Memphis' Mud Island and the Pyramid (photo by Greg Gardner)

Spring 2007: With the Pyramind rising in the the background, the shores of the Wolf River in Memphis are lined with plastic bottles and other debris following a heavy rain. Karen Soro, who took this photo, is a Memphis realtor who lives and sells homes in the upscale Harbor Town community. She says it's almost impossible to sell Harbor Town properties when their front lawns and walking trails look like this.
