According to the Food and Agriculture Organization of the United Nations, animal agriculture accounts for more greenhouse gas emissions (GHGs) than any other human activity, including even transportation. Yet, the topic is almost wholly ignored by many leading environmental figures and advocacy organizations. This seminar addresses the factors that make animal agriculture the single largest contributor of GHGs, investigates the dearth of attention paid to this crucial issue, and assesses possible solutions to animal agriculture's environmental impacts, ranging from dietary change to in vitro meat technologies. The discussion will be led by Ryan Shapiro, a graduate student in the MIT Doctoral Program in History, Anthropology, and Science, Technology, and Society (HASTS).
