Forest fires, also known as wildfires, have become one of the most pressing environmental challenges in recent decades, particularly as the impacts of climate change intensify. Forest fires are not entirely new to ecological systems; they have always been a natural occurrence that helps maintain ecological balance in some forested regions by regenerating soil nutrients, enabling seed dispersal, and clearing decayed vegetation. However, in the modern context, the scale, frequency, and intensity of forest fires have increased dramatically due to both natural and anthropogenic causes, and their consequences have become far more devastating. Understanding the causes and consequences of forest fires is essential for devising strategies to mitigate their impacts, particularly in the face of climate change which exacerbates their occurrence and consequences. One of the primary natural causes of forest fires is lightning strikes. In many dry forested regions, lightning can ignite dry vegetation and set off fires that spread rapidly, especially under conditions of high temperature and low humidity. In some ecosystems, such as certain coniferous forests, fire caused by lightning is even part of the natural regeneration cycle. However, the problem becomes more acute when natural factors combine with human-induced climate change, leading to more frequent lightning events and drier landscapes that make forests increasingly vulnerable to ignition. Human activity is by far the leading cause of modern forest fires. Careless handling of fire in forested areas, such as unattended campfires, discarded cigarettes, or burning of agricultural residue near forests, often leads to the spread of flames into forest ecosystems. Deforestation and logging activities not only destroy tree cover but also leave behind dry biomass, which acts as fuel for fire. The expansion of agricultural land through slash-and-burn techniques in tropical regions further contributes to forest fire outbreaks. Moreover, accidental sparks from vehicles, electric lines, or industrial activities can ignite fires in forests that are already prone to burning due to dry conditions. Climate change plays a significant role in magnifying the risk of forest fires. Rising global temperatures have led to prolonged heatwaves and higher evaporation rates, which dry out vegetation and soil, creating ideal conditions for wildfires. Changes in precipitation patterns also contribute to this vulnerability: while some regions face extended droughts, others may experience sudden bursts of rainfall that encourage plant growth, only for this vegetation to dry out later and become fire fuel. Additionally, climate change is linked to stronger wind patterns, which accelerate the spread of fires once they are ignited. This interplay of higher temperatures, drier conditions, and extreme weather events demonstrates how climate change acts as a catalyst in increasing the frequency and intensity of forest fires worldwide. The consequences of forest fires are multifaceted, affecting ecological systems, human societies, and the global climate. Ecologically, forest fires lead to the immediate destruction of vegetation and wildlife habitats. Trees and plants are often burned completely, leaving behind barren landscapes that take decades to recover. Fires also threaten biodiversity
