Which of the following statements provides the best summary of the global impact of industries on the environment during the past century?

Industrial activity expanded greatly over the past century, increasing its effects on air, water, land, and climate. At the same time, governments introduced regulations to limit pollution and other environmental harms. Therefore, the best summary is that industrial impact has grown and regulations limiting that impact have also grown; the other choices incorrectly suggest no restrictions or a simple steady decline.
