<p>(Earth Focus: Episode 24) Three new films are exploring some of the pressing issues related to water.

He draws on examples from drought-plagued countries like Australia to see how we can cope with exacerbated drought and other worsening climate conditions in the future. In the film "Poisoned Waters," veteran journalist Hedrick Smith examines the health impact of toxic chemicals in our water, including endocrine disruptors — chemicals which can affect hormones and the endocrine system.
