy, and their manure can be used on the garden.

These high-tech "solutions" are BS,

... WTF?

Or we could just eat less meat. Billions of people eat very little, and manage not to keel over instantly.

I don't think we need eat roaches. But if that's your thing, by all means go for it.

Without wanting to encourage our doomer friends above, I feel the need to point out that some people do eat bugs - in Cambodia I saw people snacking away on fried spiders and roaches quite happily.
