Q: Before 1939 malaria was still a disease that people in southern Ontario could get and die from. In 1939, DDT became available; by 1950, it had completely eliminated the mosquito that carries malaria. People then learned about DDT's health hazards and, by the 1970s, DDT was banned. The mosquito that carries malaria is now back. If malaria comes back, people may want to spray again with DDT because they know it is less dangerous than malaria. This is an example of how human perception can ________.
