I came across this picture this week from a 
trip I took to Australia about a year ago. I was so struck by what a marvelous idea it was that I had to stop and take a picture. That black rectangle is a rubber mat, like you sometimes see on children's playgrounds. This mat keeps the roots from the trees along the road from buckling the sidewalk. In Amsterdam (where I live),the city solves this problem by cutting down trees that get big enough to push the sidewalk up with their roots. I find this solution far preferable.
I took this picture when walking to an ex-colleague's house in St. Kilda near Melbourne to have dinner. I found out later that he and his wife had moved to the country, and lost everything to the recent brush fires while going to the grocery store. The devastation of these fires has been unimaginable, in a magical part of the world. The Australian Red Cross is accepting online donations for victims.
