9. 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 Mill: believed decline in resources would force economic growth to slow Jonas Salk: polio vaccine Theo Coulborn : discovered pesticides can effect systems of pregnant women Jenner: produced first vaccine to cure small pox

10. Case Studies Mexico City: It was a city of 22 million people, dependent on exploiting groundwater. The water table is dropping 6 for every year causing massive impacts in infrastructure. Bangladesh: In the 1960s, thousands of wells were dug by foreign governments and humanitarian organizations to supply fresh water to the people but arsenic compounds leached into the groundwater James Bay, Canada: Generating electrical power for, Hudson Bay has resulted in massive flooding. Mercury leached out.

11. Math Concepts Population: Math is seen in populations when scientists try to evaluate population growth, death rates, and the doubling time. An example can be the equation of 70/% growth rate. Connections can be made between different population terms like doubling time and percent growth rate. Doubling time can be found with percent growth rate while growth rate can be found with doubling time seen in the equation 70/doubling time. Toxicology: you use math when determining things like the ppm and the pot, or the dose of a chemical. Finding the LD50 as well. Sample: A population of an area has a growth rate of 3%, what's the doubling time? 70/.03
