Madeira is a Portuguese archipelago situated in the north Atlantic Ocean. Months back Madeira experienced a forest fire that spread widely and ended up reaching the main city, Funchal. The fire started due to high temperatures, dehydration of woodland and powerful winds. Wildfire is a part of nature. It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide- a key greenhouse gas into the atmosphere. Fire’s effect on the landscape may be long-lasting. Fire effects are influenced by forest conditions before the fire and management action taken or not taken after the fire. Fires may contribute to temporary changes in air quality. Air quality on a regional scale is affected only when many acres are burned on the same day. Local problems are more frequent and occasionally acute due to the large quantities of smoke that can be produced in a given area during a short period of time. Smoke consists of small particles of ash, partly consumed fuel, and liquid droplets. Other combustion products include invisible gases such as carbon monoxide, carbon dioxide, hydrocarbons, and small quantities of nitrogen oxides. Oxides of nitrogen are usually produced at temperatures only reached in piled or windrowed slash or in very intense wildfires. In general, fires produce inconsequential amounts of these gases that we should not be taking into our systems.
