Green Options

We’ve all done the elementary school math story problem: Would you rather have $10,000 right now, or a penny doubled every day for a month? Well, in the end, those of us who were greedy enough to take the $10,000 right up front ended up poorer than those who took the penny.

This problem seems silly to us though. Now what about this one. Would you rather take $1,000 right now or $4,000 three years from now? Chances are, you chose the immediate cash. Psychologists use the term ”delay discounting” to describe our inability to resist the temptation of a smaller immediate reward in lieu of receiving a larger reward later. Most people choose the smaller, more immediate reward over the larger “patience is a virtue” reward.

And no matter what the context, discounting stems from three factors: a bias for the present; uncertainty; and projected resources. We are a people who thrive on instant gratification; that’s one reason we love TV so much. It is also a contributing factor to the current economic crisis (and debt in general).

A far reaching report has called on the aviation industry to drastically increase the use of biofuels, to make a 60% reduction in its greenhouse gas emissions by 2050.

The study, called ‘Green Skies Thinking‘, was published today by right wing think-tank Policy Exchange, and advocates the phase-in of an EU Sustainable Bio-Jet Fuel Blending Mandate by 2020, which would force aviation companies to commit to a rising proportion of jet fuel from sustainable bio-jet fuels.

Crucially, the report also reckons that growing the feedstock needed for advanced biofuels would require significantly less land and be more sustainable than first generation biofuels such as bioethanol and biodiesel, generally used by road transport.

The first car my best friend ever drove was a early 80’s Honda Accord hatchback. It was little more than an oversized rollarskate with a tiny, 80 horsepower engine, but it beat the hell out of walking. The car itself was cramped and lacked all the amenities one would find standard on today’s cars, even cupholders. Today, the car serves as an immobile flower bed for a maple tree and wildflowers, but the memories will remain.

Flash forward to today, and a new study finds that since the early ’80’s the Honda Accord has packed on over 1,000 lbs, doubled its standard horsepower, and fuel economy has steadily dipped. The study seems to suggest that if vehicle weight, horsepower, and torque were held at their 1980’s levels, then fuel efficiency could have increased by at least 50%, rather than the 15% increase that actually occured. But is it really that simple?

Two seperate scientific studies have revealed that global warming is leading to significant reductions in the size of sheep and fish species, more evidence that climate change is forcing a huge range of species to adapt to a hotter world.

The first study, published in the Proceedings of the National Academy of Sciences, investigated fish populations in French rivers and the Baltic Sea and discovered that fish are shrinking as their habitats heat up.

Results show that average fish size in many French rivers have declined over the last thirty years, while the geographical range of tiddlers in the Baltic expanded as species such as herring and sprat also shrunk.

Male chimpanzees are able to exchange meat for sex with females, a recent study of wild chimps in Côte d’Ivoire found.

Notorious B.I.G.’s “more money more problems” way of thinking may not be true for male chimpanzees looking to mate. It turns out that male chimps who bring home the bacon–so to speak–have twice as much sex over the long term. This, despite meat making up only 1.4% of the diets of wild chimps.

Would you like a stroke with your cheeseburger? Scientists have found that your chances of having a stroke may actually be related to how many Burger Kings and KFCs are operating in your town. Researchers at the University of Michigan have found that the risk of stroke increases with the number of fast-food restaurants in a neighborhood. In the study, Texas residents with the highest number of fast-food restaurants had a 13 percent higher relative risk of suffering strokes than [...]

A groundbreaking study has proved that man-made light sources can change natural light cycles, triggering abnormal animal behavior that often leads to injury and even death.

The study, published in the journal Frontiers in Ecology and the Environment, confirms that polarized light pollution can cause confusion in creatures that rely on light ‘cues’ to navigate through their environment, with many animals also thrown off course by light reflecting from buildings.

A startling new WWF study has revealed that people living in Hong Kong currently use twice as many resources as residents in China, more than double the sustainable level.

To feed the vibrant city’s massive demand for natural resources, and absorb the CO2 emitted, residents need an area of land and sea larger than 250 Hong Kong’s, an incredible seven-fold increase since 1965.

According to Mathis Wackernagel, Executive Director of the Global Footprint Network, “Although small geographically, Hong Kong not only has significant resource demands, but it also has an over-proportional influence on the world.

Nasa scientists have told government’s that a simple cut in worldwide emissions of soot could lead to a dramatic reduction in the effects of global warming, as well as preventing hundreds of thousands of deaths from air pollution.

Soot contains black carbon, thought to be the second largest cause of global warming after carbon dioxide. Whilst airborne, it it spread around the globe by wind, heating the atmosphere by absorbing and releasing warmth from the sun’s rays. When it falls to the surface it also darkens snow and ice in polar regions or high mountain ranges, further reducing the Earth’s ability to reflect solar radiation.

Cutting soot emissions has a virtually instantaneous effect since it disappears rapidly from the earth’s atmosphere, unlike CO2, which can linger for hundreds of years.

A recent study published in the Journal of Physical Activity and Health found a strong correlational link between “active transportation” (defined as the percentage of trips taken by walking, bicycling, and public transit) and obesity rates in 17 industrialized nations. It appears that the more we sit on our butts and drive automobiles, the fatter we all become.

Officials in Ottawa are considering a cool plan to use the ‘cold energy’ stored in snow as a source of renewable energy in public buildings across the city.

Under the plan, snow collected on the Ottawa streets during the cold winter months would be used to keep the city’s hospitals, universities and government buildings cool during the hot summer. Snow collected during the winter normally melts by early June, but, if the plan gets the green light, it will be insulated with wood chips, making it last until September. The icy melt-water could then be fed through pipes to keep buildings cool without the need for expensive, and energy hungry, air conditioners.
