Climate change has become a major issue in Australia in recent years. Much of the country's population appears to be losing its traditional water sources due to an increase in population in urban areas coupled with persistent drought.
As a consequence of the Big Dry, a decade-long drought, sheep farmers in New South Wales who cannot grow or afford to buy feed are forced to sell their livestock at a cut price. The buyers feed the animals on the worthless remains of crops that never grew large enough to be harvested. An alarming number of farmers without a future chose suicide to escape their troubles.
