Overshoot: 'Humanity falls deeper into ecological debt'

Humankind will slip next week into ecological debt, having gobbled up in less then nine months more natural resources than the planet can replenish in a year, researchers said Tuesday.

The most dominant species in Earth’s history, in other words, is living beyond the planet’s threshold of sustainability, trashing the house it lives in.

At its current pace of consumption humankind will need, by 2030, a second globe to satisfy its voracious appetites and absorb all its waste, the report calculated.

Earth’s seven billion denizens — nine billion by mid-century — are using more water, cutting down more forests and eating more fish than Nature can replace, it said.

At the same time, we are disgorging more CO2, pollutants and chemical fertilizers than the atmosphere, soil and oceans can soak up without severely disrupting the ecosystems that have made our planet such a comfortable place for homo sapiens to live.

Counting down from January 1, the date when human activity exceeds its budget — dubbed “Earth Overshoot Day” — had receded by about three days each year since 2001.

The tipping point into non-sustainability happened sometime in the 1970s, said the Oakland, California-based Global Footprint Network, which issued the report.

This year, researchers estimate that the equivalent of Earth’s resource quota will be depleted on September 27.

“Overshoot” is driven by three factors: how much we consume, the global population, and how much Nature can produce.

The United States is the biggest ecological deficit spender, according to an earlier calculation by the same group.

If all people adopted the American lifestyle — big house, two cars, huge per-capita energy consumption — the world’s population would need about five “Earths” to meet its needs.

By contrast, if everyone on Earth matched the average footprint of someone in India today, humanity would be using less than half the planet’s biocapacity.

''Vertical street' collects rainwater'

From New Scientist:

The world’s first “vertical street” will soon be built in Melbourne, Australia.

Every sixth floor of the 35-storey building will have gardens capable of growing trees up to 10 metres tall and the entire building will be boasting the very latest in green technology.

While roof gardens and landscaped balconies have been constructed in the past, project architect Robert Caulfield of CK Designworks, Melbourne, says this is the first time that five high-rise communal gardens have been attempted in the same building.

To achieve this feat, purpose-built planter boxes allowing tree roots to grow in the confined 120-square-metre gardens, and structural supports that hold the weight of the soil and trees will be used. Heat-reflective glass and solar-powered lighting will also be incorporated.

Since the site is a mere 360 square metres, the building’s external walls - more than 8000 square metres - will be used to catch rainwater. “This is unusual,” says Caulfield. Normally strong winds “just blow the rain off the building”.

But, in this development, triangular balconies and a jagged façade are used to reduce the sideways movement of the wind, minimising the water escaping from the side. The catchment will feed into the building’s water supply to be used for garden watering and toilet flushing.

"It is by now an old idea in futurology, originating with Alvin Toffler, that modern man exists in a state of constant shock at the changing landscape of the technological world — akin to “culture shock,” but as ceaseless as the progress of technology. But we quickly become accustomed to, and adjust ourselves to, the technologies that increasingly form the fabric of our interaction with the world — and so their novelty rapidly fades. And then we find our experience of moving through the world is not one of perpetual awe and wonderment, but of boredom and restlessness."
