As this argument goes, most Australians live in cities and never get to see these animals. Marine par
12、ks allow the average Australian to appreciate our marine wildlife. However, in fact, there are many places where they can be seen in the wild. Moreover, these places do not charge an overpriced entry fee they are free. Dr. Alison Lane, the director of the Cairns Marine Science Institute, insists tha
13、t we need marine parks for scientific research. She argues that much of our - 3 - knowledge of marine mammals comes from studies which were undertaken at marine parks. The knowledge which is obtained at marine parks can be useful for planning for the preservation of marine mammal species. However, J
14、ones, a zoologist, explains that park research is only useful for understanding captive animals and is not useful for learning about animals in the wild. Their diets are different, they have significantly lower life lengths and they are more likely to have a disease. In addition, marine mammals in d

This position goes on to state that these tourists spend a lot of money, increasing our foreign exchange earnings

Indeed, surveys of overseas tourists show that they come here for a variety of other reasons and not to visit places like Seaworld.

In a word, perhap
