Translation of züchten

From time to time I listen to my old CD collection. However, most of the CD boxes, meaning the covers, are so full of dust that one can hardly see the image. Taste changes with the age, that is known.
I almost forgot to tell you, that the water was brown, despite of its name... Anyway, as I was already close to my next destination I went and consulted with a tourguide of Austrian travelers.
On the next day we took the tour to see the Peninsula. The tour itself was very boring and the guide had really not much to say that would interest me. The area was barren and completely flat.
