Space Required for the Human Population

If everyone in the world stood next to each other, 4 people per one square meter the entire population would fit on an area the size of the Istrain Peninsula. If each person was provided with a space of about 1,000 square meters to grow food for themselves the entire human population would fit on an area equivalent to the size of Brazil. If each 4 member family were privide with a space of about 700 square meters to grow food for themselves the entire human population would fit on an area equivalent to Iran. In 2019 it was estimated that there were approximately 7.7 billion people in the world. Almost all the necessary vegetable quantities for a four member family can be produced on about 200 square meters of garden space. It is known that arable land currently covers an area of about 31 million kilometers. On this land the vegetable quantities needed to feed 155 billion people or over 38 billion four member families could be grown. There are not too many people there is more than enough space for everyone, except for greed.
