This worries me on a few of different levels. First, it is sad for the livestock that they die a painful death from a very preventable disease. Second, it is a public health threat. Third, people who can't afford to immunize their livestock will start killing bats to alleviate the problem, which will create a bunch of new problems.
It is frustrating, because I can't even think of a solution, besides, perhaps, the government offering free immunizations to those who can't afford it...but then perhaps those people can't really afford to have the livestock, so why enable them?
