2:20 The Decline of Detroit

Detroit was once America's fourth largest city, a thriving industrial metropolis of 1.8 million people. Today, much of the grandiose architecture of Motor City is crumbling and abandoned as its people desert the city centre for outlying towns. Schools and hospitals have closed and services shut down. Since 1950 its population has more than halved to 750,000.

Auckland-based photographer Frank Schwere went to Detroit to document its decay. His work is on show at Two Rooms gallery in Auckland and is part of the Auckland Festival of Photography.

To some Native Americans it's a sacred plant, one that Captain James Cook brought to this country in 1769. Tobacco companies call it 'a normal and legal product', but there's still an air of secrecy around growing and processing tobacco for personal use. It's been 16 years since the pin was pulled on our commercial tobacco growing industry, and it was generally believed that growing the plants was then illegal. But that's not so. Sage Forest chats to some home-growers about the perceived benefits, and looks into legalities.
