APES CH 1
Chapter 1 (Pg 3)
Environment – All the living and nonliving things around us
Inclusive sense (built environment, structures, urban centers) and broadest sense (complex webs of social relationships/institutions that shape our daily lives)
We are a part of the “natural” world and our interactions etc matter
Modify our environment – Our actions have enriched our lives (better health, greater material wealth, mobility, leisure time)
Impacts – Air & water pollution, soil erosion, species extinction
Environmental science – Study of how the natural world works, how our environment affects us, how we affect our environment
Natural resources – Various substances and energy sources that we take from our environment and that we need to survive
Renewable resources – Natural resources replenished over short periods
Sunlight, wind, wave energy
Nonrenewable resources – Finite supplies and formed much more slowly than we use them, no longer available once depleted
Mineral ores, crude oil
Ecosystem services – Planet’s ecological systems that purify air and water, cycle nutrients, regulate climate, pollinate plants & receive/recycle our waste
Arise from normal functioning of natural systems, not meant for our benefit, we could not survive without them
Beyond 6.9 billion people on Earth
Two phenomena leading to population increase
Transition from a hunter-gatherer lifestyle to an agricultural way of life = lived longer and produced more children (Agricultural revolution)
Industrial revolution = mid 1700s, shift from rural life to an urban society, mass production, powered by fossil fuels (nonrenewable energy sources i.e. oil, coal, natural gas)
The “tragedy of the commons” – Garrett Hardin, UCSB, 1968 essay in the journal Science
In a public pasture/common open to unregulated grazing, each person who grazes animals will be motivated by self-interest to increase the number of his/her animals in the pasture
No single person owns
