Vanessa Quirk Tim De Chant argues that the practice of drawing trees on top of skyscrapers in architectural renderings should stop. First, because pretty, high-altitude foliage is the first thing that cost-conscious developers jettison when the actual building is underway; but secondly, because trees can't really survive at that altitude:
There are plenty of scientific reasons why skyscrapers don’t—and probably won’t—have trees, at least not to the heights which many architects propose. Life sucks up there. For you, for me, for trees, and just about everything else except peregrine falcons. It’s hot, cold, windy, the rain lashes at you, and the snow and sleet pelt you at high velocity. Life for city trees is hard enough on the ground. I can’t imagine what it’s like at 500 feet, where nearly every climate variable is more extreme than at street level.
Wind is perhaps the most formidable force trees face at that elevation. Ever seen trees on the top of a mountain? Their trunks bow away from the prevailing winds. That may be the most visible effect, but it’s not the most challenging. Wind also interrupts the thin layer of air between a leaf and the atmosphere, known as the boundary layer. The boundary layer is tiny by human standards—it operates on a scale small enough that normally slippery gas particles behave like viscous fluids.
Bottom line: if we're going to have skyscrapers, let's build them without the illusion that they'll harbor high-altitude forests.

Adam Young sez,
A developer made a game that's a spin on the old "waterworks"/"pipe mania" type game with an oil pipeline theme... complete with pixel-art anti-pipeline protesters. Like most indie developers, they were eligible and applied for funding from a variety of sources. They are donating a portion of the proceeds to the David Suzuki Foundation.
Apparently this made some blowhards angry, who think that "tax dollars funded the game" and shouldn't fund a game about blowing up pipelines, and that the developer donating to a non-profit charity somehow constitutes an ethics violation, having received so-called "tax-dollar funding". Tax breaks and grants and things are available to all sorts of content and media producers in Canada. Game development and film production and the like are industries that are very active here. It's also not illegal to donate proceeds to non-profit charities.
Gmoke sez, "Former Brazilian Environment Minister Marina Silva and recent Green Party Presidential candidate (she came in third to force a run-off election) launched the Sustainability Network in Brasilia on 16 February, 2013 and seeks to collect the required 500,000 signatures by September 2013 to become a legally recognized political party. From Sustainability Network's political manifesto (PDF):
We believe that networks, as a means for meeting and organising, are an invention of the present that bridge to a better future. Therefore, it is through networking with society that we want to build a new political force, with alliances underpinned by an Ethics of Urgency, aiming to construct a new model of development: sustainable, inclusive, egalitarian and diverse.

Gmoke sez, "Two years ago, two Bedouin women, Rafea Al Raja and her aunt Seiha Al Raja (Um Bader), returned from a six-month solar engineering training at the Barefoot College in India as 'solar engineers' to start a training center for other women. Although they solarized 80 houses in their village, the government of Jordan, NGOs and international organizations have shown little or no interest in their work. Even with a documentary on their training and projects at home, 'Solar Mamas', there hasn't been enough funding to sustain their work and their dreams.
“We are still not working and the training has not started either,” Rafea told The Jordan Times in an interview on Saturday.
They came with hope, she said, but this hope is fading away. The government, NGOs and international organisations are showing little or no interest, according to FES officials, leaving the project stranded in the desert.
“Now even our fellow villagers have started to make fun of us because they see nothing is happening on the ground,” said Rafea, who with her aunt were received with festive firing and an “official” ceremony upon their arrival from India.
The situation took a dramatic turn for both Rafea and Um Bader. Although they provided solar energy to 80 houses in the village, they are now facing the darkness of personal problems that have plighted them since they completed their training in India.

Tristan from Open Source Ecology sez, "This comprehensive, user friendly video shows you how to assemble the Powercube; Open Source Ecology's modular power unit. This machine can be used to Power any of the 50 Global Village Construction set machines, including the Liberator CEB Press." (See today's earlier post on the CEB Press).
