Problem one.
There are currently an estimated 6 billion people currently living in the world today. If 1/3 of these people got married and all had 2 or 3 children, how big would the population be in 10 years time? A 1/3 of the six billion will die without having children, and 1/3 will have more than 4 children. How many much food would it take to feed these if people on 3 meals a day, and how much land to grow this food, and how many cooks would it take to cook it?
Please show your working out.
