The sky in Borneo is thick with smog, not rain, as toxic smoke from uncontrolled wildfires blankets the region and spills across international borders. Volunteer firefighters, many of them indigenous Dayak and Banjar people, are working tirelessly to extinguish the blazes, which have burned over 200,000 hectares of forest and farmland since early July. The fires are not only a local crisis but a transnational one, affecting countries like Singapore, Malaysia, and the Philippines with severe air pollution and health impacts.

The fires are particularly concerning because they are burning through Indonesia's vast peatland ecosystems, which act as massive carbon stores. When these peatlands catch fire, they release millions of tonnes of carbon dioxide, carbon monoxide, and methane into the atmosphere—referred to as 'carbon bombs.' Scientists warn that these emissions could have catastrophic global warming implications. Dr. Nisa Novita, a peatland researcher, explains that peatlands are natural carbon sinks, but when drained or burned, they can release stored carbon rapidly, exacerbating climate change.

The health impacts of the haze are severe, with thousands of respiratory infections reported in Indonesia and neighboring countries. Children under five are especially vulnerable, with over 12,000 cases recorded. Professor Susan Page from the University of Leicester highlights the dangers of breathing in carbon monoxide and fine particulate matter, which can enter the bloodstream and cause long-term health issues.

Despite the dangers, volunteers continue their efforts, often working in toxic conditions and facing exhaustion. Dwi Sujatmoko, a volunteer firefighter, says they are putting family and personal life aside to fulfill their duty. 'We're definitely tired,' he says. 'We miss our families, our children, our wives. But for now, all of us are putting those things aside. We're doing everything we can to help deal with this haze disaster because it's our duty.'

The crisis is rooted in decades of land-use changes, including deforestation and peatland drainage for plantations and agriculture. While indigenous communities have been unfairly blamed for the fires, they are actually using traditional methods that are more sustainable. However, the industrial-scale development projects have made peatlands more fire-prone, creating a cycle of environmental degradation.

As the fires continue to spread, volunteers face the challenge of fighting a fire that can reappear after being extinguished. Water shortages and ongoing drought conditions complicate their efforts. 'We also hope rain comes soon,' says Sujatmoko. 'We've spent months away from home... May all the efforts of those on the front lines be a blessing for everyone.'

The situation underscores the urgent need for global action to address the root causes of the crisis, including sustainable land management and climate resilience strategies. The volunteers' dedication highlights the human cost of environmental neglect and the importance of protecting Indonesia's fragile ecosystems.
