Economics is the study of the allocation of scarce resources. Note that the theories of economics can be applied to any scarce resource, not just traditional commodities. Economics is not simply about profits or money. It applies anywhere constraints are faced, so that choices must be made.
Economists study how incentives affect peoples behavior. Environmental and natural resource economics is the application of the principles of economics to the study of how environmental and natural resources are developed and managed. Natural resources resources provided by nature that can be divided into increasingly smaller units and allocated at the margin. Environmental resources resources provided by nature that are indivisible. Natural resources serve as inputs to the economic system. Environmental resources are affected by the system (e.g. pollution).
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
