With the way the human population is expanding and the rising income of 3rd world nations we are really going to look at a major increase in both genetically engineering food stock to be larger and more nutritious as well as ramping up lab grown meat. Conservation is clearly not going to work as so many nations ignore it anyway and quite often regulations lack teeth due to the fear of killing an industry. Its difficu…

Yup. We're already pretty much at capacity in terms of using arable farming land[1]. We need more efficient farming, which means GMOs and advanced farming methods; we don't need less efficient farming like organic and anti-GMO. [1] https://theness.com/neurologicablog/index.php/how-much-arabl...

We could try harder not to lose or waste food that we produce: FAO estimates that each year, approximately one-third of all food produced for human consumption inthe world is lost or wasted.[1] (Note that this is not just about people throwing away food they bought, though it's a big part of it.)

And at first glance it seems obvious that eating less meat, globally, is going to increase available calories/area; the fact that some areas are viable for livestock but not vegetables notwithstanding. About half of the area used for agriculture is used for livestock, if I read [2] correctly.

I buy canned sardines regularly. I've noticed for the last year that the size of the sardines are increasing, and many that are canned now have eggs. It makes me wonder if pressure is making them age and try to reproduce sooner than before, or if the fishing season is being expanded to meet demand. I've cut back on buying them as much. I may quit after this.

Could just be that there are more of them, due to less predators (the bigger fish), therefore the average size is bigger/older

>A science fiction style solution is going to be the only way to feed the world. I get what you are saying, I just want to clarify: we can feed everybody now, but mostly with vegetables. But yes, shared resources like ocean fish are under too much pressure right now. I feel as though it will take a major worldwide collapse of the fishing industry before there is better enforcement and treaties.

As a resident of a first world country I stopped eating all seafood about 15 years ago. It seems unethical to support over-fishing if I have plenty of other good food to eat.

Earlier quoted context omitted.

> Society just wont change to support it. Maybe this is just me, but I would happily change my diet to be around 50% Soylent or other meal replacement if the cost was cheaper. Currently I eat around 2400 calories a day, with Soylent that costs me $20 a day. I can get Chipotle for ~$15 per day, and between the two Chipotle clearly wins on taste. From what I can tell meal replacements are often far more environmentally…

The price for Soylent you quoted is for pre-prepared bottles. You can get the add-water-only version for much cheaper. In fact, you can get a day's worth of calories for about $10 even with better quality formulation competing products such as Huel 3.0 or Plenny Active. You literally scoop the powder into the provided bottle with the provided scoop they give you, fill it with water, shake it up for 30 seconds, and it…

I hadn't heard of Plenny Active before, looks like you're right about the price. I'll have to give that a try, thanks for the suggestion!

Though we could feed many more people with current farming capacity if we ate all the corn we grow ourself instead of feeding it to cows that we eat. Meat production is incredibly inefficient.

If we eventually manage to produce most of our meat demand from lab-grown meat this will likely free up enormous amounts of agriculture capacity.

> While I wish organically growing food and conservation was the answer, its unfortunately not.

I recently had a lengthy discussion with some friends about their support of a solidary organic farm, where you pay a flat fee per month and get a box of whatever they have in that week. It's really hard for most people to understand that things like these are not sustainable and that it's purely a luxury product. Terms like "organic", "no GMO", "local" sound sustainable as you imagine going back to "the good old days", but it's just impossible to feed the world. Even after I quoted some facts about the needed land usage for organic, it was not really possible to convince them, that it's not sustainable.

If anybody has some good articles / studies about sustainable farming for the future, I would love to read them.

Why science fiction and not plain old fish farming?

And/or an international agreement to reduce fishing, and outlaw the import of fish caught outside the bounds of that agreement.

Similar international agreements have worked relatively well to cut down on things like chemical weapons and anti-personnel mines.
