Once I had a garden in Honolulu. I built stone terraces around an old mango tree, grew ancient crops, played with my baby girl. For the better part of a decade, I went there every other day or so. Took it on as a pile of rubble, left it as a little oasis of rich organic soil in the middle of a city.
I just looked at it in the google aerial view, and felt like I'd been kicked in the stomach. The mango and the terraces are gone. The big retaining wall that had kept this little place hidden was replaced recently, I guess, and they bulldozed the garden. Maybe it's buried under stone and concrete, but the life is gone.
