Final answer:
The TED talk implies that a mix of empowerment and education for women, access to healthcare, and a focus on reduced fertility rates are key to stopping population growth in the poorest areas. These factors contribute to a demographic transition towards sustainable population levels.
Step-by-step explanation:
The TED talk suggests that the only thing that can stop massive population growth in the poorest areas of the world is a combination of factors, emphasized most significantly by the empowerment and education of women. Access to healthcare, improved infrastructure, and focusing on reduced fertility rates are crucial elements in this process. The approach includes societal changes such as increased economic and educational opportunities for women, advances in gender equality, greater knowledge of family planning, and better access to contraception. These factors, when unified, are seen to lead to a demographic transition that results in lower birth rates and more sustainable population levels.
