Who is to blame for the lack of fresh air in buildings in the slums?

The lack of fresh air in buildings in slums can primarily be attributed to inadequate urban planning and insufficient infrastructure. Poor ventilation systems and overcrowded living conditions exacerbate the problem, often resulting from socio-economic factors that limit access to resources. Additionally, government neglect and lack of investment in housing and public health contribute significantly to this issue. Ultimately, a combination of systemic poverty, policy failures, and inadequate support for vulnerable communities plays a critical role.
