What happens if wolves doesn`t exist...
There would be more herbivors.The herbivors will eat more grass, with less grass there will be less rains and less water in rivers.
That means less water for villages that are around rivers.
There would be less population and in the future the ecosystem would break out because all ecosystems need all types of animals and plants to complete the life cycle.
This is a real problem inYellowstone in USA because in the past in Yellowstone wolves were killed because they saw that they were so many and they eat a lot of different species of animals.
The course of the river changes because the wolves disappeared and when wolves came back again the river changed its course.

What would happen if it electricity or technology didn’t exist....
Can you imagine a world with enough electricity, so with enough technology? We depend on them for all and if we don`t have things doesn`t exist, without mention that probably there would we panic on the earth because many people they would be not prepared.
Imagine in a moment you don’t have your mobile phone, electric light, computer, the Internet, vehicle, heating in your house, etc. we know that we depend on technology.
Probably we would get up with the sun or with the sing of a rooster or other birds. We would go to bed when the sun sets. We would cook with wood, we would learn to enjoy natural food. We would wash clothes in the river. We would not use machines. some machines can we use with our hands, but your life would change a lot because we are used to machines, but it will be healthier to come back to enjoy the nature.it will be as coming back to learn to live.
What Would Have Happened if the Volcanoes Hadn’t Existed
If the volcanoes had not existed the atmosphere, the plants even the life would not have existed. Earth would be an uninhabited place like other planets. Why volcanos are important for us is because they are responsible of the first bacteria on Earth which was able to do photosynthesis and as a result of this a little of oxygen appears and then plants grew on the Earth and the amount of oxygen increased and later other forms of life appeared.
But volcanoes not only produce carbon dioxide also volcanoes expand a little bit the Earth because there exist underwater volcanoes that erupt and the lava mixes with the water and forms island when people can live.
The volcanoes have bad things too like the extinction of all that surrounds the volcano or the extinction of the homosapiens, the ashes, the gases that eject because they are harmful and toxic like smoke, also produce problems in aviation and in telecommunications, the lava that flows can destroy anything and can cause a fire and when it is a volcanic eruption it helps to form the Earth.
So that if there weren’t any volcanoes, the Earth would have to be a solid rock without activity.
In my opinion this happens in Mars, also volcanoes had been one factor that influences the development of life.
Nowadays with new technologies scientists study the volcanoes with drones.
