how do plains occupy only half of the world's total land and still upport 90% of the world's population

Answer 1

Quite simply because they are very fertile and can produce the highest yields of food.

Answer 2

Well, you see, plains have extremely fertile soil and favourable temperature. Beaches too have favourable temperature but they are not as widespread. Also, there is the convenience of easy transport. Plus, some plains which lie in close vicinity of the mineral-rich mountaneous areas have the facility to get cheap minerals. Did you know that transportation of something accounts for almost 40% of the total price of the goods.

Answer 3

You can grow high yields of crops on the plains. Also the soil is very fertile with great counts of nitrogen in the soil. It is easier to plow and maintain and place buildings on.

Answer 4

Easy. I read a statistic once that said if you gave every man, woman and child on the earth a square foot of ground to stand on you could fit them all within the city limits of Jacksonville, Florida.
