Senior doctors today published a report warning that
climate change
is the biggest threat to global health of the 21st century.
Rising global temperatures would have a catastrophic effect on human health,
the doctors said, and patterns of infection would change, with insect-borne

"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.
