Perhaps if man had not invented fire, what would this earth have looked like?

No fire = no electricity, no cars, trains, planes or ships, no cooked food, no air conditioning, no heating. Thousands of years ago our earliest ancestors discovered fire. If they have not done this then we could not lead our life such easily. today we are living in one such modern age because of their descovery.
If fire had not been discovered, the world would not have been what it is like today. One of the tremendous and revolutionary inventions of the world is fire. If there weren't discovery of the fire, it is very possible that no animal would have survived on this earth, particularly the human race. Or there would have been a w new kind of human race. Without fire, we wouldn't have metalwork. Perhaps, it will be horribly different. In fact, we could not have evolved into the species we are today.

How do you think man discovered fire?

Our ancestors discovered fire and managed to control it thousand years ago.

According to Harvard anthropologist Richard Wrangham, "hominids advanced as humans through the discovery and control of fire. He considers this period to be somewhere around 1.8 million years ago." Homo erectus is considered to be the ancestor of humans who lived on earth 1.8 million years ago.

According to that famous anthropologist, Homo erectus is believed to have invented fire. Anthropologists differ on who invented fire first and who controlled it. There is also much debate about these facts. But it seems to me, after the fire was created naturally, man brought the fire under control and man started using fire for many purposes but at that time we had to depend only on nature for fire. Then gradually people created fire by rubbing rocks against rocks and that's how fire was discovered I guess.

What are the advantages and disadvantages of fire?

---

One of the major advances in human civilization was learning the use of fire. While the use of fire has made human life much easier and better, it also has some dangerous aspects. Actually everything has some positive and negative aspects. Let me now highlight its positive and negative aspects.

The advantages of fire

---

• After the discovery of fire, humans were protected from wild animals and still fire is used to protect humans from various dangerous animals.

• We cook raw meat with fire and eat it. By eating boiled meat we are saved from many types of diseases. Raw meat contains various types of bacteria, viruses which are destroyed by fire.

- If fire had not been discovered, we would not have survived in colder countries or at the North Pole. As a result, a part of the world was always left empty.

• Fire is a source of light. Fire is used as a guide in the dark.

• Fire is used for self defense. Fire is also used to clear land and destroy garbage by burning different types of waste materials.

The disadvantages of fire

---

• Fire has many destructive aspects. One of which is that it spreads very quickly. Accidental fire destroys everything in an instant.
• 80% of the world's oxygen is supplied from forests, but they are almost destroyed by fire, which increases the lack of oxygen in the world.

Is fire essential for us or not?

---

Yes fire is essential for us, for the earth too. We cannot even think a single day without fire. If it were not for fire, many people on earth would die and they might not know why. We cannot even see many germs that fire destroys right behind our eyes and protects us from those harmful germs.Man has been able to become such an intelligent creature because of the presence of fire. The presence of fire helps people to relive many hardships and that nutritious food helps in the development of the human brain. So it goes without saying how important fire is in our lives.

How should we handle fire for a safe environment?

For a safe environment we need to handle fire properly. Many use fire for destructive purposes. In the past, fire was used on the battlefield to burn the enemy, which cost many lives.
We should be aware of the use of fire so that the fire we use does not destroy the habitats and shelters of other animals and does not cost the lives of any animals.
We can also keep the environment free from pollution by burning the garbage in the environment with the help of fire.

I would like to invite my friends @jannatmou @sohanurrahman @aaliarubab to Participate in this contest.
