Biology Notes 1/27/2016 Every activity we participate in affects our environment. Why use the term national capitol? “Capital” implies a store of wealth that can generate interest. You can live off the interest indefinitely, but if you can start spending the capital, interest declines and capital is exhausted. Textbook example: o 10% interest yields $100,000 per year indefinitely o spend $200,000 per year, broke in 7 years Our environment can be thought of natural capital. Natural resources +Natural capital=environment Humans can impact natural capital... How? Deforestation, global warming, etc. Population increase is a major part of increasing human impact on the environment. “Ruins are the result of when all man’s intentions are for personal benefit” Why don’t we manage our capital wisely? o Population growth, Unsustainable resource use, poverty, excluding environmental costs from market prices, trying to manage nature without knowing enough about it o This course is a lot about what we know, but it is also going to be how we feel about the things we already know and our relationship with nature. So what can we do? It is generally agreed that the “solution” to these problems is to make our society Sustainable. The textbooks definition: Sustainability: the ability of earth’s various systems to survive and adapt to conditions indefinitely, including humans. Biology Notes 1/29/2016 Where did the earth come from? This is a very widely asked question and there are many, many different explanations as to which is the most sensible. Most societies have had creation stories (“myths”) Much of this course can be thought of as the creation story as told by the science of our civilization. Big Bang Theory: There was a small lump of tremendous mass and temperature in the middle of nothingness. Very rapidly, spacetime comes into being and expands subatomic particles appear and form atoms, great clouds of matter roam the universe. All stars form from clouds of gas and dust which roam our universe. Eventually gravity causes them to collapse; since the cloud is spinning, material falls in along the “poles” faster than it does near the “equator”. This flattening results in a disclike object. Material slowly wends its way into the center of this disc, forming a new star. While the star continues to grow, lumps form in the disc which will ultimately become planets. This explains the Big Bang Theory. Our definition for now the accumulated ideas of “modern” our civilization about how things work what causes what, why it rains, why we get sick. Etc The “Scientific Method” a codification of the process of applying logical thought to answering questions about how things work
