BRENT: It is only August and humanity has already used a year’s worth of natural resources. According to the Global Footprint Network, August 13th 2015 was marked as “Earth Overshoot Day”, which is the date our consumption outgrows Earth’s natural resources.
“In less than eight months, humanity has used up nature’s budget for the entire year, with carbon sequestration making up more than half of the demand on nature, according to data from Global Footprint Network, an international sustainability think tank with offices in North America, Europe and Asia,” said the report.
Global Footprint Network, founded in 2003, measures humanity’s demand on the planet in comparison to nature’s ability to provide for the demand. The Earth Overshoot Day determines the date when humanity’s annual demand on natural resources exceed what Earth can provide in that year.
To determine the exact day, researchers calculate the number of productive biological across all around the globe. This areas absorb the damaging actions done by humans to the environment, such as the release of greenhouse gases into the atmosphere. The experts then estimated the amount of land that humanity would need to make up for the harmful actions. The result is Earth Overshoot Day which is the day when human demand exceed the planet’s ability to absorb it.
