7 billion people

The world's population will hit 7,000,000,000 (7 billion) people on Halloween. When I was born, right after World War II, there were about 2.5 billion people on Earth.

What is the maximum number of people the Earth can support before things fall apart and only the very rich have any quality of life?

What kind of world are we leaving for our children? Good night.
