I have heard in the radio in one discussion between an executor and economist that:

The world of a humans have technology with the ability to feed 200 billion of its kind but the existence of 2 billion of them like children are hungry.

So I have asked here to know is this right and if possible I would like to know some tags for finding some academic papers or media posts about the above context.

    $\begingroup$ Where did you read or hear that the world can feed 200 billion humans? Can you provide a source or citation? $\endgroup$

    $\begingroup$ The FAO has plenty of reports on how to feed 9$-$10 billion by 2050. It will be challenging but doable. Feeding 200 billion doesn't matter, it is not a realistic number of humans in the foreseeable future. $\endgroup$ Oct 16 '21 at 5:49
  • $\begingroup$ @Nic, I have heard it from one online radio and in one discussion with Executor and economist, so I like to know is this technology available to feed around 200 billion humans? $\endgroup$ Oct 16 '21 at 8:24

As mentioned in the comments, 200 billion people is an unrealistic world population. However, according to the FAO and the U.N. (e.g. 1, 2, 3), current levels of food production are more than sufficient to feed today's world population (a similar claim is also included in the 2014 IPCC report).

Many of the reports of the FAO suggest steps in the direction of not having the present contradictions such as the huge amounts of food waste while millions of people are hungry, of keeping food production sustainable, etc. But it should be emphasized that the present levels of food production are already sufficient to feed the global population and that world hunger / undernourishment / food insecurity are not because of scarcity or inability to produce enough for all.
