people would safer first nothing world be there
Nothing would happen. Humans ARE animals.
we would all die
There would be less genetic variation in humans
The plant would die. Plants need co2 to make oxygen which humans and animals need to exist.
A volcano has an impact on both the environment and humans. It has an impact on the environment because it would kill all of the plants and scorch the Earth. It would have an impact on humans because if a human civilization lived there, it would wipe out their whole city.
They would die.
There would be an overpopulation of insects
If humans did not exist the population of other animals that we eat would grow because we are not eating them. There would be a lot less damage to the environment as human activity can tend to affect the environment in many ways (such as pollution, cutting down trees, etc.) Also everything would become overgrown and wild animals all over the place.
Someone would have to invent them
we would die
The same thing that would happen to humans if we had no food.
The Fish WOULD NOT SURVIVE
