Science and technology play important roles in the nature and quality of our lives, so it is not surprising that as a society, we are increasingly challenged by problems that have a scientific component. Individual decisions about vaccines, regional choices about water availability, or global agreements about climate change all require that science have a voice during the decision-making process. The microbial sciences touch upon such a wide range of issues that scientists in those fields are particularly relevant to these discussions. If scientists do not participate in these dialogues, then others will fill the void and the information may not be accurate or science based. Scientists must communicate about science with public audiences in order for members of the public to make informed decisions about the complex issues that face us in our technologically advanced society.
