Increasingly green roofs are being recognized as environmental workhorses. They lighten the load on municipal sewage treatment facilities because they retain up to six times more storm-water than conventional roofs. They reduce urban heat islands, absorb air pollution and store carbon and they can be an aesthetic option to tradition roofs.

I’m blogging for WorldChanging Austin, one of nine local editions of WorldChanging.com. There was a party Tuesday evening in Austin to celebrate the release of WorldChanging: A Users Guide for the 21st Century. The party gave those of us blogging for WorldChanging Austin a chance to put faces to names and to talk about ideas for future blog posts.

Solar Austin hosted the party Tuesday for Alex Steffen, co-founder of WorldChanging. He talked about the importance of focusing on solutions to the Global Problematique and how astonished he was by the number of existing solutions. He shared his favorite world changer, a flower that turns a different color in the presence of the chemical released by decaying land mines.

The best part of the evening was talking with Austin world-changers about their inspiring projects and unique solutions for a sustainable future.I’m proud to be blogging for WorldChanging and encourage you to check both WorldChanging and WorldChanging Austin to learn about creative solutions for global challenges.
