What are forest fires?
Forest fires are a serious environmental problem, as they destroy plant and animal life, cause property destruction, and threaten human safety. What is known about forest fires is that they erupt quickly and spread widely, which makes them a major challenge for firefighting teams and humanitarian efforts, especially since the pace ofclimate changesand human activities has increased. Therefore, in this article, we will discuss the causes of the outbreak of forest fires, their negative effects on the environment, in addition to preventive measures, and possible solutions to confront this environmental disaster.
Spread of forest fires
Forest fires have a huge, uncontrollable combustion capacity, and they occur in forests because of their vast areas of land. Various factors help its spread, such as: dry grasses and wind.
Hence we find – for example – that about one hundred thousand forest fires occur in the United States of America annually, and the occurrence of about 72,400 fires has led to the destruction of about 7 million acres of American land since the year 2000. Also, forest fires in Australia – between 2019 and 2020 – led to the burning of approximately 10.7 million acres of land and farms, and this is equivalent to 107 One thousand square kilometers, in addition to the destruction of more than 5,900 buildings, and the number of deaths was eight people.
Forest fires, also known as bush fires, are large, uncontrolled fires that can completely destroy rural and urban areas. These fires can spread quickly while changing directions suddenly, and they can move long distances when their sparks are blown away by the wind, which increases their spread.
From this standpoint, forest fires can occur due to a variety of natural causes, such as lightning, and also due to human negligence when throwing lit cigarette butts on the ground. The spread of forest fires depends – of course – on the terrain, available fuel materials such as plants and fallen wood, and also depends on weather conditions such as wind direction, speed, and temperature. But the question remains: What causes forest fires?
CausesForest fires
There are many causes that lead to forest fires, and these causes vary between human and natural causes:
First – Human causes
Waste burning:Waste burning may lead to fires in multiple areas, if things get out of control.
Uncontrolled Campfires: Loss of control over campfires is among the most well-known causes of wildfires; Therefore, you must choose a safe place to light a campfire, away from flammable materials.
Lighting cigarettes: Throwing lit cigarettes is one of the most prominent causes of forest fires; Therefore, we must increase awareness among smokers that any negligence may affect the forests and surrounding areas.
Fireworks: Non-adults should be careful when using fireworks, as they can cause fires.
Intentional fires: We should know that intentional fire constitutes 30% of forest fire cases.
Other – Natural causes
Lightning: Lightning can start wildfires, especially hot lightning that lasts a long time. When it occurs, it can produce a spark that ignites a fire in treelands or an entire forest.
Volcanic eruption: Volcanoes erupt burning lava that causes forest fires to break out, as this lava flies and infects everything in its path, especially forests and green areas.
These causes – both natural and human – reflect the seriousness of this environmental phenomenon. So we must understand how forest fires can destroy the human and animal environment and their resources.
What is the impact of forest fires on the environment?
Forest fires are part of various natural phenomena, as they play a crucial role in shaping ecosystems through their work to renew and change. Despite this, these fires can be devastating, as they cause the destruction of homes and the wildlife environment, and pollute the air with harmful emissions that affect human health. The question that comes to mind now is: What are the most prominent direct effects of forest fires, and ways to combat them?
Degradation of ecosystems and biodiversity:Fires destroy the habitat of animals and affect the complex relationships between diverse plants and animals, which ultimately leads to the loss of ecosystems and biodiversity. Forest fires also destroy lands, which can be the only shelter for some plants and animals, and can lead to the extinction of some organisms.
Soil degradation:Forest fires are capable ofkilling beneficial microorganisms in the soil, which have an important role in soil decomposition and enhancing microbial activities in it. This type of fire also leaves trees and soil plants bare, exposing them to erosion.
Air pollution: Trees and plants work to purify the air, which we depend on to breathe, as trees absorb carbon dioxide, prevent dust from reaching residential areas, and then release oxygen into the atmosphere. When fires destroy plants, the quality of the air we breathe deteriorates, and Greenhouse Gases (GHGs) increase in the atmosphere. Which leads to climate change and global warming.
Firefighting methods
It is worth noting that many countries are working hard – in cooperation with natural disaster control agencies and the United Nations – to combat the phenomenon of forest fires and limit their spread. So that it can increase the area of agricultural land, to achieve food security, and increase crop production.
On the procedural level, rapid intervention units are the most prominent means of combating forest fires in developed countries, as these units rely on multiple equipment to put out fires. These equipments include the use of fire-fighting materials – non-toxic salts used to combat fires effectively – and the use of water and drilling equipment that works to remove parts of the forest in order to reduce the spread of the fire and contain it, as well as equipping aircraft with special extinguishing materials to confront such fires.
In this context, countries rely on other strategies to control forest fires, such as: fire brigades deliberately ignite small fires that can disrupt the center of the fire and stop its rapid spread. These preventive and intervention measures all aim to preserve forests as an essentialnatural wealth, protect plant and animal life, and maintain the general environmental balance.
At the conclusion of this article, we are pleased to point out thatEarth Guards Magazine through this article sought to define the term “forest fires” in an easy way, and mentioned the impact of these fires on our environment; It is an article that comes within theseries (What…?), which aims to clarify environmental and development concepts in a simplified manner.
The Earth Guards invite you to take advantage of theseawareness articles, and spread them among friends, family, and the entire community, so that we can work together to preserve the environment; Because protecting the environment is our shared duty and responsibility towards future generations.
