Global Climate Change

"The Earth's climate is changing. In most places, average temperatures are rising. Scientists have observed a warming trend beginning around the late 1800s. The most rapid warming has occurred in recent decades. Most of this warming is very likely the result of human activities.

Climate change can have broad effects on biodiversity (the numbers and variety of plant and animal species in a particular location). Although species have adapted to environmental change for millions of years, a quickly changing climate could require adaptation on larger and faster scales than in the past. Those species that cannot adapt are at risk of extinction. Even the loss of a single species can have cascading effects because organisms are connected through food webs and other interactions." - United States Environmental Protection Agency

We can all do our part to reduce our impact on global warming. Point Defiance Zoo & Aquarium is proud to be an Arctic Ambassador Center. These approved organizations provide leadership for carbon emission reduction in the communities, support Polar Bears International (PBI) research projects to help conserve wild polar bears, and play a key role in the PBI Sustainability Alliance, a front-line team helping to save polar bears in a rapidly warming Arctic.

What You Can Do

 Polar Bears International has a list of Actions with Impact that can help you get started.

Find out what you're already doing and challenge yourself to add two or three new ones. Before you know it, these new actions will become habits and you will be doing things every day to help polar bears and other wildlife!
