The two thinkers are animals, but that is about the only part of this that is child-like about the site. A glossary is available by placing the mouse over bolded terms and looking at the cat's dialog box.
Coverage is eclectic.
Some topics seem quite arcane, others much broader, but all seem well researched, with information difficult to obtain elsewhere. An index of the site is also available. If you are seeking images of crops being grown around the world, this site is one of the best. Information about the images is displayed on the same page including the photographer, location and a detailed caption. This is a free, dynamic and authoritative resource established by collaborations within the botanical community.
