Today we looked at a map over the continents and oceans. we will have a test over what we studied tomorrow. I have also learned there is a new ocean called the southern ocean. about 7 billion people live in the world, about 312 million live in the united states, 3 million live in iowa, 12 thousand live in shelby county and 5 thousand live in Harlan Iowa. births minus deaths equals the natural increase of the population which is 78 million a year.
