With modern farming techniques, I think the earth can sustain at least 30,000,000 people.

Quote:

 

If all humans consumed the same as the average Indian does, the earth could sustain as many as 15 billion people. If we consumed as little as the average Rwandan, this would go up to 18 billion. But our planet can only sustain 2.5 billion people living as we do in Britain and only 1.5 billion living in the lifestyle of those in the USA.

vegetarian food have all the essential amino acids in bigger amounts than meat - there's no need to GM them. I

vegetarian food have all the essential amino acids in bigger amounts than meat - there's no need to GM them. It fairly is easy to obtain enough vitamins and minerals too, as long as there's enough variety in the diet. It makes much sense economically as well.

The only other option that is just as good, or even better in some aspects (easier to get fatty acids DHA and EPA), is diet made up exclusively of fish and plants

I agree for the most part, but what about vitamin D? It's the most important of all vitamins & I'm not aware of any plant that has it in sufficient amounts. Milk, fish & liver really is the only good source AFAIK. People with light skin who live in sunny climates don't have to worry, but what about Scandinavians for example, they are under cloudy skies almost 24/7 & can't synthesize vitamin D.

Britain's cloudy enough, and yet 30min of jogging with short shorts and tank top seems to do the job for me and my skin is not even the lightest of light.

Yes they have it but the amount is important, we are made by meat, this means meat have the right proportion of the aminoacids you need, also our digestive tract is not developed to eat such food, we get litle of the aminoacids in the plants, it is a fact, also there are problems with vit B12 and Fe, if you are going to eat only plants, the solution is GM, you can do plant which produse the right compilation of vitamins and aminoacids you need, and also easy digestibal.

human meat proteins differ from pork proteins, so we still have to strap them to basic amino acids and remake them. You don't have to get the full set of amino acids with every meal, although even that is not hard to achieve since lots of plants (beans, lentils, peas, buckwheat...) have the full set and they contain much more grams of protein per 100g.
