Environmental science is considered the be an interdisciplinary field because
Many science and non-science fields of study, such as economics and politics are included.
Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
What is the independent variable?
pH of soil

intrinsic
Major contributing factor to resource depletion
Developed countries have a much higher rate of resource consumption than others.
The difference between non-renewable and renewable resources
Renewable: Replaced naturally
Non-renewable: Finite resource
Which period of human history has created the most water pollution?

Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
The number of strawberries produced is known as
the dependent variable

The number of different species within an ecosystem
An environmental ethic that places an emphasis on short term human interest

Most of today's environmental problems began during which period(s) in human history?
Industrial Revolution
Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
What are 3 constants in this experiment?
Answers will vary. EX: size of pot; amount of water, type (species) of strawberry, source of soil, where grown (light, temperature, etc.)
Two extrinsic values of the James River
Answers will vary. EX: Fish; barge transportation; fresh water; river rafting excursions (businesses)
What is the measure of human demand on the Earth's ecosystems?
Ecological Footprint
Conflict due to overuse of SHARED resources
Tragedy of the commons
How did the Industrial Revolution affect human population growth?
Allowed it to INCREASE thanks to mass production of foods, medicines,etc
Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
What might Jane's hypothesis be?
ANSWERS will vary, but must be quantitative and include a trend. EXAMPLE: As the pH decreases, the number of strawberries produces will decrease.
According to the law of supply and demand, if the amount of oil extracted worldwide were to increase and demand stayed the same, the price of oil should _____.
Decrease
Exhaustion of raw materials within a region
Resource Depletion
