The remains of one of our ancestors, Lucy of Africa, date back about 3.2 million years. Slowly the earth’s population grew until it reached a billion in 1804. Obviously we can’t date it exactly, but close enough. By 1927 we reached two billion. .When I was born in 1942 the world’s population had not yet reached three billion.
In my lifetime the population has jumped by five billion people. The U.N. says it has just reached eight billion, and most of that growth is occurring in the world’s poorest countries. Given those statistics combined with global warming, I’m getting out just in time.
I do worry about our grandson, however.
