Even natural phenomena such as volcanic eruptions contribute to air pollution when the plumes of ash and gas are emitted, resulting in a haze created by volcanic aerosols. Fine particulate matter resulting from the smoke from bushfires, black carbon or soot, and the ash plumes and sulfuric gases from volcanic eruptions, also contributes to poor air quality, causing severe health effects.
In 2021, the La Soufriere Volcano in St Vincent and the Grenadines erupted, resulting in the ashfall, and sulphur dioxide experienced in the neighbouring countries of Barbados, Saint Lucia, and Grenada. “It was especially awful 'cause you couldn’t even go outside to that point. It was irritating to my eyes. And just breathing it in, I could feel it in my throat” recalled Charlotte Tom from Trinidad and Tobago, a student currently in Barbados completing a master’s in environmental management who experienced the subsequent poor air quality from the eruption. “I like to be outside; I like fresh air. I like to pull my windows down. When something as simple as being outside is a threat to your health, it is kind of depressing. It takes a toll on you in more than one way.”
Air pollution is disproportionately felt by the most vulnerable and disadvantaged, including women, children, indigenous minorities, poor communities, migrants or displaced persons, the elderly, and those with underlying health conditions. An epidemiologist at the Epidemiology Unit of the Ministry of Health and Wellness in Belize, Antonio Hegar tells us that the long-term health consequences of exposure to poor air quality can cause respiratory diseases such as asthma, emphysema, chronic obstructive pulmonary disease (COPD) but also things that you wouldn't normally associate with air pollution. “People are more at risk of developing strokes, blood clots, and heart attacks as the level of air pollution from fine particulate matter increases.”
For many, like these four women, the reality that climate change and air pollution will continue to affect the quality of the air they breathe is sad. “There is not much that you can do because you can't live in a vacuum,” said Paulette. In her dismay, Abigail expresses, “It's a bit scary thinking about what can go wrong next if it is that we don't change anything. It almost feels like it’s still a taboo topic because many people who still don’t know what climate change is or even if they know, they don’t know that it directly affects them.”
Charlotte exclaims feelings of exasperation when she questions, “Who wants to live in a world where you have to limit your exposure to the air that you breathe? We island people are oftentimes neglected when it comes to the global setting. With an issue as serious and urgent as climate change, you would think there should be no alternatives, there should be no debates - it's an existential crisis”.
I wonder what it will be like for future generations if I'm feeling it already. That scares me” says Priyanka. “It doesn't matter where you come from, who you are or what part of the world you live in; you are facing and feeling the effects and especially in Small Island Developing States.”
The good news is that when we take action to improve the quality of the air, we make our environment cleaner, our health better, and reduce the impacts of the climate crisis. Similarly, policies and interventions that reduce climate change and improve environmental conditions have the potential for huge health co-benefits.
Since 2020, much focus has been on actions for climate and health through the promotion of tools to measure the health co-benefits related to mitigation. The AirQ+ tool which quantifies the health burden and impact of air pollution includes a user-friendly mechanism to assess long-term and short-term exposure to ambient air pollution. The tool is being piloted in Trinidad and Tobago and Cuba and other countries, under the “Strengthening Climate Resilient Health Systems in the Caribbean.”
The project is being funded by the European Union and implemented by PAHO/WHO, along with five sub-regional implementing partners including the CCCCC, UWI, CIMH, CARPHA, and the CARICOM Secretariat, and CARIFORUM plays a key oversight role.
