C In the term of Egypt, one of the thing that shows us is there is a lot of land in Egypt for people, to live they are not all clustered together they can be spread out. !

A comparative study of trabecular bone micro-structural measurements using different CT modalities. Some figures state that a single person can survive for a year on crops from about half an acre (a large garden), and there are 640 acres in a square mile, so it looks like only 1450 people per square mile could be fed. Sixty percent of Bangladesh's land area is arable, the highest ratio in the world (Ukraine is 2nd, India is 5th).
