Which of the following is considered as a "Positive" side of large population?

Can be converted to human resource

'People as Resource' is a way of referring to a country’s working people in terms of their existing productive skills and abilities. Like other resources population also is a resource — a 'human resource'. This is the positive side of a large population that is often overlooked when we look only at the negative side, considering only the problems of providing the population with food, education and access to health facilities. When the existing 'human resource' is further developed by becoming more educated and healthy, we call it 'human capital formation'
