A description of an important trade-off associated with the use of nets and fishing technology by fishermen includes the fact that:
(1) many fish can be caught at one time but fish that are not meant to be caught are often killed.
(2) using nets is efficient, and many fish can be caught at one time.
(3) some fish that are not intended to be caught are killed, and some are in danger of extinction.

Part 6

Our [Nitrogen] Fertilized World
It is the engine of agriculture, the key to plenty in our crowded, hungry world. … …Enter modern chemistry. Giant factories capture inert nitrogen gas from the vast stores in our atmosphere and force it into a chemical union with the hydrogen in natural gas, creating the reactive compounds that plants crave. That nitrogen fertilizer – more than a hundred million tons applied worldwide every year – fuels bountiful harvests. Without it, human civilization in its current form could not exist. Our planet’s soil simply could not grow enough food to provide all seven billion of us our accustomed diet. In fact, almost half of the nitrogen found in our bodies’ muscle and organ tissue started out in a fertilizer factory.
Explain how the building of factories to produce fertilizer is an example of a trade-off.
