Myth of Inexhaustibility Current LectureI. SyllabusII. Introduction to CourseA. Fun fact: if you line up all insects on Earth, every 4th would be a beetleB. Globalization: world getting smaller; international integration arising from products of exchange and world viewsC. Sustainable Society: accommodates needs without compromising ability of future generationsD. One can live more sustainably by:1. Reduce consumption and recycle2. Unplug electronics3. Avoid excessively packaged goods4. Consume local goods5. Walk, carpool, public transitIII. Tragedy of the CommonsA. Defined: Short sighted use of natural resources for immediate gain without concern for future generations; opposite of sustainability B. Term that came from Garret Harden’s story about the common grazing lands in England C. “Commons” are the natural resource and the service it providesD. The tragedy is attributed to the domino effect of the overuse of the natural resource where too many people are taking advantage of it in a short period of time1. Example: Many people on campus don’t use the sidewalks, but will cut across corners on the grass. This would not be an issue if only one or two people These notes represent a detailed interpretation of the professor’s lecture.

However, the “short cut trails” are eroding the soil and causing the tragedy of grass (commons) to no longer grow along this over walked paths.IV. Sustainability YieldA. Defined: largest number of organisms that can be removed from a population without decreasing overall population numberB. This is why states have specific hunting and fishing seasons and licenses C. Other factors to consider: male-female ratio, gestation period, life expectancy and life cycle1. Example 1: 100 walrus produce 50 babies. How many can be harvested without decreasing the overall population? Answer: 100-50= 50 Only 50 can be harvested so that 50 babies can still be produced. 2. Example 2: In some countries sea turtle eggs are sold in down town markets. How can these be if sea turtles are said to be a protected species? The people discovered that turtles lay eggs intwo waves. The first wave of eggs is usually washed away by the tides to make room for the second wave of eggs. The people observed this and figured that they could collect the first wave of eggs and still obtain maximum sustainability.V. Myth of Inexhaustibility A. Defined: belief that Earth’s resources cannot be used up and will always be there for our useB. Example: Many people believe that Oil will always be a resource on Earth; however, oil has already peeked. It can only decrease from this point
