$1 billion earmarked to battle chocolate shortage

Chocolate manufacturers are teaming up for the first time to tackle the dwindling supply of cocoa.
They are giving farmers $1 billion to help them boost their crops in the face of changes in the climate.
With growing demand, cocoa prices are up 40 percent and will bring higher prices.
Cocoa trees take two to four years to yield beans, so output can't rise rapidly from one season to the next.
