Today is the day on which we've used up our annual allowance for the Earth's resources – with four months to go until we should have done.
The 2nd August is this year's Earth Overshoot Day: when the amount of water, soil, and clean air that our planet can regenerate is spent before the year is up. This year, it falls a day earlier than it did in 2016. As a result, we'll be living on 'credit' until the New Year.
The day is calculated by the Global Footprint Network, a science of sustainability organisation. This is done by dividing the planet's biocapacity – the amount of ecological resource that it can generate that year – by our ecological footprint – our demand for the year, and multiplying that by 365, the number of days in the year.
"Our planet is finite, but human possibilities are not. Living within the means of one planet is technologically possible, financially beneficial, and our only chance for a prosperous future," said Mathis Wackernagel, CEO of Global Footprint Network and co-creator of the Ecological Footprint.
"We hope our new Footprint Calculator enables millions more people around the world to explore sustainability solutions and gain an uplifting sense of the possibilities available to society."
