Many Thailand shrimp farms have been built in mangrove wetlands. Therefore, overall, the ecosystem capital in this particular region has
A) increased because of the investment in this shrimp industry.
B) increased because the shrimp farm decreases the need to harvest wild populations of shrimp.
C) decreased because the value of the shrimp farm is less than 10 of the value of services provided by the intact mangrove wetland.
D) decreased because on average, the shrimp farm provides more valuable services than the original wetland for only 50 years.
Question 2
If the world cooperated and stabilized the atmospheric levels of GHGs,
A) global temperatures would quickly level off within a year.
B) sea levels would continue to rise for hundreds of years because of their long residence times.
C) rain forests would quickly start to recover and regrow.
D) weather would quickly become predictable.

Pocket gophers and ecosystem structure (data from Huntly and Inouye 1988).
