  • Identifying vulnerable populations is crucial, as older individuals and those of lower socioeconomic status are particularly impacted by poor air quality.
  • Neurodegenerative diseases like Alzheimer’s and Parkinson’s have risk factors associated with environmental exposures, including exposure to pesticides and herbicides.
  • Maternal health, environmental risks, and toxic exposures are known risk factors for dementia, highlighting the importance of external environmental factors starting in utero.
  • Researchers are placing more focus on potential links between air pollution and neurodegenerative diseases, emphasising the need for further investigation and action.

Taking Action: Preventing and Mitigating the Effects of Air Pollution

Implementing effective strategies and initiatives, alongside governmental regulations, can help prevent and mitigate the detrimental effects of air pollution on public health.

One approach is the use of air purifiers, which can help remove harmful particles and pollutants from indoor spaces, improving the overall air quality.

Additionally, individuals can make lifestyle changes to reduce their exposure to air pollution.

This can include avoiding heavily polluted areas, using public transportation or carpooling instead of alone, and practising sustainable habits such as recycling and reducing energy consumption.

Being aware of air quality and taking necessary precautions, especially for athletes and individuals with cardiac or lung diseases, is also crucial.

Addressing Inequities: Health Care and Environmental Policies

To effectively address inequities in health care and environmental policies, it is crucial to prioritise the needs of lower socioeconomic status communities and implement necessary changes.

Investing in research and policy changes can help reduce the burden of air pollution on these communities.

Here are some key actions that need to be taken:

  • Increase access to affordable healthcare services for lower socioeconomic status communities.
  • Implement stricter regulations on industries and corporations to reduce emissions and improve air quality.
  • Develop programs and initiatives to educate and raise awareness about the health risks of air pollution.
  • Advocate for policies that promote environmental justice and reduce the disproportionate impact of pollution on marginalised communities.
  • Allocate resources to support the development of sustainable and clean technologies to reduce pollution levels.

Climate and Health Justice: A Call for Change

The call for change in climate and health justice requires a comprehensive examination of the structural inequities and systemic barriers that perpetuate disparities in access to healthcare and the burden of environmental pollution on marginalised communities.

Promoting equality and environmental justice is essential to address these issues.

Lower socioeconomic status and historically underserved communities are disproportionately affected by the negative impacts of climate change and environmental pollution.

Redlining, exclusion, and other policies have contributed to placing vulnerable populations in harm’s way.

To achieve climate and health justice, changes are needed in both the health care system and environmental policies.

This includes ensuring equal access to healthcare services and implementing policies that reduce inequities in health care and disease burden.
