Climate Change Going green is about empowered citizens making choices in our daily lives that promote a healthy planet, from what you eat to what you wear, to how you get from here to there, to civic engagement in your community. Sustainability means supporting the environment and using natural resources responsibly, so future generations can enjoy our planet too. One of the key environmental issues of our time is our climate changing, which is connected to global carbon emissions. When we burn fossil fuels for energy, we add more and more carbon into the atmosphere. This buildup acts like a thickening blanket that traps heat more and more. The denser the blanket gets the more heat it traps underneath. This trapped heat is warming our average global temperature and disrupting the climate. Our climate system is changing in many ways around the world, impacting people, places, and animals. For example, the extra heat results in the loss of the amount of sea ice on the planet. It also leads to longer warm seasons – the ice breaks up earlier in the spring and forms later in the fall. These changes in climate drastically affect polar bears habitats and makes it harder to find food/build dens.
