No matter how much I want a Jurassic Park, I say it shouldnt happen. Why? Simply because keeping animals in captivity is wrong.
What load of BS? Sometimes, keeping animals in captivity is necessary to save them from extinction. Check the case of Siberian tigers. There are only around 100 of them out there in the wild. However, the captive population number around 4,000. If not for the gene pool inputs from the captive population, the tigers might have died out long ago in the wild.
