Population and Our Planet
A very important world problem is the increasing number of people who actually inhabit this planet. The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate.

It is not so much the actual population of the world but its rate of increase which is important. It works out to be about 1. 6 per cent per annual net increase. In terms of numbers this means something like forty to fifty-five million additional people every year. Canada has a population of twenty million-rather less than six months’’ climb in world population. Take Australia. There are ten million people in Australia. So, it takes the world less than three months to add to itself a population. Let the US take our own crowded country -England and Wales: forty -five to fifty million people—just about a year’’s supply.
