or abate serious public health problems.
Thirdly, the authors implicit claim that incinerators are economically
advantageous to landfills is poorly supported. Only two small economic benefits of
incineration are mentioned, while the costs associated with either burning trash or
switching refuse disposal systems are ignored. In all likelihood, such costs would be
significant, and may very well outweigh the economic benefits.
In conclusion, the authors argument provides inadequate justification for
switching from one disposal system to the other. As it stands, the argument takes into
account only a limited number of benefits from the change, while addressing none of its
costs. To better evaluate the argument, we must first examine all the health risks posed
by each refuse disposal system and conduct a thorough cost-benefit analysis of each
system, taking account of the cost of the new system, the cost of the changeover itself,
and the expected costs to the community of health problems resulting from each system.
