The map below displays the American impact on the environment through consumption of natural resources as measured by the ecological footprint for each state. States are scaled to represent their total consumption of resources, which is dependent upon both population and average use patterns. States are colored on a logarithm scale to represent how much of the state's native resource production this consumption appropriates. Redder states consume more than they produce, whereas bluer states are living within their means; hover over a region for exact figures. As a whole, the United States consumed 1.8× the natural resources available within its borders in 2010.
