APES Unit 1 Test Review with
Complete Solutions
sustainability - ANSWER-living on Earth in a way that allows humans to use its
resources without depriving future generations of those resources
eco footprint - ANSWER-measure of how much a person/group consumes, expressed
in area of land; output from the total amount of land required to support a person's
lifestyle
per capita - ANSWER-per person
reduce - ANSWER-reduce the inputs of materials to a system to reduce the outputs
(less material used —> less material to discard)
reuse - ANSWER-using a product or a material that was intended to be discarded
recycle - ANSWER-materials destined to become MSW are collected and converted
into raw materials that are then used to produce new objects; last choice because
requires more time, energy, and money than other R's
Close looped recycling - ANSWER-recycling of a product into the same product
open-looped recycling - ANSWER-one product recycled into another product
composting - ANSWER-creation of organic matter (humus) by decomposition under
controlled conditions to produce an organic-rich material that enhances soil structure,
cation exchange capacity, fertility
landfill - ANSWER-carefully designed structure built into or on top of the ground in which
trash is isolated from the surrounding environment (air, rain, groundwater) — isolation is
accomplished with a bottom liner and daily covering of soil; creates conditions where
trash will not decompose much
building a landfill - ANSWER-start by proposing a landfill — must do an environmental
impact study on proposed site to determine area of land necessary, composition of soil
& bedrock, flow of surface water over site, impact on local environment and wildlife,
historical or archeological value of site —> obtain permits, raise money from taxes or
municipal bonds —> start construction
