Humanity Set to Bust Our Yearly Ecological Budget on Aug. 1

Popular

Earth Overshoot Day—a marker of when the world's 7.6 billion people will "use more from nature than our planet can renew in the entire year"—will fall on Aug. 1, the earliest date yet since we first went into ecological debt in the 1970s.

"In other words, humanity is currently using nature 1.7 times faster than our planet's ecosystems can regenerate—or 'using 1.7 Earths,'" said the Global Footprint Network in a press release.


The international research organization uses Ecological Footprint accounting to calculate the date each year. Last year's Earth Overshoot Day fell a day later on Aug. 2.

"As we mark Earth Overshoot Day, today may seem no different from yesterday—you still have the same food in your refrigerator," Global Footprint Network CEO Mathis Wackernagel said in the press release. "But fires are raging in the Western United States and in Cape Town, South Africa, residents have had to slash water consumption in half since 2015. These are consequences of busting the ecological budget of our one and only planet."

So what will happen after Aug. 1? In the remaining five months of 2018, human beings will draw on Earth's precious and limited reserves of fresh water, land, fisheries and forests, making it harder for these ecosystems to regenerate their resources.

"Our economies are running a Ponzi scheme with our planet. We are using the Earth's future resources to operate in the present and digging ourselves deeper into ecological debt," Wackernagel said.

Compared to the 1960s, humankind only spent three-quarters of Earth's annual resource allotment. However, by the 1970s, economic and population growth has driven Earth into this annual downward trend.

Carbon emissions from the burning of fossil fuels has become the fastest-growing part of the Ecological Footprint, the Global Footprint Network warned. CO2 is also being released at a rate much faster than it can be absorbed.

Thus, a significant reduction of carbon emissions is "an essential step" to avoid ecological overshoot and to also mitigate the harmful impacts of climate change, the research organization stated.

"It's time to leverage our creativity and ingenuity to create a prosperous future free of fossil fuels and planetary destruction," Wackernagel said.

The Global Footprint Network has listed the four following solution areas to address ecological overshoot:

  • Cities: If we reduce driving by 50 percent around the world and replace one-third of car miles with public transportation and the rest by walking and biking, we can #MoveTheDate of Overshoot Day back 12 days.
  • Energy: Reducing the carbon component of humanity's Ecological Footprint by 50 percent would #MoveTheDate 93 days.
  • Food: If everyone in the world cut food waste in half, reduced the Footprint intensity of their diets, and consumed world-average calories, we would #MoveTheDate 38 days.
  • Population: If every other family in the world had one less child, we would move Overshoot Day 30 days by 2050.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.

The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.

Ocean scientists have been busy creating a global network to understand and measure changes in ocean life. The system will aggregate data from the oceans, climate and human activity to better inform sustainable marine management practices.

EcoWatch sat down with some of the scientists spearheading the collaboration to learn more.
