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
