terraforming of mars

send rockets to mars that lands on the mars equator 

and releases genetically modified micro organisms 

such as algae, fungus and bacteria 

that convert carbon dioxide to oxygen 

and when old micro organisms die then soil is created 

that make new micro organisms thrive in that soil 

later or at the same time send rockets to mars 

that lands on the mars equator and releases robots 

that plants genetically modified grass or small plants 

in the soil created by micro organisms 

or put a seed inside a packet of soil 

and use robots that plants many of those packets in the mars ground 

plants convert carbon dioxide to oxygen 

when micro organisms and plants die 

then that will create soil on mars 

that will enable more micro organisms and plants to grow 

and that will create more soil 

which will enable larger plants to grow on mars 

micro organisms and plants that convert carbon dioxide to oxygen 

could in the beginning enable insects to live on mars 

and possibly later enable animals to live on mars 

insects could make it easier for micro organisms and plants 

to spread on mars 

and old insects that die would become more soil 

the activity of micro organisms, plants and insects 

could possibly slightly affect the temperature on mars 

according to media the temperature of the equator on mars 

is +20°C in the summer and -30°C in the winter 

plants on earth are able to survive those temperatures 

according to media the atmosphere on mars consists of 

95% carbon dioxide 

3% nitrogen 

and other gases 

plants on earth need carbon dioxide for photosynthesis to function

but according to media plants on earth needs oxygen to breathe 

so plants could be genetically modified 

to extract oxygen from carbon dioxide in the mars atmosphere 

possibly by using dna from bacteria and inserting that dna into plants 

if there were native organisms on mars before 

or if there are native micro organisms on mars presently 

then the effects of terraforming of mars on those micro organisms 

should be ignored 

because humanity's colonization of the solar system is more important 

it would be cheap but slow terraforming of mars
