- (T/ F) The main sewage treatment plants on Guam remove enough nutrients to prevent eutrophication.
- False
- (T/ F) Risk assessment is part of most citizens’ decisions about alternative solutions of environmental problems.
- True
- (T/ F) If a chemical meets the definition of hazardous waste, then it usually will harm both humans and other animals.
- True
- (T/ F) Global warming is the only form of climate change for which good scientific evidence exists.
- False
- (T/ F) Countries want to ban CFCs as quickly as possible mainly because CFCs cause the Greenhouse Effect.
- False
- (T/ F) Sustainable harvesting of Guam’s reef fishes can meet the demand for such fish by all the 150,000 people living here.
- False
- (T/ F) We know that overfishing is occurring, when the fish we catch get smaller every year.
- True
- (T/ F) Sea level rise is only a problem for those atolls that expect to be underwater when the ice caps in the Arctic and Antarctic melt.
- False
- (T/ F) It is easier to overharvest a turtle species that first breeds at 20 years old than it is to overharvest a turtle species that breeds at 2 years old (assuming they both have the same number of eggs).
- True
- (T/ F) We will be forced to get our energy needs from alternative energy sources in the next 100-200 years, because most fossil energy sources will not be available.
- True
-
Types of hazardous waste include:
a)hot water released from a power plant
b)chemicals like PCBs, which may cause cancer in humans
c)acid from car batteries
d)pesticides that break down into harmless ingredients after being exposed to - b),c),d)
-
Ways to protect groundwater from pollution include:
a)regulate types of development projects built above the aquifer
b)use the land above the aquifer for a traditional golf course
c)pump water from wells until some brackish water is found - a),d)
-
Possible ways for each of us to help reduce the bad results of the Greenhouse Effect include:
a)turn off the air conditioner in our car
b)use less hairspray
c)buy a car or truck that gets good gas mileage
d)recycle the Freon (CFC) in - a),c),d)
-
Sustainable development in Micronesia can include:
a)ecotourism (nature tourism)
b)"mining" our reef fisheries to support the demand for reef fish in Japan
c)developing a resort like Disneyland in the Rock Islands in Palau
d - a)
-
Alternative energy sources that could be important in much of Micronesia include:
a)heat from active volcanoes
b)solar power
c)wind power
d)coal - a),b),c)
