When different types of environmentalism collide

What happens when two different types of environmentalism collide? Balmoral Station, near Lake Tekapo - is owned by the Simpson Family, headed up by Andrew and Karen Simpson. They had the idea to convert a slice of this station - 113 hectares of Crown lease land - into a solar farm. The Simpsons applied for this to happen last year, but last week their application was denied - because of the potential effects on the ecology of the area. Andrew Simpson joins us.
