Final answer:
Improving economic development and security, educating women, and creating stable government policies can ameliorate explosive population growth in less developed countries, leading to a demographic transition towards lower birth rates.
Step-by-step explanation:
Ameliorating explosive population expansion in less developed countries can be achieved through several methods. One significant factor is the improvement of economic development and economic security, which typically leads to a demographic transition: a shift from high birth and death rates to lower birth and death rates as a country develops economically. As countries develop, improvements in healthcare such as clean drinking water, improved sanitation, and vaccination significantly reduce death rates, which initially could boost population growth.
However, alongside these improvements, increasing access to education, especially for women, and creating economic opportunities that lead to increased livelihood can lead to lowered birth rates. The availability of food and reduction in infant mortality rates lead to fewer children being born as families require fewer children to ensure survival into adulthood. Furthermore, governmental policies that are market-oriented, investment in health and education, and creation of stable macroeconomic and political environments are essential. These actions attract foreign aid and investment and facilitate a shift towards reduced birth rates and thus, manage population growth in the long term.
