Finance is a field that deals with the study of investments. It includes the dynamics of assets and liabilities over time under conditions of different degrees of uncertainties and risks. Finance can also be defined as the science of money management. Market participants aim to price assets based on their risk level, fundamental value, and their expected rate of return. Finance can be broken into three sub-categories: public finance, corporate finance and personal finance.
Economics is not simply a topic on which to express opinions or vent emotions. It is a systematic study of what happens when you do specific things in specific ways. In economic analysis, the methods used by a Marxist economist like Oskar Lange did not differ in any fundamental way from the methods used by a conservative economist like Milton Friedman.
Thomas Sowell, Ch. 1 What is Economics? in Basic Economics
Pesticides are used around the world but can persist in the environment, contaminating drinking and irrigation water with toxic organic compounds. One example is Vietnam where herbicides and dioxins applied during the Vietnam war entered the water cycle, possibly leading to cancers and abnormalities in newborn babies.
