Explain the effects of technology, birth rate, and life expectancy on population growth, and predict the challenges that countries may face as a result.

Good morning, Susana!

The effects of technology on population growth rates and other related rates are the most diverse. With the turn of the nineteenth century to the twentieth century, we noticed that the increasing presence of technologies and new scientific advances was responsible for the expansion of life expectancy. The possibility of producing more food also motivated the population growth and, consequently, the number of births. The challenges are also varied, including:

- Maintain and expand the quality of life;
- Offer food for all individuals;
- Fight against epidemics and deadly diseases;

Militarism is the answer.
