1. define environmental the study of how the natural world works, how our
science environment affects us, and how we affect our envi-
ronment
-emphasis on population growth, resource depletion,
and environmental degradation
2. what is science, and -science: activities aimed at understanding the world
natural science? list around us
the steps of the scien-
tific method in order -natural science: understanding the natural and phys-
ical world
-theory, hypothesis, observations, confirmation/rejec-
tion
3. list the 5 spheres of -lithosphere
the earth system -hydrosphere
-cryosphere
-atmosphere
-biosphere
4. define resilience in -the ability of a system to maintain key processes by
the context of earth adapting to change/stressors
systems
5. define a tipping point a threshold beyond which an ecosystem cannot re-
cover from rapid change and stressors
different from a planetary boundary -- tipping points
come after, where the boundary is an early warning
system
6. define planetary -a defined space that acts as a buffer zone for re-
boundaries and ex- sponse time before a tipping point/global threshold is
plain how they work reached
green = safe zone
yellow = zone of uncertainty

red = high risk
planetary boundary = the intersection of green and
yellow
threshold = the red and beyond area
7. what are the 9 plane- -climate change
tary boundaries? -novel entities
-stratospheric ozone depletion
-atmospheric aerosol loading
-ocean acidification
-biogeochemical flows
-freshwater use
-land-system change
-biosphere integrity
8. define the holocene holocene
and the anthro- -previous period of temperature and earth system
pocene stability, allowed for civilization to develop
-the only phase that could support humanity
anthropocene
-humans are the primary drivers of change at the
scientific level
-triggering new ecosystem regimes, new biophysical
logic, new species taking over, ecosystem becomes
LOCKED
-unable to function in the same way as before, affect-
ing all other systems around it
-these changes are rapid, unpredictable, and can be
irreversible
-we NEED to bend the curve down to a holocene-like
state to survive
9. what are the -population growth; 20/80 dilemma where most envi-
4 factors making ronmental impact comes from 20% majority
up the "quadruple
squeeze?" -climate agenda; greenhouse gasses must come
down to avoid the 2 degree temp increase, which
would destabilize our ice sheets
