Possible answer to greenhouse gasses

What we need to do is pollute mars to the extreme level, so an atmosphere will form and sunlight will be trapped inside. Then we'd need vast fields of genetically engineered plants to turn the Co2 into oxygen.

I'm sure these plants have some kind of terrible side effect
