Veterinarian against Cloning

As an experienced pathologist who specializes in large-bodied animals, you have considerable discomfort about the monumental efforts, expense, and uncertainty involved in the care, maintenance, and management of cloned dinosaurs. Anyone who knows anything about modern ecosystems appreciates that boundaries are diffuse and that ecological "osmosis" takes place across invisible or non-existent borders. In other words, captive animals are not completely protected from outside influences and vice versa. You'll need to explore for the judges if it's relevant that dinosaurs were the dominant terrestrial beasts and if it's likely that the complex ecosystems in which they existed could be reconstructed in today's crowded world. Can scientists predict the changes that dinosaurs might induce in the habitats in which they are introduced? How would the dinosaurs be fed--would they need genetically altered plants from which the deadliest toxins have been removed? Angiosperms have experienced enormous evolution in the last 60 million years--would the dinosaurs have adaptations to aid in the digestion of plants they never encountered in the Mesozoic? Didn't somebody once propose that dinosaurs became extinct after suffering severe digestive disorders shortly after the evolution of the first angiosperms? And what about modern viruses--could they wreak havoc on the immune systems of the dinosaurs as well? Even new experiments to boost the immune systems of endangered species have not been able to save all members afflicted with a deadly virus. You'll also need to investigate if Mesozoic diseases that died out with the dinosaurs could be reintroduced into the modern world. Presently, Earth's biodiversity continues to suffer serious threats to its long-term health with many species extinctions caused by the introduction of "alien" species. Could reintroducing dinosaurs and other extinct life forms into habitats around the globe be the ultimate death knell for extant species by exposing them to Mesozoic viruses and other plagues to which they would have no immunological adaptations? After exploring these issues, you plan to end your testimony with an image that the judges will be unable to forget of a five-ton Triceratops with meter-long horns charging towards a bus filled with tourists... Dinosaur cloning is better left alone!
