I inferred your question to be; Two ways in which the lack of basic services causes major/negative impacts on the health of poor people in South Africa.
Answer:
- maternal mortality
- lowers the life expectancy
Step-by-step explanation:
Lack of basic services refers to the unavailability of essential services (healthcare, clean water, etc) needed by humans to maintain good health.
Maternal mortality: a lack of public health services negatively impacts poor pregnant women in South Africa often leading to avoidable deaths.
Lowers the life expectancy: A lack of basic services leads to underlining health problems that go untreated; thus, reducing the life expectancy of poor people in South Africa.
