Larger than life with a small ‘l’ – ant colonies and the big mind

Friday, March 19, 2010

I don’t know how this can be explained purely by the neo-Darwinian idea that the purpose of life is to propagate one’s genes. (Could such architecture be programmed within the genes of a single ant???)  And I don’t know how this can be explained without some notion of supra-organism intelligence or mind. Watch and wonder at our world -

- and consider the supra-human mind of which we must be a part. Might there be a dimension to Life with a capital ‘L’ that we forget in our ‘own’, individual lives?

Cities rot the brain: why we need nature

Extract from an article in the Boston Globe that mostly makes sense (except where the author seems to suggest nature is an ‘all calming’ influence; he needs to get out more!) -

While the human brain possesses incredible computational powers, it’s surprisingly easy to short-circuit: all it takes is a hectic city street.

“I think cities reveal how fragile some of our ‘higher’ mental functions actually are,” Kuo says. “We take these talents for granted, but they really need to be protected.”

Related research has demonstrated that increased “cognitive load” — like the mental demands of being in a city — makes people more likely to choose chocolate cake instead of fruit salad, or indulge in a unhealthy snack. This is the one-two punch of city life: It subverts our ability to resist temptation even as it surrounds us with it, from fast-food outlets to fancy clothing stores. The end result is too many calories and too much credit card debt.

City life can also lead to loss of emotional control. Kuo and her colleagues found less domestic violence in the apartments with views of greenery. These data build on earlier work that demonstrated how aspects of the urban environment, such as crowding and unpredictable noise, can also lead to increased levels of aggression. A tired brain, run down by the stimuli of city life, is more likely to lose its temper.

Long before scientists warned about depleted prefrontal cortices, philosophers and landscape architects were warning about the effects of the undiluted city, and looking for ways to integrate nature into modern life. Ralph Waldo Emerson advised people to “adopt the pace of nature,” while the landscape architect Frederick Law Olmsted sought to create vibrant urban parks, such as Central Park in New York and the Emerald Necklace in Boston, that allowed the masses to escape the maelstrom of urban life.

Although Olmsted took pains to design parks with a variety of habitats and botanical settings, most urban greenspaces are much less diverse. This is due in part to the “savannah hypothesis,” which argues that people prefer wide-open landscapes that resemble the African landscape in which we evolved. Over time, this hypothesis has led to a proliferation of expansive civic lawns, punctuated by a few trees and playing fields.

However, these savannah-like parks are actually the least beneficial for the brain. In a recent paper, Richard Fuller, an ecologist at the University of Queensland, demonstrated that the psychological benefits of green space are closely linked to the diversity of its plant life. When a city park has a larger variety of trees, subjects that spend time in the park score higher on various measures of psychological well-being, at least when compared with less biodiverse parks.

“We worry a lot about the effects of urbanization on other species,” Fuller says. “But we’re also affected by it. That’s why it’s so important to invest in the spaces that provide us with some relief.”

When a park is properly designed, it can improve the function of the brain within minutes. As the Berman study demonstrates, just looking at a natural scene can lead to higher scores on tests of attention and memory. While people have searched high and low for ways to improve cognitive performance, from doping themselves with Red Bull to redesigning the layout of offices, it appears that few of these treatments are as effective as simply taking a walk in a natural place.

Given the myriad mental problems that are exacerbated by city life, from an inability to pay attention to a lack of self-control, the question remains: Why do cities continue to grow? And why, even in the electronic age, do they endure as wellsprings of intellectual life?

Recent research by scientists at the Santa Fe Institute used a set of complex mathematical algorithms to demonstrate that the very same urban features that trigger lapses in attention and memory — the crowded streets, the crushing density of people — also correlate with measures of innovation, as strangers interact with one another in unpredictable ways. It is the “concentration of social interactions” that is largely responsible for urban creativity, according to the scientists. The density of 18th-century London may have triggered outbreaks of disease, but it also led to intellectual breakthroughs, just as the density of Cambridge — one of the densest cities in America — contributes to its success as a creative center. One corollary of this research is that less dense urban areas, like Phoenix, may, over time, generate less innovation.

The key, then, is to find ways to mitigate the psychological damage of the metropolis while still preserving its unique benefits. Kuo, for instance, describes herself as “not a nature person,” but has learned to seek out more natural settings: The woods have become a kind of medicine. As a result, she’s better able to cope with the stresses of city life, while still enjoying its many pleasures and benefits.

Five (make that six) reasons to hope

Friday, November 21, 2008

…that global warming is deflected:

1. Hope for the Rain Forests

California, as part of its effort to curtail global warming, could allow companies to pay for projects that preserve Brazilian and Indonesian rain forests, according to Bloomberg. The agreement was described as “pioneering” and goes a long way toward tackling the “other” cause of carbon emissions (other than burning fossil fuels) – destroying forests. Indonesia and Brazil are among the world’s top carbon polluters (No. 3 and No. 4, respectively, behind China and the United States) largely because their forests are disappearing so quickly. This agreement could help stop the 20% of global carbon emissions that come from deforestation.

Indonesia, meanwhile, plans to plant 100 million trees in 2009, according to Reuters. Indonesia has already lost 70% of its original forests, and loses enough forest every year to cover Connecticut and Rhode Island (and then some), but it still retains a forest about the size of Texas and Oklahoma combined.

2. Britain Goes All In

Britain became the first nation in the world to set binding limits on greenhouse gas emissions that match U.N. targets. The law requires the government to slash emissions 80% below 1990 levels by 2050, according to Agence-France Presse. Under the law, Britain will have to meet new carbon-reduction targets every five years.

3. Coal Is on the Defensive
For years, the norm in environmental litigation has been something like this:
– i. Polluting industry proposes polluting
– ii. Government agencies agree
– iii. Environmental groups sue
– iv. Courts side with environmentalists
Well, there’s a new chapter. In Kansas, where the Democratic Gov. (and one-time purported vice presidential possibility for Obama) Kathleen Sebelius stopped the construction of a coal plant because of the greenhouse gas emissions it would pump into the atmosphere, Sunflower Electric is taking her and her environmental agency to court. The company’s complaint? That its civil rights were violated by the governor’s decision.

4. The U.S. Can Cut Energy Use 20%

A new report lays out a framework for U.S. states to dramatically cut energy use — 20% by 2025. The proposed investments in energy efficiency would save $500 billion over 20 years, cut the need for new energy sources by 50% and reduce greenhouse gas emissions dramatically.

So who produced this report? Some radical left-wing conspiracy of economy-killing tree huggers? Nope. Try Bush Administration. The Department of Energy and The Environmental Protection Agency released the report, National Action Plan Vision for 2025: A Framework for Change.

“Change” … Now where have we heard that word recently …?

5. Obama

In a speech delivered via video to a bipartisan climate summit in California, Obama pledged to take strong action to combat global warming. Here’s what he had to say:


– those reasons from 19th November ’08.  There’s also the news from 20th November that an environmentally-progressive US Congressman has upended the formerly oil- and Detroit-friendly leadership of the influential Energy Committee. Which is good for Obama’s agenda, and better for the wider world.  Even if it does foster the end of the car-manufacturing machine as we know it.  Too bad.  So long and thanks for all the (dead) fish.

Mangrove Heart by Arthus-Bertrand by you.

- so said Yves Arthus-Bertrand.  He spotted this mangrove swamp in New Caledonia, Canada, from some flying machine and the naturally-occurring, heart-shaped clearing struck a chord.  He had undertaken his project, ‘Earth from Above’, to express the beauty of the planet and raise awareness about environmental and social issues.  The caption that came with this photo -

Swamps like the one here are crucial to protecting coastlines and cover almost a quarter of tropical coasts.  But that’s just half of what it was, having shrunk due to development and pollution.

He said,

‘We have to love, to share… there is no way we can have sustainable development in the world if we cannot live together’.

His goal is to get people to change their lives, leaving smaller footprints and a more sustainable future.

‘We want everything faster. We cut the trees faster than the trees grow. We take the fish faster than they can reproduce. We send CO2 into the sky faster than the CO2 can be absorbed. If we don’t change nature is going to force us to change … We are part of the ecosystem. We have forgotten, it’s not nature on one side and man on the other side. Man is part of nature.’

Sumptuous.

Awakening to our true place in the universe: on the need to cut light pollution

Monday, November 17, 2008

Flagstaff night sky / starry starry night by MichaelPgh.uploaded to flickr by MichaelPgh

The desire and ability to dispel darkness has been one of the blessings of modernity.  It has enabled us to extend our days and pursue our interests for longer.  However, such is the disquiet that only now are concerns about the unintended consequences of our lust for light being given an airing in the likes of National Geographic magazine. The ‘peripheral glow of our prosperity’ that is light pollution has been significantly screwing up the habits and dispositions of many of our creaturely neighbours. And we are only beginning to query what it might be doing for us -

Unlike astronomers, most of us may not need an undiminished view of the night sky for our work, but like most other creatures we do need darkness. Darkness is as essential to our biological welfare, to our internal clockwork, as light itself. The regular oscillation of waking and sleep in our lives—one of our circadian rhythms—is nothing less than a biological expression of the regular oscillation of light on Earth. So fundamental are these rhythms to our being that altering them is like altering gravity.

For the past century or so, we’ve been performing an open-ended experiment on ourselves, extending the day, shortening the night, and short-circuiting the human body’s sensitive response to light. The consequences of our bright new world are more readily perceptible in less adaptable creatures living in the peripheral glow of our prosperity. But for humans, too, light pollution may take a biological toll. At least one new study has suggested a direct correlation between higher rates of breast cancer in women and the nighttime brightness of their neighborhoods.

In the end, humans are no less trapped by light pollution than the frogs in a pond near a brightly lit highway. Living in a glare of our own making, we have cut ourselves off from our evolutionary and cultural patrimony—the light of the stars and the rhythms of day and night. In a very real sense, light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way—the edge of our galaxy—arching overhead.

I wrote about the need to cut light pollution, and to develop awareness of the starry sky, before.

Wall Street, you ain’t seen nothing yet: the real credit crunch

Wednesday, October 29, 2008

The financial credit crunch amounts to peanuts when compared with the situation on the ground -

the reckless consumption of “natural capital” is endangering the world’s future prosperity, with clear economic impacts including high costs for food, water and energy.

Some environmental economists have being doing some calculations -

the cost of natural decline dwarfs losses on the financial markets. [...] “So whereas Wall Street by various calculations has to date lost, within the financial sector, $1-$1.5 trillion, the reality is that at today’s rate we are losing natural capital at least between $2-$5 trillion every year.”

Nitrogen fluoride: the greenhouse gas 17,000 times more potent than CO2

Friday, October 24, 2008

is rising.  Between 2006 to 2008, it’s increased in the atmosphere from approximately 1200 to 5400 tonnes.  The cause?

[It] is one of several gases used during the manufacture of liquid crystal flat-panel displays

- that’s computer and tv screens to you and me. Even more disconcerting is that it’s also used in the manufacture of ‘thin-film photovoltaic cells’, i.e. solar panels.  Harrumph.

From livescience.

Consuming for the economy or the future?

Friday, October 24, 2008

Alastair McIntosh was contributing BBC Radio 4’s Thought for the Day yesterday.  Here’s an excerpt -

Our conundrum is that we need more consumption to save the economy, but less to save the planet.

Spending our way out of a recession is therefore only a stop-gap measure. It’s methadone for our planetary heroin addiction.

We simply feed the habit if we think that today’s problems can be tackled at conventional political, technical or economic levels. If we’re redefining our “central mission”, we must press further.

Technical fixes are certainly part of the solution. But I’d put it to you that the deep work must be this: to learn to live more abundantly with less, to rekindle community, and to serve fundamental human need instead of worshiping at the altars of greed.

The crisis of these times is therefore spiritual. It calls for reconnecting our inner lives with the outer world – an expansion of consciousness. And that’s an opportunity that we neglect at our peril, for as I once heard an old Quaker woman say, “It is perilous, to neglect one’s spiritual life.

Words from the wise on Palin – and Putin

Tuesday, October 7, 2008

So Sarah Palin the Republican Vice-Presidential Cadidate likes to hunt and shoot bears. And Putin, premier of Russia, released photos today of him having just killed a tiger. What’s to say? Apart from all the usual ethical stuff, I see them as cowards and bullies. Intelligent primates with modern guns will always win against animals. Take away their weapons and give them spears or axes. And then, if they win, make sure that every scrap of meat is eaten and every sinew and patch of hide used productively. And give prayers of gratitude. – Naively, I want these people to be more empathic and, as leaders, lead us into a more harmonious future.
