Final answer:
Human domination of the planet has been primarily due to the utilization of fossil fuels, relentless human ambition causing environmental change and species extinction, and the pressures of a large global population.
Step-by-step explanation:
The three things key to our domination of the planet can be seen as follows:
- The discovery and utilization of fossil fuels have been a fundamental driver of technological and societal advancement, enabling the impressive state of knowledge and industrial capacity we enjoy today.
- Human ambition and the drive for continuous growth have led to significant changes in the Earth's environment, altering ecosystems and causing species extinction at an unprecedented rate.
- The sheer scale of the global population puts tremendous pressure on Earth's resources, and managing this population growth is essential to sustainability and planetary health.
The combined effect of these factors underscores the importance of responsible resource management, environmental protection, and sustainable living practices to maintain the balance on our finite planet.
