Green Infrastructure for Sustainable Cities
A new collection of case studies describes how cities can successfully implement "green infrastructure" to process rainwater in ways that make urban environments more habitable.
What's the Latest Development?
A series of case studies just released by the American Society of Landscape Architects is a veritable "how to" guide for cities that want to cut building and utility costs while creating more habitable environments. "Such techniques as green roofs, roadside plantings, rain gardens, permeable paving, and rainwater harvesting." The techniques improve water quality and transform rainwater from a source of pollution into a valuable community resource. Half of the cases studied were retrofits of existing developments.
What's the Big Idea?
As cities continue to grow, they must do so in more compact patterns. Urban sprawl has wasted money and it makes cities unsustainable and unpleasant places to live. Caring for urban water resources by creating natural runoff systems, i.e. green spaces that allow rainwater to seep naturally back into the ground, is a good way to implement sustainable development. Such green spaces would scale back concrete use and other "gray infrastructure" while separating rainwater from cities' systems of sewage pipes.

- The campaign was one of the first to demand a guaranteed income for all poor families in America.
- Today, the idea of a universal basic income is increasingly popular, and King's arguments in support of the policy still make a good case some 50 years later.

For Damien Echols, tattoos are part of his existential armor.
- In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
- This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
- Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
