Answer to Question 1

Maximum sustained yield (MSY) is the highest possible rate of use that the system can match with its own rate of replacement or maintenance. The problem with implementing MSY is that we do not know the highest recruitment rate for a species with a specified ecosystem but we make decisions as if we do know. The optimal population size to obtain MSY is one half of the size that it would be at the carrying capacity. We do not know an ecosystem's carrying capacity for various species. Additionally, the carrying capacity will vary from year to year. When the maximum sustained yield is exceeded, the availability of the resource declines.

Answer to Question 2

According to Figure 18-5, there has been a warming trend on both land and in the ocean since 1975 that has not been observed for the past 200 previous years.
