Known as one of the four elements that are part of nature (along with air, water and land), fire is perhaps the most chaotic of them, being difficult to control and becoming in many cases a danger to humans and even for nature itself. However, it is undeniable that fire is extremely important to man because of all that it allows him to do and all the benefits that it brings him. Although fire exists naturally, one of the greatest achievements of the human being on his way to civilization was to be able to create it by himself through different basic techniques with the aim of being able to use it whenever he needs it and not only when found in nature.
Fire occurs from the oxidation of combustible materials. When we speak of oxidation, we are obviously referring to one of those combustible materials coming into contact with oxygen . This combustion takes the form of flames, gases and smoke and can take place in various forms, mainly by friction or by the existence of a violent reaction.
The importance of fire goes through two main places. In a first point, we can say that by being able to dominate fire, the human being understood that he was superior to the rest of the animals since none of them could do it and therefore the response to the igneous phenomenon was fear. On the other hand, fire became a very precious asset of the human being for practical reasons: it allowed him to cook his food, thus ensuring a better quality of life and less exposure to bacteria , diseases and viruses. In addition, the fire allowed it to shelter from the cold and therefore subsist even more in harsh climates in which before it did not have much protection.
Nowadays, fire is what allows many industries and factories that require this type of combustion to operate, in addition to being the basis of many products, such as petroleum products.
