Dinosaurs would evolve, again. They would invent really big internal combustion engines, and use dead humans for fuel.
what would happen is that the animal species would become an invasive species and they would eat all of the plants and food sources, which would starve out animal and human resources, which then would die out animal and human species, and without them, the plants soon will die out, which then they're would be nothing to take care of the earth.
Without boys and girls on Earth, reproduction through sexual reproduction would not be possible, and the human species would not be able to continue through natural means. This would have severe consequences for the survival and evolution of the human race.
all human and animal activity would die
The human race would not be far from extinction.
Seeing as how we humans live on earth, I am not sure what you mean.
No one really knows what would happen because humans have never seen that first hand in reality. But I would imagine that the Earth would look similar to Mars.
then it would hardly have vegetation and human life would not exist
The temperature on Earth will become so hot that no living animal, human or plant could survive.
Fish would die. There are species of fish that live off the algae.
"Earthling", or, since it would amazingly impossible for an identical human species to form somewhere else in the universe, "Human"
In reality, the interior of the Earth is slowly cooling. In human time perspective, however, this cooling has no impact.
Human life on earth would change dramatically. A LOT of people would die and the rest would undergo severe hardship!
