182 Superlongevity Without Overpopulation bodies of water is an example of this. The desertification of collectively or government owned land in Africa is another. We can be reasonably confident that the trend towards less pollution  with  greater  population  will  continue.  However, complacency is out of place. We should press for responsible management  of  resources  by  privatizing  collectively  owned resources  to  create  incentives  for  sound  management  and renewal. So long as we continue to allow freedom to generate more wealth  and  better  technology,  we  can  expect  pollution  to continue abating. More efficient recycling, production pro- cesses that generate fewer pollutants, and better monitoring and detection of polluters, along with economic incentives making each producer responsible for their output, will allow us to continue improving our environment even as population grows. Assuming that we achieve complete control of matter at the molecular level, as expected by nanotechnologists, we will have the keys to production without pollution. Another product of molecular manufacturing will be the disappear- ance of most large-scale, clumsy machinery. Less and less land will need to be used for manufacturing equipment, making more  room  for  people  to  enjoy.  Some  manufacturing  will be moved into space. The result of these and other changes (some of which are already underway) will be the freeing of the Earth from unwanted, but previously necessary, means and by-products of manufacturing. The  population  issue  raises  numerous  factual,  economic, and ethical concerns. I urge the interested reader to check into the sources listed in the References, especially the essays by Jesse Ausubel [18] and the books by Bailey, Lomborg, and Simon. [3;19;20–25] I have only sketched lines of thinking showing that we would be severely misguided not to push for extended life out of fear of overpopulation. Let us move full  speed  ahead  with  extending  life  span:  Once  we  have
