Read the passage below carefully:
Rapid urban expansion across West Africa has systematically converted natural vegetation into heat-absorbing concrete surfaces, creating severe urban heat islands. This thermal entrapment not only intensifies localized microclimates but also drastically escalates municipal energy demands and exacerbates respiratory health hazards among vulnerable populations. In response to this environmental degradation, urban planners are adopting targeted green infrastructure initiatives, including vertical gardens and permeable pavements. Consequently, incorporating these eco-friendly architectural strategies mitigates ambient temperatures while establishing long-term economic and ecological resilience in metropolitan centers.
Which of the following represents the correct logical sequence of the synthesized points to form a coherent summary of the passage from cause to ultimate resolution?
- 1Unchecked concrete development replaces natural foliage, giving rise to localized urban heat traps.
- 2Thermal entrapment escalates energy demands and aggravates public health vulnerabilities.
- 3Urban planners introduce green interventions, such as vertical gardens and permeable pavements, to counter the damage.
- 4Eco-friendly architecture reduces ambient heat and fosters long-term metropolitan resilience.
