Light pollution w/ Richard Easther: January 27, 2023

University of Canterbury Astronomer Professor John Hearnshaw is calling for national legislation to limit light pollution.

He proposed a national law that would set new controls on outdoor lighting, such as 10pm curfews for illuminated advertising signs, limits on what street lights could emit, and reductions in blue light across cities and towns.

David spoke to Richard Easther from the University of Auckland about what would happen if New Zealand started to regulate light pollution.
