I saw the following things in Spring Hill, Brisbane, which made me think about the environment either in the sense of nature reclaiming land over man-made objects or how man has made old technologies more environmentally friendly. See below.
I thought this was pretty cool - the grass emerging through the pavement in search of light and the opportunity to survive.
This one being an old street lamp shade, which 'modern man' has added the energy smart light bulb to. I think it is a nice touch that Council has retained the old light fittings. This just adds to the area's charm, with many of the old heritage listed homes still standing, albeit some of them renovated to more modern standards. The light bulb is a nice compromise between modern 'necessities' and heritage values.
