How do you spread the word on how human population growth and overconsumption are driving the extinction crisis? How does human activity endanger other species? Check out some of our favorite videos below on population growth, spotlighted species, and how some of our volunteers are starting conversations over condoms.


Human Population Growth and Wildlife Extinction

There are more than 7.5 billion people on the planet, and we're adding 227,000 more every day. This video illustrates the toll on wildlife that's impossible to miss. It’s time to talk about our unsustainable population growth, overconsumption and the wildlife extinction crisis. Join the conversation.



Meat production is responsible for more environmental degradation than any other single industry. Learn more about how meat production threatens wildlife and how you can help fight the meatstinction monster.


How Can You Save Endangered Species... In Bed?

Saving wildlife is sexier than you might think. How sexy? Every time you slip between the sheets with that special someone you can be a hero for wildlife – as long as you protect yourself and the planet. Every day, 227,000 humans are added to the planet and in the United States alone, nearly half of all pregnancies are unplanned.



There are nearly 7.2 billion people on the planet today, and our numbers keep growing. That means more crowds, more traffic, more pollution…and less room for wildlife. Watch the Center's video compiling some of our favorite #CrowdedPlanet photos submitted for World Population Day 2014.

Author Alan Weisman Talks Population With the Center

Alan Weisman — an award-winning American author, professor and journalist — speaks with the Center's Population and Sustainability Director Stephanie Feldstein about his 2013 book titled Countdown: Our Last Best Hope for a Future on Earth?


Swipe Right for Wildlife

More and more people these days are finding the love of their life (or just the night) on dating apps like Tinder, which matches you up with other people in your area looking to connect. But wild plants and animals don't have smart phones, to advise them of would-be suitors in the neighborhood or on the other side of the highway.


Purdue Students Bring Condoms to Campus

On Earth Day 2013, a group of Purdue University students — plus one giant hellbender — took to campus to hand out the Center’s Endangered Species Condoms and get people talking about the connection between rampant human population growth and the species extinction crisis.

Interviewer Gets Personal
Dave Gardner, the filmmaker behind Growthbusters: Hooked on Growth, took his camera and his stash of Endangered Species Condoms to talk to people about how what they do in the bedroom affects other species. The result is interesting, informative and, at times, hilarious.

Population or Sustainability?
Laurie Goering talks about global population growth, climate change and why we need to address both population and sustainability. Sound complicated? Laurie sums it up in just two minutes.

The Climate Future
It’s estimated that by 2100 there will be nearly 11 billion people in the world. What does a population that big — and its growing energy consumption — mean for the planet? Scientists visualized what the latest data means for our climate, our oceans and our societies if we don’t start cutting carbon emissions now.

The History of World Population
People have been around a long time, but it’s only in recent years that our population has boomed — and it continues to grow at rates that leave little room for other species. Check out this time-lapsed map video, courtesy of Population Connection, to see what unsustainable population growth looks like and where we just might be headed.

Hellbenders Rock
Hellbenders aren’t exactly the cuddliest of species, but at 2 feet long, they’re North America’s largest amphibian. And they’re facing extinction from the effects of human population and pollution on freshwater streams. Happily for the hellbender, a band from St. Louis is now doing this salamander justice through song. We think there are few things more rockin' than raising a little hellbender.

The City of San Francisco vs. Lange’s Metalmark Butterfly
More than 100 years ago, the Lange’s metalmark butterfly nearly lost its home to rebuild San Francisco. The human population continues to grow in Northern California, but the Antioch Dunes National Wildlife Refuge is all the Lange’s metalmark butterfly has left.

Suburbia Moves Into Panther Territory
Florida is famous for its rapid development, and as its coast gets more crowded, more houses and roads are built inland, slicing through the habitat of the iconic Florida panther. While the state’s human population keeps doubling, these majestic large felines featured on one of our Endangered Species Condoms packages are being pushed to the brink of extinction.
