(T/F) Eutrophication can be defined as a population explosion of corals.
False (population explosion of algae)
(T/F) Hazardous waste (such as PCBs) can be legally burned in the incerators built to burn household trash.
(T/F) The maxmum sustainable yield of a resource is the greatest harvest level that will not deplete the resource.
(T/F) Fossil fuels are non-renewable energy sources.
(T/F) Since cholera is spread by contaminatd food or water, people in Pohnpei who got the disease must have encountered the pathogen in this way.
(T/F) Ordot dump is an example of a sanitary landfill.
(T/F) Alternative energy sources for Micronesia include solar power.
(T/F) Leachate can poison our food supply by increasing concentrations of poisons in the food chain.
(T/F) Hazardous wte includes only radioactive wastes (such as those from a nuclear power plant).
(T/F) Point source pollution is generally easier to prevent than non-point source pollution.
True (since you can identify the polluter).
(T/F) The greenhouse effect is the same phenomenon as global warming.
(T/F) If global warming continues at its preset rate, some coral reefs will die.
(T/F) Risk assessment is something best decied by scientists based only on scientific data.
(T/F) Burning trash at low temperatures (such as the recent tire fire at Ordot) can produce dangerous chemicals that we should not breathe.
(T/F) Indicator bacteria (such as E.coli) are very likely to cause serious diseases in people who swim in contaminated waters.
False (stomach ache, rash)
(T/F) If organic waste has a higher biochemical oxygen demand, then it will use up more oxygen when bacteria decompose the waste.
(T/F) In order to sustainably harvest tuna, we need to know both the population size and the population growth rate of the tuna.
(T/F) The "Tragedy of the Commons" can only be prevented by private ownership of a resource.
(T/F) Most ecologists favor re-use of resources (such as paper) instead of incineration of such trash.
(T/F) Sustainable development usually occurs if we exceed the maximum sustainable yield of a resource.
Examples of renewealbe resources include:
a)aluminum ore

a)primary treatment
b)secondary treatment
c)tertiary treatment
d)quaternary treatment
The "Tradegy of Commons" occurs whenerever:
a)conservation by individuals lead to sustanaible resource use
b)government regulation produces conservation
c)conservation by individuals does not protect the resource from depletion
d)each family owns part of a resource (such as a reef)
High levels of coliform bacteria in ocean:
a) mean that our sewage treatmet plants are working
b)are not a reason to close beaches to swimmers
c)mean that we are "swimming in sewer"
d)mean that cholera bacteria are also present in the water
Negative ecological effects of global warming include:
a)death of animals that tolerate higher temperature
b)sea level rise of 1-1.5 fet in the next 100 years
c)a higher rate of coral reproduction
d)more sharks in the ocean
