ON AIR: Phil Carter - One Step Forward, Two Steps Back

03/19/13 An Audio Interview with Julie West, MLF Broadcaster

In this edition of our audio podcast ON AIR, MLF Volunteer Julie West interviews mountain lion program manager Phil Carter of Animal Protection of Wyoming. Carter discusses the often ridiculous lengths the Wyoming Department of Game and Fish will go to to disregard the public, bury scientific research, and ignore all common sense. Trying to protect mountain lions in Wyoming and incorporate the best science into management has turned into a game of one step forward, two steps back.

Environmental Scorecard

League of Conservation Voters

The League of Conservation Voters' scorecard considers the State Legislature's environmental records since 1971. It quantifies the environmental votes of each individual legislator — an important first step in considering accountability — and provides critical qualitative assessments as well. The scorecard will help you to know your legislator before you write a letter in support of cougars.

Becoming a Mountain Lion Activist

There are lots of opportunities to take action!

Are you new to mountain lion activism? You want to change your local environment to improve it for cougars... but you don't know how to start. You may feel like you are all alone... but it takes just one person to change the attitudes and lifestyles of hundreds of others. You don't need to belong to a group. It doesn't take special skills or superhuman abilities. You just need to care enough about cougars to want to help them survive. You've already done the hard part, now let us help you with the next step.
