Le biocarburant aux micro-algues, une alternative au pétrole ?

Le biocarburant aux micro-algues, une alternative au pétrole ? | Sustain Our Earth | Scoop.it

INNOVATION - Fermentalg, jeune société girondine a présenté un véhicule roulant avec un biodiesel intégrant 7 % de biocarburant d’algues, en décembre 2012. Le rendement est trente fois plus élevé que l'agrocarburant issu de l'huile de colza ou de palme et ne nécessite pas de mobiliser des terres fertiles.

Stupidity Is Not A Valid Defense For Us - The Automatic Earth

Stupidity Is Not A Valid Defense For Us - The Automatic Earth | Sustain Our Earth | Scoop.it

If we can't plead stupidity, what else is there? How do we live with ourselves? Is it all the stuff we buy that manages to numb our brains and consciences?

 

When I see a headline like this one at Bloomberg today, World Needs Record Saudi Oil Supply as OPEC Convenes, there’s just one thought that pops into my head: what the world needs is for us to stop doing this thing we’re doing. Even apart from peak oil concerns, it’s obvious we’re going to run out at some point or another, and it doesn’t matter whether that’s tomorrow or at some other point in the future, though we do know it’s not going to take another 100 years, or even 50.

 

And nothing will ever take the place of oil; once those unique carbons are gone, that’s it, we’ll have to find a completely different way of running our societies, and if we’re not smart enough to prepare for that beforehand, we’ll be cats fighting in a sack and use the last scraps to kill off each other. And our legacy won’t be the Greek thinkers and Picasso and Dostoyevsky and Walt Whitman and Maria Callas, since there won’t be the means for our children anymore to share what makes man great between them. Our main legacy will instead be bloodshed, we will have gone the exact same path that any non-thinking or even primitive organism would have taken, who don’t have opera or philosophy or poetry to their name.

No False Choices: To Preserve A Livable Climate, We Need To Slash Both CO2 And Methane ASAP | Sustain Our Earth | Scoop.it
It is a false choice that we must choose between cutting CO2 (the biggest long-term threat to the climate) and super pollutants like methane (that are far more potent at trapping heat in the shorter term). We must do both to sustain a livable climate.

Etude - Les oiseaux sont aussi victimes des néonicotinoïdes

Paris, 9 juil 2014 (AFP) - Déjà soupçonnés de tuer les abeilles, les insecticides néonicotinoïdes affectent également les oiseaux, peut-être en décimant les insectes dont ils dépendent pour se nourrir, selon une étude néerlandaise publiée mercredi.

Tomgram: Michael Klare, Fighting for Oil | TomDispatch.com

Tomgram: Michael Klare, Fighting for Oil | TomDispatch.com | Sustain Our Earth | Scoop.it

Call it a double whammy for the planet or simply irony with a capital “I.”  As the invaluable Michael Klare, TomDispatch regular and author of The Race for What’s Left, points out today, if you scan the planet for conflict, what you’ll find from Syria and Iraq to the South China Sea are a series of energy wars -- fossil-fuel conflicts to be exact. 

 

At present, despite some hopeful signs, this crazed planet of ours is still a ravenous beast that only fossil fuels can sate.  No question that conflicts and wars are terrible things.  Just consider the million new refugees being generated by the disintegration of Iraq in a blaze of warfare and sectarian killings. 

 

But oil wars add a grim twist to the mix, because when they’re settled, however miserably or bloodily, the winners take to the oil rigs and the refineries and pump out yet more of the stuff that puts carbon dioxide and methane, both greenhouse gases, into the atmosphere and, as in the Middle East today, creates the basis for yet more conflict.

 

That region has been going through a period of heightened dryness and drought that researchers from the National Oceanic and Atmospheric Administration believe to be caused, at least in part, by global warming.  This winter, the driest in decades, Syria and Iraq in particular have experienced a severe lack of rainfall in what should be the wettest part of the year and record heat as well.

Dubai's Climate-Controlled Dome City Is a Dystopia Waiting to Happen | Motherboard.vice.com

Dubai's Climate-Controlled Dome City Is a Dystopia Waiting to Happen | Motherboard.vice.com | Sustain Our Earth | Scoop.it

Dubai is building "the world's first climate-controlled city"—it's a 4.3 mile pedestrian mall that will be covered with a retractable dome to provide its shoppers with air conditioning in the summer heat. The Mall of the World, as it's called, will become the sort of spectacular, over-the-top attraction Dubai is known for. Shortly after, it will probably become an equally spectacular real-world dystopia.

 

By sectioning off a 3-million-square-foot portion of the city with an air conditioned dome, Dubai is dropping one of the most tangible partitions between the haves and the have nots of the modern era—the 100 hotels and apartment complexes inside the attraction will be cool, comfortable, and nestled into a entertainment-filled, if macabre, consumer paradise.

 

The masses, including the underpaid immigrants who will no doubt help build it, may be free to wander through by day, but they will surely find no residence there. According to the UN, a full 88.5 percent of United Arab Emirates residents are foreigners; most are migrant workers, who receive few protections from the nation's labor laws. There are estimated to be hundreds of thousands of migrant workers in Dubai alone, many of whom toil in conditions that resemble indentured servitude.

Des fientes de baleines contre le réchauffement climatique

Des fientes de baleines contre le réchauffement climatique | Sustain Our Earth | Scoop.it
La chasse aux baleines pourrait avoir accéléré le rythme du changement climatique. L’hypothèse découle d’une étude scientifique qui révèle que les fientes de cétacés ont une grande capacité d’absorption du CO2. Un rapport de l’université de Vermont, publié le 3 juillet dans la revue « Frontiers in Ecology and Environment », souligne l'importance des baleines dans l'équilibre des écosystèmes marins. Leurs déjections auraient en effet de nombreuses vertus écologiques. Les fientes relâchées à la surface, très appréciées des planctons, sont particulièrement riches en nutriments. Mais elles ont surtout une capacité d’absorption du CO2 exceptionnelle pour un être vivant.

Racing Toward Total Extinction | Exposing the chemtrail-geoengineering coverup

Racing Toward Total Extinction  |   Exposing the chemtrail-geoengineering coverup | Sustain Our Earth | Scoop.it

While billions around the globe still occupy their time with completely meaningless distractions and entertainments, life on Earth is literally imploding. The level of mainstream media spin and omission in regard to what is unfolding is difficult to comprehend. The general public is all too willing to accept the factless facade that is fed to them day in and day out while life on Earth disintegrates around us all. Our collective future quite literally now rely on those that are awake and willing to help sound the alarm. Standing still and complaining to others about the converging catastrophes will not help our situation. We must all learn to effectively reach out to all the groups, organizations, and individuals that are still oblivious to the immediate peril we face. Every single day matters.

Bamboo could help developing cities urbanize

Bamboo could help developing cities urbanize | Sustain Our Earth | Scoop.it

What if there were a local, renewable material that could be used instead of steel in reinforced-concrete buildings? And what if that substitute could be manufactured easily? These questions have motivated Dirk Hebel, an assistant professor of architecture and construction at the Future Cities Laboratory, in Singapore, to investigate a bamboo fiber composite as a possible substitute for steel reinforcement in concrete. The Future Cities Laboratory is a research arm of ETH (Eidgenössische Technische Hochschule) Zürich, in Switzerland, and is the first program under the newly formed Singapore-ETH Centre for Global Environmental Sustainability, which conducts multidisciplinary research to foster urbanization that conforms to the principles of sustainable development.

PIRatE Lab's curator insight, Today, 1:41 PM

There are many "ifs" here, but this is an intriguing approach that may avoid the pitfalls of previous attempts at using bamboo for such a strengthening role in buildings.  I suspect that this won't work, and am always worried when press releases go out before a project has even preliminary results, but I very much like the innovative and new idea-type approach these folks are taking here.
