Question

question 4
which part of the population is more likely to face and suffer from environmental health risks?
we are all equally impacted
only those who live in urban areas or lower - income countries are affected by their environment
unhealthy environments only affect the very young or very old.
people of lower socioeconomic status.

Explanation:

People of lower socioeconomic status often lack resources for clean living environments, access to healthcare for prevention and treatment of environmental - related health issues. Urban areas in higher - income countries also have environmental health risks (so the option about only urban/lower - income is wrong). And not all populations are equally impacted (refuting the first option). Unhealthy environments affect a wide range of people, not just the very young or old (refuting the third option).

Answer:

People of lower socioeconomic status.
