Overfishing is a problem that has become more acute as global populations have increased, technology has improved and the environment has degraded. Until recently most management efforts have focused on limiting fishing days or areas, yet fishing stocks have continued to decline precipitously.

Exit polls are surveys conducted as voters leave their polling place on Election Day. Reaching voters at that moment is important because it overcomes the problem pollsters have conducting telephone polls: people tend to misreport whether they voted or not. The “who won and why did they win” coverage on election night, of course, comes mainly from these exit poll results.

Humans have been working to increase crop yields since agriculture began, and major advances were made during the “green revolution” that began in the 1940s. Genetic engineering has been portrayed as the latest step in this process.  The majority of approved engineered seeds are aimed at decreasing losses due to pests and weeds; a primary example is Bt corn, produces a bacteria that kills the European corn borer and other insects.
