The prologue to this fine digital collection crafted by the Library of Congress notes that "Environmental issues affect everyone on planet Earth - the quality of the water and food we consume, the air we breathe, and the parks we enjoy." The images included here are meant to complement an ongoing in site exhibit at the Library, and they include images from the famous editorial cartoonist Herblock and well-known photographers like Sam Kittner and Ansel Adams. Visitors can read the About area to get a bit of background on the exhibit and then check out the "Exhibition Items" area. Here they can view all 39 items, which include dramatic images of environmental degradation and Herblock's witty and poignant India ink drawings which made him famous around the world.
