PERC Research Fellow Catherine Semcer sits down with John Batchelor of The John Batchelor Show to discuss Africa’s Great Migration and concerns about its future. New research shows that the Great Migration is slowly collapsing due to widespread habitat loss. At risk is not only East Africa’s natural heritage but also a wildlife-tourism economy worth hundreds of millions of dollars in direct expenditures. Semcer offers ways this collapse can be avoided, including the use of carbon markets.
