This is unsustainable – population growth.

When I was born (1966) the population of the world was 3.5 billion. It is now 7.3 billion. The U.N. says the world population in 2050 will be just short of 10 billion.

In 1966, the population of Australia was 11.2 million. Today it is 23.7 million. Australia’s population is projected to increase to between 36.8 and 48.3 million people by 2061.

You can work out the rest.
