Director's Lecture Series: Food Waste Policy


Food Waste Policy: Using Systems Change to Stop Squandering One of Our Greatest Resources

Emily Broad Leib, Assistant Clinical Professor of Law, Director of the Harvard Law School Food Law and Policy Clinic, and Deputy Director of the Harvard Law School Center for Health Law and Policy Innovation
1 Session: Monday, February 24, 7:00–8:30pm
Location: Hunnewell Building

More than enough food is produced to feed every person, yet nearly 40% of food is wasted in the United States. This waste squanders our natural resources and has negative impacts on the environment and the economy. The Harvard Law School Food Law and Policy Clinic has been at the forefront nationally in terms of educating about the relevant laws, supporting innovative models to increase food recovery, and driving policy change at the federal, state, and local levels to align incentives to reduce food waste. Emily Broad Leib will share the key knowledge developed by FLPC, providing an overview of the causes of food waste, the key legal and policy opportunities, and a snapshot of current trends in federal and state government approaches to the issue.

Emily Broad Leib founded Harvard’s Food Law and Policy Clinic and is recognized as a national leader in Food Law and Policy. She was named by Fortune and Food & Wine to their list of 2016's Most Innovative Women in Food and Drink. The list highlights women who had the most transformative impact on what the public eats and drinks. Broad Leib was one of the inaugural recipients of Harvard President Drew Faust’s Change Solutions Fund in 2015.

Director's Lecture Series: Enlightenment Now


Enlightenment Now: The Case for Reason, Science, Humanism, and Progress

Steven Pinker, Johnstone Family Professor of Psychology, Harvard University
1 Session: Monday, March 9, 7:00–8:30pm
Location: Hunnewell Building
SOLD OUT. Add name to waiting list at right.

Is the world really falling apart? Is the ideal of progress obsolete? Assessing the human condition in the third millennium, cognitive scientist and public intellectual Steven Pinker urges us to step back from the gory headlines and prophesies of doom, which play to our psychological biases. Instead, Pinker suggests that we follow the data with which he shows that life, health, prosperity, safety, peace, knowledge, and happiness are on the rise, not just in the West, but worldwide. This progress is not the result of some cosmic force. It is a gift of the Enlightenment: the conviction that reason and science can enhance human flourishing.

Fee Free. Members only. Registration required as seating is limited

Steven Pinker won the 2018 Carl Sagan Award for Public Appreciation of Science from the Council of Scientific Society Presidents. The award is given annually by the society to recognize an individual for outstanding achievement in improving the public understanding and appreciation of science.
