Automobile
The correct answer is Chemical fertilizer
So why is this answer correct? : Invented by Fritz Haber with help from the high-pressure methods of Carl Bosch in the early 1900s, the aptly named Fritz-Bosch process is a method of directly synthesizing ammonia from hydrogen and nitrogen, making it more economical. This exploded the availability of fertilizer and increased crop yields to support Earth’s growing population. In 1918, Haber received the Nobel Prize for chemistry for this innovation. Today, experts believe this invention made life possible for billions more people.
