This relational knowledge is required to coordinate the work of many different specialists. Go back to table of terms . Goods Goods are material objects that the IS needs for some of its important objectives . Those goods that renew themselves or are available in larger quantities than the ISs of a society will need in the future.

Air is a free good, but clean air can become scarce due to contamination.
Game and fish are free goods as long as their populations are much larger than the hunting and fishing community. Minable ores were free goods only as long as the consuming society was relatively small and consumed little.

The IS must manufacture them or obtain them from other ISs through barter or payment.
