Study says the date by which we consume a year’s worth of resources is arriving faster

As a result, the Earth Overshoot Day – which marks the point at which consumption exceeds the capacity of nature to regenerate – has moved forward two days to 1 August, the earliest date ever recorded.
To maintain our current appetite for resources, we would need the equivalent of 1.7 Earths, according to Global Footprint Network, an international research organisation that makes an annual assessment of how far humankind is falling into ecological debt.

Thirty years ago, the overshoot was on 15 October. Twenty years ago, 30 September. Ten years ago, 15 August. There was a brief slowdown, but the pace has picked back up in the past two years. On current trends, next year could mark the first time, the planet’s budget is busted in July.
While ever greater food production, mineral extraction, forest clearance and fossil-fuel burning bring short-term (and unequally distributed) lifestyle gains, the long-term consequences are increasingly apparent in terms of soil erosion, water shortages and climate disruption.
The day of reckoning is moving nearer, according to Mathis Wackernagel, chief executive and co-founder of Global Footprint Network.

The situation is reversible. Research by the group indicates political action is far more effective than individual choices. It notes, for example, that replacing 50% of meat consumption with a vegetarian diet would push back the overshoot date by five days. Efficiency improvements in building and industry could make a difference of three weeks, and a 50% reduction of the carbon component of the footprint would give an extra three months of breathing space.

But the overall trend is of costs increasingly being paid by planetary support systems.
Separate scientific studies over the past year has revealed a third of land is now acutely degraded, while tropical forests have become a source rather than a sink of carbon. Scientists have also raised the alarm about increasingly erratic weather, particularly in the Arctic, and worrying declines in populations of bees and other insect pollinators, which are essential for crops.
