Today's economic thought has identified two impacts of hoarding poverty and war. Mahavira said, "Do not accumulate". If accumulation is kept within limits, the problem of poverty can be solved easily; so also the problems of unemployment and population. If poverty is contained, people will get proper nutrition. With this will end the problem of population. The basic factor is poverty and the outcome of poverty is population growth.
Look at the conditions in developed countries. They are making an effort to increase population. In Russia mothers who produced more children are rewarded. Whereas in China and India efforts are being made to limit the size of families, programmes have been undertaken to increase the size of families in Germany and other developed countries.
