Just when you think all human activities are making the environment worse, news comes that our efforts to improve efficiency and reduce environmental impacts (0ur environmental footprint) are doing some good. According to a new U.S. Geological Survey report, the U.S. is using less water now than during the peak years of 1975 and 1980, despite a 30 percent population increase during the same time period.
The report shows that in 2005 Americans used 410 billion gallons per day, slightly less than in 2000. The declines are attributed to the increased use of more efficient irrigation systems and alternative technologies at power plants. Water withdrawals for public supply have increased steadily since 1950 — when USGS began the series of five-year trend reports — along with the population that depends on these supplies.
