I'm not sure that putting animals in cages so humans can gawk at them is a completely good idea, but on the other hand, they are educating children and some adults. That and I have heard of breeding programs that have aided in reestablishing some depleted populations.
*shrug* Since I am willing to say that a Zoo is somewhat better than neutral if done right. Its a bit above my pay grade and I just got back from a workout so on to the story.
A man built a zoo..
He made the entrance fee $60 but no one enters his zoo..
He reduced it to $40 but still no one came.
He made $10 for the entrance but no one still enters..
What the man did, because no one was coming in even though the entrance fee was very low, he just made it FREE.
As a result, many people entered the zoo and it was filled with people. More than 4000 people came in.
He then quietly locked the zoo gate, freed the crocodiles, lions and tigers and then made an exit fee of $100.
Everyone paid immediately just to get out!
Since that one was a bit on the short side, here's another one that's a bit on the short side!
A man walks into a museum
He sees a dinosaur skeleton and asks the tour guide “How old is that skeleton?”
The tour guide says “65 million and 3 years, 5 months and 12 days.”
“Wow” says the man, “How do you get such a specific measurement?”
The tour guide replies “Well it was 65 million years old when I started working here. I’ve been here for 3 years, 5 months and 12 days.”
