"Steemit Engagement Challenge S11/W1 - Perhaps if man had not invented fire, what would this earth have looked like?"
Hello all steemian friends
Greetings from me to everyone who reads my post this time, and this time I will write a Steemit Engagement Challenge season 11 week 1 contest, the theme I will raise is "Perhaps if man had not invented fire, what would this earth have looked like?" made by the Hindwhale Community community from the account @hindwhale with some questions asked:
Perhaps if humans had not discovered fire, what would the earth be like? |
---|
Fire is a fast chemical reaction (oxidation) which takes the form of three namely heat, oxygen and combustible material which produces heat and light.
The world today is perfect creation. Including the presence of the element Fire, then if there is no fire on the surface of this earth the world will not be perfect, cold pairs with heat because our bodies will not withstand the cold temperature especially when there is no light of photosynthesis, if suddenly there is no fire that was there then everything will freeze Of course, you can imagine what could live and if there was no fire on earth, humans would not eat cooked food because fire has always been used to cook food. Even though there is electricity now, and there are also no fields available, even if there were any it might take longer for the villagers to cut down all the trees. And also the unavailability of gas.
How do you think humans discovered fire? |
---|
We use fire for the purposes of everyday life. For example, for cooking and heating the body, according to science, fire is the rapid oxidation of a material in an exothermic chemical process from combustion, so because of eternal energy that cannot be created and destroyed by humans, fire cannot be made and compiled. Fire can only be generated by igniting a fire which triggers a reaction releasing heat energy, light, and other products so that it becomes a substance that is a hot yellowish-red color, And humans first discovered fire during the time of ancient humans where at that time they survived by gathering and hunting, and humans first discovered fire 400,000 years ago and according to my knowledge what I know at first pai was known by seeing volcanoes erupt, seeing natural phenomena such as lightning. One time when ancient humans were making tools from stone, the friction of stones with one another turned out to cause sparks. Then the two stones that are rubbed are placed on the dry grass, the sparks from the friction of the stones that burn the grass are what produce fire. That is the history of humans discovering fire for the first time
What are the advantages and disadvantages of fire? |
---|
Excess fire
- there might not be a forest fire
- News circulating about forest fires that may take lives may not happen
- Habitats for rare animals may still exist because a volcano did not erupt which released fire larvae, causing many animals in the forest to become extinct.
Lack of fire - Can kill or injure unwanted plants/trees
- Fire can damage the ecosystem i.e. forest fire can completely destroy the ecologist if not controlled, for example animals, insects, soil and water in the area can be affected and negatively from this consequence.
Is fire important to us or not? |
---|
Of course, fire is very important for us, one of which is its use for cooking, namely burning meat to make it more delicious and safe for human consumption. And also the presence of fire can produce light as a by-product. To make artificial lighting in their homes, people have used fire for thousands of years, and to light pathways to destinations at night. And fire can also help purify water, namely by boiling water for 5 minutes is one of the best ways to clean tap water in our homes so that we can drink water safely and healthily.
How should we handle fire for a safe environment? |
---|
In managing fires for our environment to keep it safe and secure, one way is not to throw away cigarette butts carelessly. Many of us find people throwing cigarette butts carelessly that have not yet extinguished so that they start fires and also by monitoring campfires when camping, both in the forest and anywhere because if it is not monitored, there is a fear that the fire will continue to spread so that fires can occur too, And the burning is done by humans who are not guarded so that the fire also spreads very quickly

Fire indeed plays a very necessary and important role in us. The importance of fire in the kitchen is immense for human life. There are many people in the world who work near fire and they must use safety. Very nicely presented thanks for sharing.
yes, it's true that fire is indeed an important role for humans, even when we cook we need fire, thank you for visiting my bowl
