different ways humans manipulate their environment
- land(mining, farming, development)
- air(pollution, green house farming, climate change)
- water(pollution, transportation, run-off, sewage)
- soil(fertilizing
- biodiversity
- technology
- human population
natural environments provide ecosystem services such as….
free life supporting recourses:
- shelter
- clean water
- food
- clean air
- crops
- fisheries
- timber
environmental indicators
describe the health and quality of natural systems:
- biological diversity
- food production
- human pop
- resource depletion
- surface temp and CO2 concentrations
human sustainability
living in a way that allows humans to use resources without deriving future generations of those resources
sustainable practices
recycle, carpool, biking, compost, reusable water bottles, turn off lights, food with less packaging, using resources sparingly
ecological footprint
a measure of how much an individual consumes, expressed as an area of land
theory vs hypothesis
hypothesis: a testable conjecture about how something works, a prediction

what determines the price of a good
supply and demand
GDP vs GPI
GDP(Growth domestic product); values of all products and services in a year
GPI(Genuine process indicator): adds cost of pollution, service of people and environment, recourse depletion, health and pollution
Technology transfer
