But if an earthquake occurs in a densely populated city with unregulated buildings, the risks from an earthquake could be detrimental. A good comparison for a disaster like this would be the earthquake that registered at 7.0 on the Richter magnitude scale in Haiti in January 2010; a highly populated city with poor construction caused more than 225,000 deaths and over $100 billion in damages. Such a disaster could have been avoided by regulated buildings during construction like in Mexicali, Mexico where a magnitude 7.2 earthquake only caused 2 deaths because of proper construction. 4) Section 19.2 Question #3: What factors have contributed to the steady decrease in the proportion of deaths cause by weather hazards? Between the years 1920 and 1950, a staggering 430,000 people died each year as a due to extreme weather hazards; this results to be roughly 200 deaths per million people each year. By the year 1990, that number dropped to a low 5 deaths per million people each year. The reasons behind this drop in death tolls can almost directly be attributed to the innovations in technology. With most weather related deaths coming from droughts, hurricanes, and floods, deaths have been avoided due to improved infrastructure and water supplies, improved forecasting and weather predictions, and relief efforts from both governments and organizations. 5) Section 19.4 Question #2: Why is it unlikely that we will ever be able to eradicate the common cold and the flu? There is a reason it is referred to as the common cold because almost everybody has had it one time or another in his or her lifetime. The same can be said for the flu or

influenza because it is such a common occurrence. Both of these diseases spread easily through the air and are considered respiratory diseases and both have many different mutations of their diseases. This is the reason that neither disease will most likely ever be eradicated. Some diseases can easily be defeated with one type of vaccination, but a disease such as the flu has many different variations like the swine or avian that it will never be eliminated. Both diseases can be spread to and from animals as well, making it even more challenging to destroy them and more unlikely that it will ever happen. Chapter 1 1) Section 1.1 Question #1: How are notions of equity and justice embedded in our current concept of sustainability? There is a large amount of variation in the world in the sense of humans’ well- being. For instance, here in the United States we often take for granted our clean water and obesity is very common, while other third world countries struggle to even find any clean water. This has caused the definition of sustainability to change to include the concept of equity and fairness without compromising future generations. 2) Section 1.1 Question #2: Most decision makers agree that equitable treatment and justice among humans must be part of any definition of sustainability. Why is that important?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
