Important People/Laws
•Paul Elrich: predicted rapidly growing population would unleash famine
•Malthus: predicted population will outgrow food supply
•Hardin: believed resources open to unregulated use will be depleted

Case Studies
•Mexico City: It was a city of 22 million people, dependent on exploitinggroundwater. The water table is dropping 6 for every year causing massiveimpacts in infrastructure.
•Bangladesh: In the 1960s, thousands of wells were dug by foreign governmentsand humanitarian organizations to supply fresh water to the people but arseniccompounds leached into the groundwater
•James Bay, Canada: Generating electrical power for, Hudson Bay has resultedin massive flooding. Mercury leached out.
Math Concepts
•Population: Math is seen in populations when scientists try to evaluatepopulation growth, death rates, and the doubling time. An example can be theequation of 70/% growth rate. Connections can be made between differentpopulation terms like doubling time and percent growth rate. Doubling time canbe found with percent growth rate while growth rate can be found with doublingtime seen in the equation 70/doubling time.
•Toxicology: you use math when determining things like the ppm and the pot, orthe dose of a chemical. Finding the LD50 as well.
•Sample: A population of an area has a growth rate of 3%, what's the doublingtime?
•70/.03
