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.

Mountain Lion Retreats Back into Foothills

06/02/12 A 2-minute video by CBS Denver

A mountain lion that was in a tree in Morrison all day Friday has finally retreated back into the foothills, but earlier even some deer were not enough to lure the animal down. The mountain lion climbed up in the tree about 8 a.m. Wildlife experts wanted the animal to take off on its own. They didn't want to tranquilize him because he didn't do anything wrong.

House Cat Stares Down Young Cougar

10/20/11 A 2-and-a-half-minute video by the DenverPost

While trying to get some work done in home in Boulder, Colorado, Gail Loveman turned around to find Zeus (her Maine Coon cat) staring down a juvenile cougar through the sliding glass door. Zeus casually sat by the door watching as his larger cousin curiously pawed the glass and bounced around.

Environmental Scorecard

Conservation Colorado

The Colorado Legislative Conservation Scorecard highlights the priorities of the conservation community in the current legislative session. Here, you will find factual, nonpartisan information on bills related to our environment and how each member of the legislature voted on issues that affect Colorado's air, land, water, and people. Find out how your elected officials voted, and see how well their votes align with your conservation values. We encourage you to call or write to your legislators and let them know you're paying attention to their environmental scores!
