Earth hits 'Overshoot Day', NGOs raise alarm

This Thursday, mankind marks a dubious milestone: the day by which humanity has consumed all that the Earth can sustainably produce for this year, with NGOs warning that the rest of 2022 will be lived in resource-deficit. The date— dubbed as 'Earth Overshoot Day'— marks a tipping point when people have used up "all that ecosystems can regenerate in one year", according to the Global Footprint Network and the WWF.

"From January 1 to July 28, humanity has used as much from nature as the planet can renew in an entire year. That's why July 28 is Earth Overshoot Day," said Mathis Wackernagel, president of the Global Footprint Network.

"The Earth has a lot of stock, so we can deplete Earth for some time but we cannot overuse it forever. It's like with money; we can spend more than we earn for some time until we're broke," he added.

It would take 1.75 Earths to provide for the today's world population in a sustainable way, according to this measure created by researchers in the early 1990s. The Global Footprint Network said that this year, Earth Overshoot Day has arrived sooner than in the last 50 years. In 2020, the date moved back three weeks due to the Covid-19 pandemic, before returning to pre-pandemic levels. The burden is not evenly spread. If everyone lived like an American, the date would have fallen even earlier, on March 13, Wackernagel said.

The two NGOs point the blame at the food production system and its "considerable" ecological footprint.

"In total, more than half of the planet's biocapacity (55 per cent) is used to feed humanity," the two NGOs said.

"A large part of the food and raw materials are used to feed animals" that are "consumed afterwards", said Pierre Cannet of WWF France.

In the EU, "63 per cent of arable land" is directly associated with "animal production", he said.

"Agriculture contributes to deforestation, climate change by emitting greenhouse gases, loss of biodiversity and degradation of ecosystems, while using a significant share of fresh water," the NGOs added.

Based on scientific advice, they advocate reducing meat consumption in rich countries:
