The document discusses three locations chosen for filming a documentary about animals and human relationships with animals. The first is Brecon National Park in Wales, which is chosen to show typical farm animals in England. The second is Sanlucar De Barameda Beach in Spain, where skilled horse jockeys race along the beach, providing an original and exciting event to film. The third location is Donana National Park in Spain, which contains much protected wildlife but will be difficult to film due to remoteness and dangers.
