Is the Ark a possible feat?
One Elephant can eat 200 lbs of food per day, and drink 50 gallons of water. Currently there are 3 species of Elephants, which would make a total of 6 on the Ark. To feed all six, for only the 4 month stay on the boat, the total food needed; 72 Tons of food, and 6000 gallons of water.
This does not include the food needed to sustain the six animals once they land on high ground. The earth being covered by water for almost 4 months would devastate the Earths eco system for food.
We also have an exercise problem. In the wild, they can cover up to 50 miles in a single day if food is scarce, but usually travel a few miles every day. But Elephants require exercise or they die prematurely.
We also have the maintenance problem. Animals in captivity require human care. With only 8 on the vessel, this floating Zoo housing millions of species is understaffed. (San Diego Zoo has about 400 Species.)
We also have the "Bathroom" problem.

Besides the Elephants, we have other species on board needing a special "Environment" to keep them alive. Penguins need land, water, and cold temperatures. Hippo's need land and water and warm temperatures. Oh, and don't forget the "Bathroom" problem, and the food problem (Penguins need fish, Hippos need plants, and enough for over a year of being on the high seas, plus the time of a whole new eco system developing).
We also have a Boat load of meat eaters. Tigers, alligators, Bears, Snakes, Dogs, Wolves, Ferrets, hyenas, mongooses, and so on. These fanged creatures lose their cool when they get hungry!!
And the "Bathroom" problem.
Estimates prove, the Ark could never house the millions of creatures, lacking room, food supply, sanitary conditions, exercise, and man power to care for the amount of life on Noah's Ark. Next time you go to the Zoo, look at the effort required while keeping animals in captivity.
