The state of Colorado is projected to gain 1.8 million more residents by the year 2050. While that can be a sign of economic prosperity, a study by NumbersUSA indicates most residents think that growth will have too many negative impacts. … The study includes a scientific survey of 1,024 Colorado residents conducted by the Rasmussen research group. It focuses on several environmental issues, including water. Citing increased traffic, the loss of open space, and a strain on the water supply, 75% of Coloradans surveyed said urban sprawl, which is the encroachment of cities into natural space and agricultural space, is making Colorado a worse place to live.
