Broker Introduction. This curriculum unit on contemporary human-environment relations focuses on the interplay of cultural, ecological, environmental, and human health issues. It is a case study of an environmental disaster near Donana National Park, Andalucia, Spain. Donana is considered the most important wetland in Europe. Its marshes, mobile dunes, and forests are unique. In April 1998, a sudden burst in a zinc mine waste reservoir released a billion gallons of heavy metal contaminants into the Guadiamar River, a tributary of the Guadalquivir River, which forms the eastern boundary of Donana National Park. The toxic spill quickly was regarded as a national disaster in Spain, and it received extensive coverage in the press and in science journals. The highly acidic sludge, zinc, cadmium, arsenic, and lead pollutants that were released into the environment continue to threaten the ecology and the biota of this internationally significant wetland. I had the opportunity to visit Spain in the summer of 1998, just several months after the toxic spill occurred. The trip started and ended in Madrid, but the majority of time was spent traveling through the southern and southwestern regions of Spain, in Andalucia and Extremadura. A day excursion to Donana National Park gave me a chance to make first hand observations of the wetland (albeit during the dry season), to discuss ecological and environmental issues with park and tour group representatives, and to obtain some highly informative literature on the region.
