Step 1
Cause of Over-Population
Answer
One significant cause of over-population is a decline in mortality rates. Advances in healthcare, sanitation, and nutrition have led to reduced death rates, particularly in developing countries. Vaccinations, antibiotics, and improved public health policies mean that more children survive into adulthood, increasing the population size. For example, in countries such as India, the implementation of vaccination programs has dramatically decreased infant mortality rates.
Step 2
Effect of Over-Population
Answer
A primary effect of over-population is environmental degradation. As more people inhabit an area, the demand for land, water, and food increases, leading to deforestation, overfishing, and pollution. For instance, in Indonesia, rapid population growth has led to extensive deforestation for agricultural purposes, endangering biodiversity and contributing to climate change.
