The effects of plastic bag bans on bird populations - Feb.12

Tern with plastic bagWe all know the horrific impacts of plastic bags on marine wildlife, but do you know the impact of plastic bag bans?  In 2007, San Francisco became the first major city to ban single-use plastic bags, and over the next decade, many other cities and counties across California followed with their own bans. 

On Wednesday, February 12, Erik Nesson, Associate Professor of Economics, and Rebecca Conrad, a senior economics major, will share their research examining the effect of plastic bag bans on seabird populations.

Over the past few months, they have been using data from the Audubon Society Christmas Bird Counts across California to examine whether these bans impacted seabird populations.  Interestingly, they have found that San Francisco’s ban led to large increases in seabird populations but that later bans in other locations did not affect seabird populations.  Come to our February chapter meeting to learn full details. 

Chapter business and refreshments will begin at 7 p.m. at Kennedy Library, followed by Erik and Rebecca’s program at 7:15.
