Overpopulation is no doubt worldwide concern as it brings different problems to urbanization process as well as environment. Waste is number one side product of overpopulation. Waste generation is ever increasing in both urban and suburban area and has led to many environmental issues. Many of the waste generated have potential to be transformed into value added products. By recycling, reusing ...

A kinetic model for the Boltzmann equation is proposed and explored as a practical means to investigate the properties of a dilute granular gas. It is shown that all spatially homogeneous initial distributions approach a universal "homogeneous cooling solution" after a few collisions. The homogeneous cooling solution (HCS) is studied in some detail and the exact solution is compared with known ...

This paper defends the Famine Relief Argument against Having Children, which goes as follows: conceiving and raising a child costs hundreds of thousands of dollars; that money would be far better spent on famine relief; therefore, conceiving and raising children is immoral. It is named after Peter Singer’s Famine Relief Argument because it might be a special case of Singer’s argument and becaus...

This paper considers the problem of pet overpopulation. It develops a tractable dynamic model whose positive predictions square well with key features of the current U.S. market for pets. The model is used to understand, from a welfare economic perspective, the sense in which there is \overpopulation" of pets and the underlying causes of the problem. The paper also employs the model to consider...

Those of us who are deeply concerned about population and the environment — "econuts," we're called, — are accused of seeing herbicides in trees, pollution in running brooks, radiation in rocks, and overpopulation everywhere. There is merit in the accusation. I was in Calcutta when the cyclone struck East Bengal in November 1970. Early dispatches spoke of 15,000 dead, but the estimates rapidly ...
