Easy Ways to Make an Impact

How to Choose Sustainable Seafood

Less than 15% of the world’s fisheries are considered sustainable—resulting in nearly 1,100 endangered fish species, according to the International Union for Conservation of Nature. Choosing sustainably farmed fish helps reduce the pressure on wild fisheries and allows populations to rebuild. To learn more about which sustainable seafood choices are best for you, visit  SeafoodWatch.org—a service of our AZA partner, Monterey Bay Aquarium.

Use Only What You Need.

Conserving energy and water reduces greenhouse gas emissions and can help reduce the effects of climate change—ultimately protecting endangered species. Here are simple ways to make a difference:

  • Follow lawn watering guidelines, purchase water-saving appliances, fix leaking sinks and toilets and take the shortest possible shower.
  • Change your furnace filter, put caulking around windows and install an automatic thermostat at energy-efficient set points.
  • Install energy-efficient appliances or bulbs, and find other resources to help save energy—and money!
  • Bike, carpool or walk whenever possible. Use My Way to Go to find a better commute!

Get Inspired. Inspire Others.

During your visit, listen and learn as much as you can about how to help protect endangered species—then teach your family and friends. Here are a few ways to get inspired:

  • Attend our daily animal demonstrations and keeper talks.
  • Book a spot in one of our Intimate Up-Close Look experiences.
  • Sign up for one of our transformative education programs.
  • Connect with our dedicated staff and volunteers—we love it!

Reduce. Reuse. Recycle.

Protect endangered species by preserving their natural habitats and keeping harmful pollutants and toxins out of the environment. It saves you money, too! Learn other ways Denver Zoo protects the environment and our community through our sustainability programs.

Shop Smart to Help Save Animals

As a zoo-based conservation organization, Denver Zoo is dedicated to giving our guests the information they need to make choices that support a healthy planet. That’s why we’ve partnered with Palm Done Right® to spread the word about palm oil and its impact on wildlife habitat.

Palm Oil | Sloth
Palm Oil | IceCream



While not all products within these categories will contain palm oil, their labels are worth a second look: bread, crackers, soap/detergent, ice cream, shampoo, chocolate, makeup, cooking oil, dairy substitutes and margarine.

Palm | Labels



When you're perusing product labels and nutrition facts, the word "palm" is a safe bet that the product contains palm oil. Also look for the prefixes STEAR, LAUR and GLYC, as these also indicate the presence of palm oil.



Looking for companies who use palm-positive practices? Our partner Palm Done Right can help you make smart choices—and select products with lower impact on vulnerable wildlife and ecosystems.


Become a Denver Zoo volunteer to inspire our guests to help save wildlife, or volunteer for one of our local conservation efforts, like the Colorado Pika Project*. You’ll conduct valuable research that will be used to help threatened alpine ecosystems and species.
