ON AIR: Marc Bekoff on Culling Lions

11/10/15 An Audio Interview with Julie West, MLF Broadcaster

In this edition of our audio podcast ON AIR, MLF Volunteer Broadcaster Julie West interviews Marc Bekoff. Marc discusses Colorado's unscientific plan to hunt more mountain lions in the hopes it will increase deer and elk herds. The conversation goes beyond wildlife management to take a deeper look at how we view, value and treat all other animals who share this planet. Perhaps it's time we all stop and analyze the killing of animals from an ethical perspective.

Killing Mountain Lions to Grow Mule Deer

10/01/15 Guest Commentary by Marc Bekoff

Animal expert and biology professor Marc Bekoff discusses Colorado's misguided plan to kill mountain lions in the hope it will increase deer populations. Though it may seem like less predators would yield more prey, there is no science to back the state's plan. In fact, killing large numbers of mountain lions causes chaos and increases ecological problems. Please contact the Colorado Parks and Wildlife Commission and urge them to vote against this plan which would cause significant and widespread collateral damage.
