A year ago, a strange sign was erected in the park. Why do you say it's strange? Because this sign only 10 centimeters high, do not bend down the words can not see, the sign begins to write: "Ground squirrels!" "Originally, this is to the ground squirrel to see the warning." \ n "... You continue to eat human food, will be more and more fat, and finally run, you have to be golden eagle or bear to eat ... "The thought of a curious tourist to make a wry face, I can not help but smile. Also think that in the Japanese zoo, see tourists continue to the bear's cage to lose food, hanging next to the "do not feed" signs, looks so weak. It's clear that some people see animals as they naturally want to feed them, but some people think it's wrong. It's hard to stick to the truth, but it's better to think more about space and to persuade people with a little humor.
