March 22nd is World Water day.
While the world’s population tripled in the 20th century, the use of renewable water resources has grown six-fold. Within the next fifty years, the world population will increase by another 40 to 50 %. This population growth – coupled with industrialization and urbanization – will result in an increasing demand for water and will have serious consequences on the environment.
To that end I have posted below several links to sites and resources. Perhaps the topic would be suitable for Group 4? Perhaps they will give you ideas to possibly incorporate within Earth day (Aprill 22nd)
