Answer to Question 1

ANS: D
There are many factors working against the mining of methane hydrate. Although it is the biggest
source of hydrocarbons on the planet, it is uneconomical at this point. Methane hydrate is thought to be
responsible for some of the ancient climate change events. Information can be found in the section
Stars and Seas.



Answer to Question 2

ANS: C
The National Marine Fisheries Service estimate that so many fish have been taken that there may not
be enough of a breeding stock left to replenish the populations of these overfished species. Information
can be found in the section Biological Resources.
