Design of the Svalbard seed vault as of early 2007

In 1992, the Global Biodiversity Convention (GBC) was adopted in Rio de Janeiro, and which placed the biodiversity issue center stage–calling for the world-wide preservation of biodiversity and its equitable and sustainable use. The convention was established in response to both the increasing rate of plant extinction (through habitat loss), fears by poorer nations of “biopiracy”, and the increasing agricultural use of land for high-value crops, to the exclusion of lesser-value ones–a practice that diminishes crop biodiversity. These lesser-value crops are typically grown by independent and small farms in less economically advanced countries. Many of these so-called “orphan crops” risk becoming extinct. Further, many species of plant or tree that fall outside the conventional definition of agriculture–such as the sea-water tolerant mangrove tree–are being ignored, to the possible peril of future agriculture.

Recent warming trends pose the greatest threat to preserving global “agrobiodiversity” due to its predicted alterations in temperature, precipitation, and sea level (thus the intrusion of saline water into fresh water ecosystems). Also, computer models show that global warming will increase the frequency and duration of flood and drought cycles. To protect civilization’s long-term food supply (and to protect against the social chaos of food shortages from consequent crop failures) from these potentially calamitous effects, scientists and agricultural policy experts, in cooperation with various governments, have begun establishing cryogenic gene banks to preserve the seeds of various, valuable crops for future agricultural use. The most notable example of this is the International Rice Research institute (IRRI) in the Philippines which stores over 100,000 strains of rice.

Puff is attached near the exhaust pipe of your vehicle. Its color changes dynamically, visualizing the amount of pollution your car is producing. Green indicates the lowest rate of pollution, red the highest.

Modern artists have often tackled environmental and ecological issues head on, such as through incorporating litter and refuse into sculptures, while other artists (such as photo, video and film artists) have sought to document industrial waste and/or have taken strong oppositional/advocacy stances in their works.

In recent years, many artists have sought to move beyond these “reactive”, commentary, and  documentary approaches and create objects and devices that serve practical purposes (if still a bit fanciful in appearance). One such artist/designer is Karolina Sobecka, whose car emissions monitoring device, ‘Puff’ , provides colorful feedback to the car owner on how “cleanly” (or efficiently) he/she is using/burning gasoline.

This author recently contacted Ms. Sobecka and asked her about this device (’Puff’) as well as her other designs, and her artistic/social/environmental goals.

Diatoms are one of the most common types of phytoplankton.

Climate change isn’t just warming the atmosphere, it’s also warming the ocean’s surface and deeper levels of the water column. This is known as the pelagic ocean (the “pelagic zone” is any part of the water column other than that at the sea floor) and it just so happens to harbor the most productive ecosystem on planet Earth. The pelagic ocean is responsible for an estimated half of the world’s primary production (i.e., the basic food or nutrient making needed to sustain other life), and sustains most of the world’s natural fisheries.

The pelagic zone also plays a very complex but important role in the global carbon cycle. Inorganic carbon (mostly in the form of CO2) can be “drawn down” from the atmosphere by two main processes: the respiration of photo-synthetic algae and plankton (which produce oxygen and serve as a food source as well), and, secondly, the sedimentation of carbon (in the form of sinking, dead marine matter) onto the sea floor. Most algae and phytoplankton have chlorophyll and live in the upper most layer of the water column where there is sufficient sunlight penetration (this is called the euphotic zone; from the surface down to 200 meters is the epipelagic zone). Although carbon is also removed via “outgassing” (the exporting of carbon and carbon-based molecules into the atmosphere via ocean-air circulation), these two processes keep carbon out of the atmosphere. And of the two, bottom accumulation (via sinking) is the predominant means by which carbon is removed from the water column.

Bacterial evolution can be accelerated with the MAGE technique to produce large numbers of  favorable mutations (micrograph image of E. coli bacteria magnified 10, 000 times)

Bacteria are prolific replicators, and some species can replicate into the millions in just a few hours. Bacteria, in the functioning of their cellular and biochemical machinery, also just happen to manufacture some very useful chemicals and bio-active molecules. The microbe populations also exhibit high rates of random mutation, which can confer adaptive traits, over time, onto the newer, variant population.

These attributes of bacterial life forms have been exploited in the biology lab (and in other industries) for some time, but generating genomic diversity in the lab has been challenging; inserting genes or entire genetic sequences into a cell’s nucleus (and DNA) can be done readily, but controlling or directing how exactly these hybrids mutate, is quite another thing. Further, new phenotypes (the main physical traits or properties) don’t usually happen fast or frequently enough for practical uses. But with a new technique called MAGE (Multiplex Automated Genome Engineering), bacteria are now being engineered (and “directed”) to perform these functions much faster and much more efficiently.

Foragers coming in loaded with pollen on the hive landing board.

In 2007, large commercial beekeepers started reporting big drop-offs in their bee colony populations. By 2008, estimated colony losses of between 30 and 70% were being reported, as a flurry of bad news about bees made the media rounds.

The loss since then of over 40% of the nation’s commercial honey bee (Apis mellifera) colonies–most seemingly due to so-called Colony Collapse Disorder (CCD; caused most likely by the IAPV virus)–ushered in predictions of dire consequences for valuable crops around the world due to a lack of pollinators.

But a recent analysis of global honey bee populations (by Aizen and Harder*) shows a 45% increase in total numbers since 1961. The data for this analysis came from a global database of managed honeybees. The same researchers note, however, that the global stock of honey bees is growing slower than the global demand for them–which comes primarily from the cultivation of “luxury” crops like fruits and nuts. The the year round demand for items like cherries, mangoes, almonds and pistachios is far out-pacing world-wide production, leading to the perception of a shortage of pollinators.

Bylot Ice Cap on Bylot Island, one of the Canadian Arctic Islands, August 14, 1975 (USGS)

The Arctic: Cooling No More.

A group of climatologists at Northern Arizona University are confirming that 2000 years ago, the Earth’s Arctic region had already entered a prolonged cooling phase. The phase continued up through the Middle Ages and on past the so-called Little Ice Age (1400 - 1800 C.E.). However, that all started to change (in the positive direction) between 1850 and 1900 C.E.–roughly in parallel with the onset and rise of the Industrial Revolution in the U.S. and Europe. And, by 1950, the warming trend had picked up in earnest.

The results of their 2000-year reconstruction of Arctic temperatures also showed clearly that four of the five warmest decades occurred in the period between 1950 and 2000. This buttresses the mounting evidence (such as that from the International Polar Year studies) of recent climate change and would suggest some newer mechanism at work impacting global temperatures.

It’s called the Pacific Intertropical Convergence Zone (PICZ) and its activity brings roughly 4 meters of rainfall per year to the Pacific equatorial region. Tropical rainfall patterns greatly impact the livelihoods of more than a billion people. Historically, this zone appears to shift in tandem with cooling and warming trends in more northern latitudes. And, it may be on the move again.

This possibility is born out in the results from a recent, oceanographic research project detailing the southward movement of this zone in the past (Southward movement of the Pacific intertropical convergence zone AD 1400–1850, Sachs et al, Dept. of Oceanography/Atmospheric Sciences, Univ. of Wash., June 2009, Nature GeoScience), but which also suggest that, in the present era, a potential, northward movement of this important, climate-impacting zone may be underway.

Pundamilia nyererei is a species of freshwater fish in the Cichlidae family. It is found in lakes in Kenya and Tanzania. It is becoming rare due to habitat loss.

In may not be a great surprise to learn that fish are the most species-rich vertebrate group on the Planet–with an estimated 32,500 member species. But what is surprising is that 43% of these species are found in freshwater habitats, such as lakes and rivers.

This rich diversity of freshwater species is all the more startling when one considers that freshwater systems represent just one hundredth of one percent (.01%) of the Earth’s surface water. According to Fishes of the World (J.S. Nelson), over 5000 new species of freshwater fish have been discovered in just the past three decades–a time period marked by expanded exploration of fish habitats and better understanding of “taxonomic boundaries” (mostly, due to more accurate genetic analysis).

The three summits of Mount Rainier: Liberty Cap, Columbia Crest,and Point Success (unaltered image)

Most of us would consider a trip to a state or national park to be a chance to get away from the pollution that plagues our cities. But it’s seldom easy to escape the effects of urban, industrial air pollution. Now, with a new art project called ECLIPSE, the web viewer or park visitor can see real time air quality data “imposed” on the otherwise scenic landscapes of our state and national parks.

ECLIPSE, based on an open source program, is the handiwork of artists Cary Peppermint and Leila Christine Nadir of EcoArtTech, and is a sponsored project of New Radio and Performing Arts, Inc. for its website turbulence.org.

So, how does it work? Just select a State/National park from a drop down menu, click the “apply AQI (air quality index) conditions” button, and ECLIPSE then performs two “data scraping” functions…if air quality data is available for that park, the program sorts through Flickr.com for images tagged with that particular park’s name, then, the program “corrupts” or alters the image to reflect air quality data (culled from the most recent AQI updates on the www.airnow.gov website) of the nearest, large city within a 65 mile radius.

The air quality rating system uses the following scale: good – fair – moderate – unhealthy – very unhealthy –hazardous*. The AQI rating is a measure of particulate matter in the atmosphere, based on a range of 0 – 500 parts per million, with “good” being 0 - 50 ppm, and “unhealthy” being 151 ppm or higher.

Airnow.gov maintains 300 monitoring stations in cities across the country. With the ECLIPSE program, the more pollution present in the atmosphere of the park’s nearest city, the more visually “corrupted” the image becomes. This alteration process utilizes various algorithms that affect color, saturation, and contrast, and, additionally, impose intermittent mirroring, deletion, or cropping functions on the image’s data file.

Air quality is determined by the presence of particulate matter in the lower atmosphere. Particulate matter is a complex mixture of moisture and small particles of dust, soot, soil, various acids (e.g., nitrogen or sulfur containing acids) and trace metals.

The artists’ website notes that, In 2008, the EPA’s own Clean Air Scientific Advisory Council (CASAC) protested that the EPA was not upholding its mission to protect air quality standards according to
the scale.

*Note that U.S. air quality ratings are different than Canada’s AQ rating system, for example. The U.S. system has more gradations of air quality in which “moderate” in the U.S. system is rated as “unhealthy”  on the Canadian scale. The site offers a visual comparison of air quality ratings between the US and Canadian indexes.

With the news that climate change is occurring at a faster rate than climate models have predicted, geoengineering solutions have been brought to the fore and are being taken more seriously. The main focus of these emergency geoengineering strategies is a reduction in “shortwave” radiation entering the Earth’s atmosphere via the solar wind.

The short-term goal here is an overall reduction in global atmospheric temperatures to slow, or even reverse, warming trends. These solutions include increasing the amount of reflective particles surrounding the Earth by placing reflective particles (”mirrors”) outside the atmosphere. Such a solution may be justified to quickly curtail an emergent crisis–such as the rapid disintegration of the polar icecaps. Another strategy is to blanket the upper atmosphere with sulfur particles to block shortwave energy from reaching the Earth’s surface, thus producing a pronounced cooling effect (of variable duration).

However, in a recently published paper, Climate Engineering Responses to Climate Emergencies by Blackstock et al, this and other controversial strategies are analyzed in terms of feasibility, short-term impact, and also, the potential risks and dangers. The authors are also calling for a study phase. The major criticism in the paper is that current geoengineering strategies focus on a reduction of temperature without due consideration of the impact on precipitation, which also drives climate change. The cooler the surface temperature, in general, the less overall precipitation ( due to the fact that there is less energy for evaporation). Focusing only on temperature reduction, via incoming solar radiation, could backfire, leading to a shift in global hydrology cycles and, possibly, drought. Also, sulfur in the atmosphere combines with water to form sulfuric acid–the primary source of “acid rain”–a problem dramatically reduced since the passage of the Clean Air act.

Phobos– the largest and innermost moon of Mars. Note the large crater shown in the lower right, known as ‘Sickney’.

The proposed experiment is called LIFE -Living Interplanetary Flight Experiment–and will be placed aboard Phobos-Grunt, a joint Russian-American mission to Phobos, the largest (and innermost) of Mars’s two moons (the smaller being Deimos). If all goes according to plan, it will be the first time living creatures from Earth will be sent intentionally beyond our Earth - Moon system.

The samples to be sent include four species of bacteria: Deinococcus radiodurans (a radiation resistant bacterium), along with three species of Archea (ancient, bacterial, life forms also known as “extremophiles” due to their ability to thrive in ultra-harsh conditions), several tardigrades (”water bears” - tiny, eight-limbed invertebrates known for their ability to repair their DNA), numerous yeast spores, seeds from the mouse-eared, cress plant Arabidopsis thaliana, and a soil sample from Israel’s Negev desert.

In a first, researchers at the University of Washington in Seattle have developed a completely tree-powered electrical circuit.

The nano-scale device—approximately 130 nanometers [a nanometer is one billionth of a meter] in size—consumes just 10 billionths of a watt (10 nanowatts).

Unlike the legendary science fair experiment in which a potato-based electric circuit is created using two electrodes (each electrode being a different metal, which react with the starch, causing a potential difference and thus a current), the UW device utilizes electrodes comprised of the same metal, and is able to generate (output) 1.1 volts. “As far as we know, this is the first peer-reviewed paper of someone powering something entirely by sticking electrodes into a tree,” according to paper co-author Babak Parviz, associate professor of electrical engineering at the UW.

Charles Darwin, 1879

In this the 150th anniversary year of the publication of Darwin’s On the Origin of Species (and the 200th anniversary year of his birth), it is worth returning to that era of profound discovery and re-examining some of the controversies and earlier evolutionary theories begotten in the years just preceding its publication.

Today (and ever since Origin), the core, controversial idea of evolution tends to be rather simplistically summed up as: “We are descended from apes”. Of course, Darwinism, as it came to be called, was far more than this simplistic distillation. Even still, Darwin’s description of evolution as “descent with modification”, as well as his positing of vast geologic time scales, the agencies of natural and sexual selection, and a common ancestry to all living creatures, were not the fundamental, conceptual causes of the controversies.

Brown cloud near Pune, India

The legendary glaciers of the Himalayan and Hindu Kush mountain ranges have been losing volume at an increasing rate over the past twenty to thirty years. And over this same time period, much data has piled up confirming the role of increased CO2 emissions in global warming trends. Given this, it would be “natural” to assume that CO2-induced warming was also to blame for the glacial melting. But it turns out that much stronger evidence points to the impact of “brown cloud” events.

There have been other extensive brown cloud events elsewhere, such as in Central and Eastern China (which first made headlines back in 2005). They can be several miles wide / long, and extend hundreds of meters or more high. The clouds would be more aptly described as massive, moving blankets of thick haze (similar to smog). They typically last anywhere from a few days to a week before they dissipate. The clouds are indeed lethal to some (asthmatics, elderly, young children, those with bad hearts) and have also been known to suffocate livestock.

John Willoner’s Eco-House at Findhorn (UK). Turf roof, passive solar, solar panel.

“Is it possible to affect the environment?”

That was one of the questions that confronted me on one on-line questionnaire I took over a year ago.

As a naturalist and former instructor of natural science and ecology (grades 1 – 9), I found this questions to be the most provocative of all. My initial response took the form of another question: How do you mean–positively or negatively? From the radical environmental perspective, all we can do is have a negative impact on the ecology/biosphere–just by existing as we do.

Both economic theory and experimental data concur–increasing the distance traveled to find food incurs “negative fitness consequences”, by decreasing total energy for maintenance, repair and reproduction. Yet, most animals must travel to find food. Individual, small groups, and large herds of eutherian (placental) mammals–like wild buffalo, gazelles, lions, and elephants–often travel great distances to find food. This expenditure of energy, at the apparent risk of biological fitness, has puzzled zoologists for some time.

As climate scientists scour the Earth’s surface looking for indications of climate change impacts, freshwater lakes and reservoirs are becoming the sentinels of choice for many investigations. Although they make up a small percentage of the planet’s surface area, such bodies of water–small to large–are providing clues to past climate fluctuations, as their sediments and “catchments” (the total chemical and biological material that results from the presence of the body of water) often record ancient climate shifts and impacts and offer indicators of current climate change.

World Fertility Rate Map

The current world population is approximately 6.5 billion people and growing. By or before 2050, that number will grow by almost 50% to 9 billion. With the availability of birth control and better education rates for women being higher in developed (industrial or post-industrial) nations, most of this increase is projected to come from the developing  world–those nations that are just now making significant progress away from exclusively agrarian societies, and towards full industrialization.

And despite the prevalence of fatal diseases, civil wars, and high infant mortality rates (note: the US has the highest infant mortality rate of any developed country), most of these developing countries continue to show population increases–especially as more effective medicines and health education (via government and private sector programs) become available.

It was called the “red mark test”, or just the “mark test”, and it was first tried out on a Gorilla over two decades ago. Scientists applied a smudge of red powder to the forehead of a sleeping gorilla, then placed a large viewing mirror close by, and waited for the ape to awaken. To the surprise of all, after the gorilla first noticed its reflection (and reacted to it as a social response), it then began to recognize that it was looking at itself, somehow, and, noticing the smudge over its eyes, immediately began trying to wipe it off. Later, the gorilla would use the mirror to groom itself and even examine parts of its body.

The test is now referred to as mirror self recognition (MSR). The test indicates self-awareness of a higher, and formerly, distinctly human level. The test is also thought to correlate to higher brain behaviors such as empathy and altruism.
