The former wanted to cull the kangaroo colony that was growing at an alarming rate in their office campus at Canberra. The activists thought the very idea a sacrilege. The government's predicament is only a small replica of what is happening in much of Australia. Less food and fodder Apparently there are far more kangaroos in the island continent than people.
