if there were no octopus on earth, the people who catch octopuses and sell them for a living would have have to find another job!Also the person who discovered it would never have if it didn't even exist!
ha ha well nothing would happen because there was no life on earth.
the earth would be destroyed
the earth would die
Earth would stay the same
It's hard to predict the exact impact of any one species extinction. When the ecosystem is disrupted enough, it will collapse and do so quite rapidly. Will the loss of the octopus trigger the collapse? You just never know. At the very least, the people who like to eat, look at, or sell octopus will be effected.
we would be dead
you would be melted
earth would no longer exist
No
Earth would stay the same
oceans would dry
It would be better to ask what would happen if Earth hit a star, as stars are much larger than Earth is. The planet would be vaporized by the intense heat.
