something
we need to go to mars because when there is to many people on earth we can live in mars as well
oxygen
to live on Mars you would need Oxogen, water, food, and lots of sun tanning lotion because Mars is very hot!
it is possible to live on Mars but to do this you would need an atmosphere, and to have an atmosphere you need gases. To make these gases (there have been discussions about this) you would need to build factories to give off green house gases and make an atmosphere, because Mars is extremely cold at night, then we would have to get people to Mars. This would cost billions and would take a long time to build the atmosphere.
Oxygen
with oxygen water and food you could live in a green house on mars if you can build one
