Colorado's natural beauty is one of its strongest calling cards, and we must protect our environment to keep it that way. Our open wilderness areas provide habitat for a tremendous diversity of plant and animal species, and they draw out-of-state visitors who hike, bike, fish, hunt, ski and/or raft in Colorado. We might not have all the answers yet on how climate change could damage our environment, but we've seen studies suggesting that it could impact our already limited supply of water. Many Coloradans hold strong commitments to environmentalism, but work remains to be done when it comes to protecting air and water quality in certain parts of our state. Last but not least, our environment is an economic issue, since many Coloradans work in our numerous businesses that rely on our great outdoors - in industries such as tourism, outdoor gear retail or manufacturing, and providing supplies or services at popular tourist destinations.
