Overpopulation occurs when a region's population exceeds its resources, leading to environmental degradation and a lower quality of life. This situation can strain essential services like water supply, healthcare, and education, making it difficult for communities to thrive. As more people compete for limited resources, issues such as hunger and pollution can become more severe. The causes of overpopulation include factors like high birth rates, decreased mortality rates, and migration. In many developing countries, families may have more children to ensure that some survive to adulthood. Addressing overpopulation requires a combination of education, family planning, and sustainable development practices.
