The interrelation between molecular biology and plant life has gained the attention of scientists and public officials concerned about the environment. As a result, support for this academic discipline and its research projects has been increasing over the past several years. Other research scientists have found similar importance in their study of microbes, advising conservation of resources in very specific ways. Smith and Williams are two among several dozen scientists who have formed an organization called Microbes for the Future of Planet Earth, dedicated to raising funds for continued research. Because this field of research has become so important for the environment, the federal government should increase its support for microbiological studies.
