In the process of environmental protection, Rachel Carson’s science communication activities played an essential role as a “whistleblower”. The specific impact of science communication on the development of DDT technology is often underestimated. However, by analyzing the history of DDT and quantitatively assessing Carson’s contributions, we can more accurately identify the influence in industrial production and technology research. The research reveals two core focal points: first, to disseminate environmental risk warning to the public and promote the environmental protection movement; Second, to encourage scientific researchers to reflect on technology and constantly stimulate technological innovation, so as to fundamentally alleviate the social issues caused by the application of technology.
