America's overshoot is magnified by mass immigration
Immigration-driven population growth forces the U.S. to meet its consumption demand by taking resources from future generations (drawing down domestic resources), and from other countries (importing resources; exporting waste). This is what the scientific community calls "overshoot." We cannot sustain this level of immigration.
August 1st marks the date when humanity's demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. The United States hit its Overshoot Day this year on March 14.
