The International Union for Conservation of Nature (IUCN) works to help nations find "pragmatic solutions" to the world's most difficult environmental and developmental challenges. The organization's multimedia page is home to dozens of wonderful videos, photos, and audio content. Readers may want to start with the Video area, where they will find beautifully filmed productions shot around the world, such as "Berlin - the value of green spaces for sustainable future" and "Energy efficient housing in Palau." The Photos area is equally impressive. Here readers will find fascinating stills in four categories: People and Nature, Biodiversity, Nature's Benefits, and America's Cup Healthy Oceans Project. (One caveat, the categories link to Flickr sites, which can be a little slow to load.) Finally, Audio items include interviews, news reports, and other environment-related broadcasts.
