[Submitted by: Paul Christmas] "The following site has a detailed section on freshwater and many other topics. It will be useful for the options section of the IB and in future will develop sections for the core. A key highlight are some of the detailed case studies. However the site is under development and so some section are are not complete. Some food and health case studies are required and the extreme environments sections is still being written. The site will be useful for both students and teachers of IB geography but has not been written exclusively for the IB."
