The necessity of green

Perhaps that's the 2007 trend I find the most important (since we now are in 2008 and can look retrospectively): the grass was green (Rio de Janeiro, Brazil)

A patch of green (Geneva, Switzerland)

Interesting pavement (Seoul, South Korea)

"the grass was green" (Lyon, France)

All these encounters with fake grass in different parts of the world (over the last year) always make me smile and think about how our relationship to nature is important, awkward and controversial. "Green coverage" appears to be the most ridiculous way to convey a sense of nature, showing how it's important for human to still be close to it in contemporary cities. What does that say about urban informatics/computing? There is really a need to be closer to Nature but the proposed solution in these examples is flawed from the beginning.
