A few key facts from America's Environmental Report Card

- The United States, with less than 5% of the world's population, consumes 25% of the earth's energy resources, mostly fossil fuels.

- The amount of solid waste each American generated each day increased by 70% between 1960 and 2000, from 2.7 pounds per person to 4.5 pounds per person.

- Americans generate about twice the amount (of solid waste) per capita generated by other industrialized countries such as Germany, France, or Japan.
