The preventive measures for forest fires include some preemptive methods that can help reduce the risks of fires and control their severity and spread, and thus, maintain ecological balance and protect resources. Close monitoring of forest fires caused by natural factors can help prevent their spread to a large extent. To contain forest fires, fire departments usually use water and chemical fire retardants that can be dropped from planes and helicopters. To control the spread of a wildfire.firefighters usually create a control line by removing all fuel from an area so that the fire cannot travel across it.  Controlled burns are often employed by government authorities to reduce fuel buildup, and clean up the fallen leaves, and thus, prevent the spread of forest fires to a vast area. Regular controlled burns can also help maintain biodiversity, as the smoke and heat produced in the process can facilitate the growth of seeds of certain plant species. Apart from these, responsible human behavior can help reduce the number of forest fires to a great extent. In fact, we can reduce the number of wildfires dramatically by not leaving behind any source of fire in the forest.  Forest fires can affect climate and weather to a great extent, besides causing severe damage to valuable trees. Wildfires can increase the level of greenhouse gases (water vapor, carbon dioxide, etc), and therefore increase pollution and global warming. However, they are also an important part of the ecosystem, and many plants depend on the heat and smoke generated by wildfires for their growth and reproduction. But large wildfires can cause extensive damage to the ecosystem, which again highlights the importance of effective control and prevention of forest fires*
