The All-Hazards Approach is a crucial concept in disaster planning. It is also known as the agent-generic approach. All-hazards or agent-generic disaster planning means that emergency managers do not need to create separate plans for each specific type of hazard. For example, Denton County does not need three separate disaster response plans for tornadoes, floods, and winter storms; it only needs one. Chapter 6 in the textbook explains the rationales behind this concept. Please (1) explain what a hazard agent is (2pt) ; (2) identify TWO rationales for the all-hazards/agent-generic approach (8pt)
