Learning Goals
1. Compare and contrast risk, perception of risk, hazard, and vulnerability.
a) Risk - Probability that any given hazardous event might occur
b) Perception of risk is a prole sie huas do’t deal ell ith proailities ad
our perception of risk is flawed
c) Hazard - Any event or situation that could cause human (Deaths, injuries) or
economic harm (property and prosperity)
d) Vulnerability – a weakness that could be affected by a disaster
2. Recognize how poor humans are at judging risk and how your perceptions skew your
ability to judge risk. Humans are bad with big numbers, ie. Lottomax where theres only a
1 in 28,633,528 chances of winning.
3. Relate natural-disaster risk & intensity to frequency, return period, and consequences
(costs). Illusion of control, exposure, experience, number of deaths, environment,
research studies, media, primal fear, pain and age.
4. Describe population growth and explain why it is important for natural disasters.
Historically, our population has been experiencing exponential growth but there has
been a decline in this growth and is now only linear.
With warning, people can be saved from disasters, although infrastructures are
destroyed. In the future, with more people, infrastructures become more important and
vulnerable and people are less likely to be evacuated.
5. Eplai ho Earth’s arrig apait ad oerpopulatio are related to the fate of the
human race, and anticipate your role in it. Carrying capacity is the population that can
be sustainably supported within a given domain but if overpopulation occurs this
exceeds the carrying capacity of earth which can lead to an imbalance between supply
and demand.
