life has existed on earth for - 3.8 billion years water covers _ of earth -3/4 earth is well suited because - -water covers 3/4 -habitable temps -moderate sunlight -oxygen and carbon dioxide provided -soil has essential minerals for plants highly developed countries - industrialized, low pop growth, high incomes less developed countries - low industry, high fertility, high infant rate, agricultural, high mortality rate, low income renewable resources - solar energy, wind, tides, water energy, soil, air, water, biological diversity (forest, food crops, fish) nonrenewable resources - metals, nonmetal minerals, fossil fuels sustainable development - economic development that meets the needs of the present gen. w/o compromising future gen. ecological footprint - avg amount of land, water, and ocean required to provide that person with all the resources they consume environmental sustainability - ability to meet current human need for natural resources w/o compromising the needs of future dy of the commons -solving environmental problems is a result of struggle b/w -short term welfare -long term environmental stability + societal welfare theorized tragedy of the commons - Garrett Hardin neg. feedback - change triggers a response that *counteracts* the changed condition pos. feedback - change triggers a response that *intensifies* the changing condition inductive - used to discover general principle, seeks unifying explanation for data deductive - proceeds from generalities to specifics, adds nothing new to knowledge but makes relationships among data more apparent energy must be supplied from an ___ source to keep biological processes going - external energy flows in a __ __ patch through systems and into a _ _ _ - 1-way, low temp sink 1st law of thermodynamics - energy is neither created nor destroyed 2nd law of thermodynamics - with each successive energy transfer, less energy is available to perform work population (a, b?) - biotic community (a, b?) - bioticecosystem (a, b?) - abiotic and biotic order of habitats.. - species/population, community, ecosystem, biome, biosphere
