Environmental Graffiti found ten oases in the middle of cities that provide a good dose of nature for urban dwellers. Some are big enough to have hiking trails, lakes, zoos, forests, gardens, and even observatories. These 26 pictures are a refreshing treat for the eyes! Pictured is the gorgeous Butchart Gardens on Vancouver Island in Victoria, B.C. Link
