Scientists are claiming chemical substitutes of foods by amalgamating the proteins, minerals, and other supplements but how much they would be able in replacing the natural food is a big question.
Knowledge is power.
Milk and milk-based products are also good alternatives for food. So increasing the population of animals like cows, goats and buffalos is one alternative. We will get more milk and other products.
Synthetically made food substitutes are also thought of by many people. I think Scientists are working on this concept and we may get some positive results on this. Growing more trees which will give us fruits and vegetables is also away. These days we are seeing small kitchen gardens, building top gardening etc. They may also offer a good quantity of food and may come in handy to some extent.
