3. How do Externalities tie in with Economics?!
Externalities are seen as events that can have an affect on something that's not really related to it in any way, but still affect severely. In most cases this occurs when natural disasters strike and the economy is left defenseless and end in market failure as a result. Most things are completely useless after a severe natural disaster. Usually public goods like highways that are destroyed, the process of restoring them again is rather difficult.These events almost always leave the consumers and producers at a draw in thinking what to do next. Keeping in mind that these positive and negative externalities’ costs and benefits are not reflected in the buyer and sellers pay.

4. Real Life Situations..
Hurricane Katrina distraught the U.S. immensely as it took around $ billion in damages. It ruined public goods such as highways and subways, all forms to travel. All in the states of Florida, Mississippi, Louisiana, and a few other southern states. Not only did it hurt public goods it wiped away many jobs from the people and interrupted the oil production down in the Gulf.
Other situations include earthquakes, as they hurt the house buying market considering the quakes can make the buyer question the house's condition. Making the market lower its prices to keep going and still sell houses.
