grand national - selective breeding of a racehorse

The top trumps are fantastic. There are a lot of slides I would probably take out (all the ones about the races which different horses have won) but the selective breeding information is all in the there. Do you have the ethicially right or wrong sentences to include too? Love that you included the film "The Island" as some pupils might have watched this and you could encourage them to check it out! Or get a trailer for the film and then explain it.
