What is the best explanation for the changes in population and steel consumption during the last 50 years on the graph? People have grown to understand the effects of consuming too many resources and have used less steel in
their daily lives

Past construction of things like hydroelectric dams has continued to meet needs without requiring more
construction

We are running out of the matenals needed to make steel so there will be less and less used each year

Even though the population has decreased people are using more and more steel each year
