What is the best explanation for the changes in population and steel consumption during the last 50 years on the graph? (1 point)

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

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

People have grown to understand the effects of consuming too many resources and have used less steel in their daily lives.

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