A barge trip is de rigueur for this Geo Quiz. We're traveling along a peaceful and picturesque waterway in the south of France. It's called the 'Canal du Midi'.

We want you to name the city in southwest France where this canal originates. It's known as the "Pink City" because of its light red brick buildings.

And the answer is Toulouse. Approximately 42,000 trees that line the Canal du Midi in France are under threat. A fungus has been attacking the trees for a few years and it has indeed been very difficult to control it from spreading. Specialists predict that all the trees will have to be chopped down, burned and replaced over the next 20 years. Anchor Lisa Mullins speaks with Guardian journalist Kim Willsher.
