Tradeoffs • - in order to gain 1 of x, must give up some of y • Opportunity costs • -the value of the next-highest-valued alternative use of that resource. • The “cost” of choosing x is to give up y • If, for example, you spend time and money going to a movie, you cannot spend the time and money on something else.

Human population growth increases the need for certain resources, such as food/water • Rise in demand for products can lead to its scarcity in the market (Newest tech gadget / game / Tickle Me Elmo)
