Scientists in South Africa are testing a genetically engineered tobacco plant which detects the presence of nitrogen-dioxide, a marker for landmines, to turn red, in the hope that it may eventually be used to clear mine fields in post-conflict zones around the globe.

The team is part of a joint initiative of University of Stellenbosch and the Danish biotechnology firm, Aresa, which has developed the “RedDetect” bio-sensor technology in a weed called Thales Cress.

The weed changes color from green to autumnal red when it detects nitrogen dioxide leaching from mines buried in the soil.

Because the weed is too small to be seen from a safe distance, the scientists went looking for a more viable alternative, and landed on the tobacco plant, which grows easily in most parts of the world, with a little help from genetic engineering.

This past Wednesday here in Australia saw the presentation of the National Bicycling Achievement Awards, as well as the presentation of a report entitled “Cycling: Getting Australia Moving,” compiled by Rob Moodie, Professor of Global Health, Nossal Institute for Global Health.

The key note speaker for the event, Moodie showcased the results of his study (pdf) which, amongst other things, saw that cycling currently saves an estimated $227.2 million per year in health costs alone. Dr. Moodie sayd that “this report demonstrates the considerable benefit offered to individuals and governments by cycling. Addressing the barriers preventing more Australians from cycling will deliver substantial savings to both government and the community”.

There is no consensus among water analysts on whether there will be global wars over water ownership.

According to UNESCO, globally there are 262 international river basins: 59 in Africa, 52 in Asia, 73 in Europe, 61 in Latin America and the Caribbean and 17 in North America — overall, 145 countries have territories that include at least one shared river basin.

UNESCO states that between 1948 and 1999, there have been 1,831 “international interactions” recorded, including 507 conflicts, 96 neutral or non-significant events and, most importantly, 1,228 instances of cooperation around water-related issues.

As a result, some experts argue that the idea of water wars is rather farfetched given the precedent of water cooperation that has been exhibited by many of the countries around the world.

“Despite the potential problem, history has demonstrated that cooperation, rather than conflict, is likely in shared basins,” says UNESCO.

You could be excused for thinking that Australia is on top of its environmental problems based on the amount of talk that business directs towards the issue. But our regulator’s recent swoop on tyre-manufacturer Goodyear’s inflated sales pitch shows that as green issues become mainstream, you have to be more wary of manufactures’ claims, not less.

It would be nice to think that as the world collectively wakes up to its immense environmental challenge that business could be relied on to direct its muscle and intelligence towards addressing these problems, authentically.

A report released by the Australian Bureau of Meteorology and the Commonwealth Scientific and Industrial Research Organization, has showcased facts that suggest Australia will suffer more extreme temperatures in the years to come, thanks all to climate change.

The report forecasted heat waves, less rain and a subsequent increased drought. It predicted that exceptionally hot years, which had originally only occurred every 20 to 25 years, were now more likely to hit every one or two years. And the report noted that all of this could start as soon as 2010.

For those who fervently follow global warming to the secret labyrinths of the White House, we all know what the professional spinners did with that email attachment from the Environmental Protection Agency about how greenhouse gasses were polluting the environment and should be checked.

Instead of acting upon it or even printing copies to president George Bush and his handlers, they tossed it in a cyber trash bin called Spam folder as if that was the only green thing to do.

Many months after Scott McClellan quit spinning for Dubya, climate watchers are crying foul that he never ever touched the seemingly hot subject in his recently released book, What Happened. But in his famous spins, he had blamed human activity - you and me - as responsible for global warming on more than one occasion.

Spin can be clever tomfoolery sometimes but the White House stance on global warming is well known and George W. Bush has never disappointed with his public statements that smack verily of official ignorance or pretense on the subject as an inconvenient truth.

On Friday, the International Whaling Commission’s annual meeting came to a close with a whimper. This year’s gathering was held in Chile, and the meeting’s chairperson, United States delegate William Hogarth, made a gutsy and stupid decision. Hogarth wanted to avoid confrontations at this year’s meeting, with the hope of creating good will among countries. He pontificated that this good will could be used to find solutions in the future (not now). Translation: he pleaded for member countries not to vote on or discuss important issues that concern whales. Based on what happened (or more accurately, did not happen), the meeting was very unsuccessful.

Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they’ve created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a conventional internal combustion engine of the same horsepower. Oh yeah, did I mention that it doubles the fuel economy too.

What that means is a car like the 2007 Toyota Yaris, which is rated at 40 mpg on the highway, would get 80 mpg with a Revetec engine.

This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims.

Adventures in the development of truly biodegradable plastics are showing that technology can help us with our environmental challenges, but make no mistake technology on its own will not be able to deliver us from our environmental quagmire. This will only happen when we are mature enough and motivated enough to make positive and voluntary behavioral change.

Some members of the Australian community went into paroxysm when our muddle-headed environment minister toyed with the idea of charging a modest fee for plastic disposable shopping bags that are ordinarily handed out free.

The plastic charge

Being and free and plastic is of course a lethal cocktail as far as nature is concerned. There are roughly 6 billion plastic bags used each year in Australia and this end up clogging up land fill sites or stuck in the throats of hapless aquatic life form, normally the very endangered.

Those against the move argued that people would struggle to get their shopping home, and that a large percentage of the replacement bags that customers used would be made of plastic anyway. It was also argued that the old free shopping bags were great as garbage bin liners and if they were not available then alternative bags, again plastic, would have to be purchased for the purpose.

Though many states and localities are waking up to their water shortages and taking steps to plan for “peak water”, people generally continue to waste water and to ignore the energy-water link. In 2004 the Natural Resources Defense Council did a study in conjunction with the Pacific Institute called “Energy Down the Drain” on how saving water saves energy. We need to do more to spread the word. [...]
