This is a day earlier than in 2016.
When viewed over the longer-term-Earth Overshoot Day has been marked annually since 1983-the acceleration becomes even more glaring. "Rather, it is about whether their products and services are contributing to humanity getting closer to prosperity within the ecological means of one planet".
Deforestation, drought, fresh-water scarcity, soil erosion, biodiversity loss and the buildup of carbon dioxide in the atmosphere all can be identified as costs of that global ecological overspending.
In working out a person's Ecological Footprint, the calculator takes into account what they eat, where their food comes from, where they live, energy efficiency of their household, their transport and how much rubbish they produce compared to their neighbours, and how much productive surface area is required to meet all of their needs.
The app allows users to play with options, learn about solutions, and connect to brief facts about sustainability.
Food consumption is by far the biggest factor in overusing the planet's resources, with it making up 26 per cent of the global footprint. "Living within the means of one planet is technologically possible, financially beneficial, and our only chance for a prosperous future", Wackernagel optimistically said about the 2017 report.
Now only a beta version and available in English, the Global Footprint Network hopes to make future iterations of the calculator country-specific, multi-lingual and more fun. The carbon footprint makes up 60 percent of humanity's Ecological Footprint.
Eating less meat, burning less fuel, and cutting back on food waste are all effective methods of reducing the rapid consumption of vital resources, according to the report. If carbon emissions were cut in half, the date of Earth Overshoot Day would be pushed back by 89 days, or about three months.
Pledges include trying a new vegetarian recipe, donate money or switch to cycling. "However, the deal suffered a huge blow in June when Trump announced his plans to withdraw from the agreement".
On the supply side, Global Footprint Network tracks resource capacity (including cropland, grazing land, forest land, fishing grounds and built-up land) of more than 200 countries and regions from 1961 to the present.
