In recent years, the world has witnessed a surge in extreme weather events, often linked to climate change. Hurricanes, wildfires, droughts, and heatwaves have become alarmingly common occurrences. While the immediate impact of these disasters is evident, their long-term consequences on human health are now coming to light. In this edition of “Green Chronicles,” we explore the often-overlooked intersection of climate change and cancer, shedding light on the health threats posed by these unnatural disasters.
The Unprecedented Natural Disasters of 2017
In 2017, the United States experienced a harrowing series of natural disasters that captured global attention. Hurricanes Harvey, Irma, and Maria ravaged communities, leaving destruction in their wake. Simultaneously, wildfires swept through California, consuming homes and landscapes. These events were unprecedented and devastating, prompting researchers to investigate the potential links between climate change and health.
The Connection Between Climate Change and Cancer
In the aftermath of these disasters, scientists began to examine how people with cancer had been affected. What they discovered was both concerning and illuminating. A growing body of evidence suggests that climate change has far-reaching implications for cancer and its prevention and treatment. Here’s how:
- Exposure to Carcinogens: Climate change-related disasters can expose individuals to cancer-causing substances, known as carcinogens. For example, wildfire smoke contains several harmful carcinogens, including formaldehyde and benzene. As these wildfires become more frequent and intense due to rising temperatures, so does the risk of cancer for those exposed.
- Impact on Medical Facilities: Hurricanes, fuelled by warming ocean waters, can unleash their fury on coastal areas, destroying vital medical infrastructure. Hospitals, clinics, and laboratories that play a critical role in cancer diagnosis and treatment may be incapacitated. This disruption can have dire consequences for patients who rely on timely medical care.
- Access to Cancer Care: Extreme weather events can hinder people’s access to cancer care. Roads may be impassable, making it difficult for patients to reach healthcare facilities. Moreover, healthcare providers themselves may struggle to deliver care when their resources and infrastructure are compromised.
- Preventive Measures Disrupted: Climate change-induced droughts and floods can affect the availability of fresh fruits and vegetables, key components of a healthy diet that can reduce cancer risk. Prolonged heatwaves or storms may discourage physical activity, which is essential for cancer prevention.
Taking Action to Mitigate the Risks
The nexus of climate change and cancer presents a complex challenge, but there are steps we can take to mitigate the risks:
- Mitigating Climate Change: The most effective way to address the health threats posed by climate change is to tackle its root cause. Reducing greenhouse gas emissions, transitioning to renewable energy sources, and adopting sustainable land-use practices can help mitigate the intensity of disasters and their impact on cancer and overall health.
- Strengthening Healthcare Resilience: Investing in the resilience of healthcare infrastructure is crucial. Hospitals and medical facilities should be designed to withstand extreme weather events, ensuring that cancer patients continue to receive essential care even in times of crisis.
- Promoting Healthy Lifestyles: Encouraging healthy behaviours, such as a balanced diet and regular physical activity, can help reduce cancer risk, even in the face of climate-related challenges. Local governments and communities can play a pivotal role in creating environments that support these choices.
Conclusion
Climate change is no longer an abstract concept. Its effects are manifesting in increasingly frequent and severe natural disasters, with far-reaching implications for our health. The connection between climate change and cancer highlights the urgency of addressing this issue. By taking proactive steps to reduce greenhouse gas emissions, bolster healthcare infrastructure, and promote healthy lifestyles, we can mitigate the risks and safeguard our well-being. In the face of these interconnected challenges, it’s clear that action is not only necessary but imperative for a sustainable and healthy future.
