Increased building construction likely led to the increase in steel consumption seen on the graph. Steel is commonly used in construction projects due to its strength and durability, so as more buildings were being constructed, the demand for steel likely increased.

Answer 1

Additionally, rapid urbanization and industrialization in many regions around the world have also contributed to the surge in steel consumption. As more people move to cities and industries grow, there is a greater need for infrastructure development such as roads, bridges, and railways, all of which require significant amounts of steel.

Furthermore, advancements in technology and manufacturing processes have made steel production more efficient and cost-effective, making it a popular choice for a wide range of applications beyond construction, including automotive, machinery, and appliances.

Overall, the growth in steel consumption can be attributed to a combination of factors including increased construction activity, urbanization, industrialization, and technological advancements.
