Students often learn about important figures in economics only briefly and in passing, yet the content taught in economics courses often comes from brilliant economists such as these.

At the undergraduate level, environmental economics is typically taught as an applied microeconomics course. However, while topics like externalities and common property resources are great for emphasizing efficiency, they don’t always prepare students to consider environmental concerns as part of the broader economy. Incorporating macroeconomics into these courses can help students understand problems that deal with both scale and efficiency, such as how to reconcile economic growth with environmental quality.

Teaching is an honorable, but difficult, job to do. Economics instructors working in higher education must rapidly and thoroughly communicate complex concepts and theories within tight semester time frames, effectively enough that most students will learn the concepts and pass the course.

One of the key features of the global economy is that it tends to grow over time. In fact, that growth has become something of an expectation in the modern capitalist system, where the success of corporations is often judged by their growth, even over relatively short time horizons.

If you're planning to study economics at a Master's level, then you may have the opportunity to pursue a concentration, sometimes also referred to as a major. While rarer, some PhD programs may also offer concentrations, though many are already specialized degrees (or require you to have your own research agenda).
