Earth's resources are not inexhaustible. Scientists calculated humanity's annual natural resource quota and discovered that this year, on August 2nd, we exhausted it entirely. From that day forward, we've been overdrawing on Earth's resources. Therefore, this day has been designated Earth Overshoot Day (also known as "Ecological Debt Day").
Earth Load Day: After this day, the ecological system will be overdrawn
Researchers devised this ecological assessment method in the early 1990s. The Global Footprint Network, citing United Nations data, calculated that feeding the world's population would require the resources of 1.7 Earths. As humanity's resource consumption accelerates, the date of overdraft approaches, leading to the concept of Earth's End.
Compared to last year, this year's overshoot day was delayed by five days, indicating a slowdown in humanity's resource consumption. However, the latest National Footprint and Biocapacity Accounts report notes that four of the days' difference is due to a methodological adjustment, meaning the improvement this year is only one day.
The Earth's rate of overcharging has slowed over the past five years, but experts are unsure whether this is due to the economic downturn or global efforts to reduce carbon emissions.
Which countries are depleting their resources the fastest? If we all lived in Qatar, we would run out of natural resources in 41 days (February 10), followed by Luxembourg (February 14), Canada, the United Arab Emirates, and the United States (March 13). The latest would be the African nation of Benin (December 26).
The rate at which people reduce their consumption of the earth's resources is still too slow
The Global Footprint Network points out that humanity's progress in reducing its use of Earth's resources is still too slow. Earth Overshoot Day will need to be delayed by 19 days each year for the next seven years to meet the UN target of a 43% reduction in carbon emissions by 2030 compared to 2010 levels.
Steven Tebbe, CEO of the Global Footprint Network, expressed concern that if ecological overshoot continues, it will lead to more extreme heat waves, forest fires, droughts, and floods, and threaten global food production. He further pointed out that cities, countries, and businesses should all strengthen resource security, which will not only help long-term development but also benefit the planet.
The Global Footprint Network points out that sufficient solutions exist to reverse overshoot. For example, increasing the share of low-carbon electricity from 39% to 75% would delay Global Overshoot Day by 26 days; halving food waste would add 13 days; and promoting tree intercropping (a type of agroforestry) would delay it by 2.1 days.
