In my book Hunger Math: world hunger by the numbers, I analyzed over 120 crops to find the most productive sources of each macronutrient: protein, fat, and carbohydrate. In other posts on this blog, I’ve discussed the need for dietary fat and the most productive fat crops. Here I’d like to deal with the issue of protein crops.
#1 on the list:
Duckweed (water lentils), at a high estimate of yield (30 t/ha), far out produces other crops for kg of protein per hectare per year. At a low estimate of yield (10 t/ha), the crop still makes the top ten list of most productive protein crops. The yields listed as high and low are on a dry matter basis (DM), i.e. calculated after neglecting the weight of water content.
The U.N.’s Food and Agricultural Organization (FAO) cites a paper from the Centre for Duckweed Research & Development at a University in Australia: “When effectively managed in this way duckweeds yield 10-30 ton DM/ha/year containing up to 43% crude protein, 5% lipids and a highly digestible dry matter.” [Duckweed – a potential high-protein feed resource for domestic animals and fish; Leng et al.]

That's obviously very similar to how we've been able to advance. With agriculture came the ability to feed many with less manpower, which freed people up to pursue other things, which led to technology leading to even more people being able to not focus on feeding themselves.
My admittedly very limited understanding is that it's not that we can't grow enough food, but getting it to certain areas is the problem because of cost. Like everything else there are also a ton of other variables.

Ok. Thinking utopian paradise here, so you far to right wingers who wants everyone to slave for food won't like this idea. Just warning you.
So there's a lot of poor and starving people in this world who are left out of the economy. I'm not talking just the US I'm talking the entire world. Either their resources are being stolen by Rothchild managed mining companies in Africa and Sourh America, or their country is in chaos in the Middle East, or there is a caste system like in India, or the United States, or the various other causes for world hunger.
Finance being the main reason why people starve, not lack of resources.
If you've been paying attention, which a few of you have, you know we are losing jobs in the western world. The main reason being technology! We are losing millions of jobs to automation and will continue to do so. Because of this there is a massive divide forming between the haves and have nots (almost everyone is a have not).
So we have issues to face now. At what point do we finally say that enough is enough and everyone on this planet gets food, water, and a place to live. Weather it's a lot of land they have to figure out what to do with or a thatched hut whatever.
So ATS, how do we feed everyone?
