ISB exam 1 study guide Key concepts and ideas: Sustainability development that meets the needs of the present without compromising the ability of future generations to meet their own needs Gaia hypothesis levels of organization of the universe earth should be viewed as a system; it's selfregulating and a super organism (like the human body, it's self regulating and maintains balance) Planetary and biospheric corollaries co2 levels wetlands provide filtering for water co2 patterns: spring has more levels because plants are blooming and more oxygen is in the air fall and winter is when it evens out and the co2 levels start rising again Natural capital 1. resources 2. services resources which include geology, soil, air services, often called ecosystem services nutrient recycling, climate control, pollution control, biodiversity Factors of ecological footprint (measured in acres the multiplied by planet) where food comes from (local or shipped in), what kind of house you live in (big apartment, home, dorms), transportation (motorcycle, public transportation, car, bike) Globalization process of interaction and integration among the people, companies, and governments of different nations, a process driven by international trade and investment and aided by information technology more energy = more people positive feedback loop: one thing in system leads to something else which leads to original thing (warm climate use of air conditioners co2 emissions warm climate) Myth of inexhaustibly the idea that there is such a plentiful amount of a resource that there is no way we can use it all up Maximum sustainable yield Using a resource at a rate that does not exceed the growth so that future generations can use it Tragedy of the commons independently and rationally according to their own selfinterest behave contrary to the best interests of the whole by depleting some common resource. ex: overfishing in international waters Steps of the scientific method Observation Hypothesis Experiment Conclusion Publish Pure v applied science pure science seeks to identify and explain phenomena research applied science seeks to apply knowledge using technology or other mediums to test theories and make things (pure science is studying bugs, applied science is creating a water bottle based on bugs shape to gather water) Economic systems in ecology capitalist market: drive out competition global free trade access to more resources harmful costs being passed on!!! Full cost pricing (internal + external costs) price good based on internal costs (labor, supplies) which drive the market, and the external costs(human, environmental) that harm the environment example: a coalburning power plant will emit greenhouse gases that could impose health costs on society. And the noise that comes from wind power generation could cause sleep disturbances, anxiety and stress in susceptible individuals (external costs) along with the cost of labor and supplies (internal) Structure of planet core: solid, nickel and uranium (thermonuclear reactions) mantle: magma, liquid and moving crust: solid composed of plates the float on mantle Crusts: continental: igneous rock/granite LARGE crystals, LESS dense older oceanic plates: igneous/basalt, SMALL crystals, MORE dense Plate tectonics theory continental drift Wegener’s continental drift theory was the first step in the development of plate tectonic theory, the foundation upon which modern geology is built. What drives plate tectonics convection currents (think of a lava lamp lava heats at bottom, goes up drags plates, cools off, falls back down) Major factors that impact soil fertility soil and water minerals from bedrock geology nutrients from decomposition 1. macro nutrients: organisms require a lot (nitrogen and phosphorus) 2. mico nutrients: organism only need a little water and gas exchange too much water will drown roots particle size of soil too small particles results in soil compaction water cant get to roots Bad soil management trees cutting down roots get loose and leads to soil erosion driving on grass/heavy animals leads to soil compaction
