What is Plastic Free Ecochallenge?

Plastic Free Ecochallenge is a 31-day, global challenge in July to reduce and refuse single-use plastics. It’s a great way to take action on creating plastic-free habits. The environmental impact of plastic is significant, so reducing our reliance on single-use plastic is a win for wildlife!

What is EcoChallenge?

The Maryland Zoo is collaborating with other accredited zoos and aquariums across North America to make a positive impact on the planet! To do this, we are utilizing a platform called Ecochallenge. Through Ecochallenge, you get to build your own challenge, make your own rules, earn points and see how you stack up against other plastic-free warriors. Pledge to take as many or as little plastic-free actions as you want, and see our collective impact add up, in real-time.

For the last four years, the Maryland Zoo and volunteers participated in a Plastic Free Ecochallenge competition against other zoo and aquarium across the country and took home first place! We need your help to defend our title while conserving the environment.

The Bad News:
  • An estimated one million seabirds and 100,000 marine mammals and sea turtles die from plastics in their environment.
  • Recent research also suggests that terrestrial species are negatively affected as more microplastics make their way into their ecosystems.
  • Some of the animals you visit at the Maryland Zoo whose wild cousins are negatively impacted by plastic pollution are penguins, polar bears, pelicans, and river otters.
The Good News:
  • Over 181 million people visit AZA-accredited zoos and aquariums each year – that’s more attendance than major professional sporting events combined – so our community has the opportunity to make a big impact!
  • Did you know that common wisdom says it takes three weeks to change a habit? If you can stick with a new behavior for 21 days in a row, you’re a lot more likely to keep it up forever. After reducing your reliance on single-use plastic for a month, you may very well be a plastic-free warrior for life.
  • Last year, by changing our habits during the Plastic Free July Ecochallenge, our Ecochallenge team kept 3,337 pieces of plastic containers out of the landfill, picked up 3,197 pieces of litter, signed 239 petitions and more!
