• Improve individual health. ment ladder must continually seek to push beyond what they already have. In this way, they can retain an advantage in the world of commerce and continue to improve the quality of life of their populations. Countries in the scientifically lagging group tend to be at the bottom of the development ladder. Promoting rural economic development, improving public health, and reducing the use of resources and improving environmental health commonly rank highest on national agendas. All five applications could also help these countries use fewer resources and improve environmental health. Cheap solar energy would provide energy without fuel combustion, reducing environmental emissions. Solar energy and cheap autonomous housing might help reduce the indoor air pollution generated by wood- and coal-burning stoves. Less reliance on firewood would promote healthy forests that would help control soil erosion; improve the quality of underground water; reduce sediment flows into rivers; and supply food, medicine, and con-struction materials. Rural wireless communications could help local and national governments monitor resources, environmental conditions, and pollution. GM crops would help conserve the natural resources used for agriculture and eliminate or reduce the magnitude of sources of pollution. Filters and catalysts would help conserve water and reduce waste streams. Cheap solar energy, rural wireless communications, GM crops, filters and catalysts, green manufacturing, and hybrid vehicles could enable nations in this group to reduce the use of resources and improve environmental health. Again, the benefits would be the same as for the scientifically lagging countries. In addition, green manufacturing would diminish waste streams, allowing energy, water, and land to be used more efficiently; cut down pollutants in the environment; and reduce the burden on local governments of cleaning up polluted areas.
