Question

attributed to the industrial revolution as humans figured out how to mass-produce food and resources. this rapid growth differs from historical stability and raises questions about sustainability and environmental impact.

historically, what contributed to the zero population growth of humans?

environmental resistance and biotic potential
abundant food supplies everywhere
no clean water sources
lack of diseases that affected humans

Explanation:

Zero population growth occurs when factors like environmental resistance (limiting factors like resource scarcity, predation, disease) and biotic potential (a species' reproductive capacity) balance. Abundant food (option B) would likely increase population, no clean water (option C) and lack of diseases (option D) don't align with zero growth logic as they'd limit or not limit growth in ways inconsistent with historical zero growth drivers.

Answer:

A. environmental resistance and biotic potential
