3. Forest Fire Prevention
Ironically, lightning can be quite important in preventing more extensive, more catastrophic forest fires; this advantage has great consequences for systems of ecosystem management and wildfire control. Although lightning is usually connected with beginning wildfires, it also helps woods to naturally control fires. The main fuels for bigger, more damaging flames are underbrush and dead vegetation, which little fires started by lightning strikes help nature sweep out. Natural firebreaks produced by these smaller, lightning-induced fires help to limit the supply of combustible material accessible for possible mega-fires. Maintaining the health of forests and limiting the accumulation of too dry vegetation that can cause uncontrollably strong blazes depend on this process, sometimes referred to as fuel reduction. Furthermore, some plant species have developed to depend on regular fires for their life cycles; lightning-generated fires support this natural rhythm. Inspired by this natural occurrence, forest managers and ecologists have included controlled burning methods into their forest management activities since they understand the need of these natural fires in preserving ecosystem balance. Through controlled burns, they can replicate the impacts of lightning-induced flames, therefore lowering the danger of catastrophic wildfires and so supporting forest regeneration and biodiversity. This surprising advantage of lightning exposes the intricate interaction among several components in our ecosystems and questions our view of natural events.
4. Atmospheric Cleansing
As a natural air cleaner, lightning greatly helps to cleanse our atmosphere in hitherto unexpected and useful ways. Strong updrafts and downdrafts are produced when lightning strikes rapidly heating and cooling of the surrounding air. These air currents together with lightning’s electrical charges help to efficiently remove particulate debris and contaminants from the environment. Ionising air molecules ionise pollutants, which then attract and bind to one another, so neutralising them or causing them to descend with precipitation. Particularly useful in eliminating aerosols, dust particles, and some forms of air pollution potentially detrimental to human health and the environment is this natural cleansing mechanism. Furthermore, methane, a strong greenhouse gas, breaks down in the atmosphere in part by the nitrogen oxides generated by lightning. Although nitrogen oxides produced by humans are usually regarded as pollutants, those produced by lightning happen at higher altitudes where they can be advantageous. In tropical areas, where thunderstorms are frequent and strong, this atmospheric cleansing action of lightning is particularly remarkable. Lightning’s cleansing effect serves to reduce some of the consequences of human-generated air pollution and supports the general quality of the air we breathe. Knowing this advantage of lightning has motivated studies on artificial ionisation technologies for air purification, therefore proving how nature’s processes could guide and enhance human environmental technologies.
