The lessons in the following toolkit are designed to guide Grade 6 students towards an early understanding of climate change, and the impact it is having on all living things. One of the consequences of these changes is the increasing presence of climate sensitive infectious diseases within Canadian communities. Climate sensitive infectious diseases include many zoonotic, water-borne and food-borne diseases such as Lyme disease, West Nile virus, hantavirus, E. coli, giardiasis and salmonellosis.
