What technological advance in the Industrial Revolution sparked a population explosion?
Medical and public health practices spread to less-developed countries.
Agriculture became mechanized.
Agriculture was introduced.
Antibiotics were introduced.

Agriculture became mechanized, particularly with the introduction of inventions like the seed drill and the mechanical reaper, revolutionized farming efficiency. This not only increased crop yields but also reduced the need for manual labor, leading to surplus food production. The availability of more food supported larger populations and triggered urbanization as people moved to cities for work, ultimately contributing to a population explosion.

Medical and public health practices spread to less-developed countries played a crucial role in enhancing life expectancy and reducing mortality rates. Initiatives such as vaccination programs and improved sanitation made a noticeable impact, allowing populations to grow healthily. As these practices took root, communities that once struggled with disease began to thrive, further stimulating population growth and altering demographics worldwide.
