Adam, I think I know what we can do! We will have to try to destroy it, and if we can't we will have to evacuate the city of Toronto!
Yeah, that sounds like a good idea lets try to destroy it! But... what if it hits Toronto how will we deal with it ?
If it hits Toronto, we will have to try and rebuild the city as best as we can. If there is to much cost in damages to Toronto and our earth then, we will need to move planets which is called terraforming. Our best planet option would be Mars.
Okay sounds good. Let's not worry about that now.
Also if we were to try to move planets we would have to do a lot of work. Such as create a bubble around Mars so the heat from the sun gets trapped in and the oxygen and carbon dioxide needed for life can stay trapped in.
We would also have to change the temperature of Mars when the bubble is formed since it is too cold compared to earth.
