colonizing mars? maybe contradictions

combination of magnetism types and their variability define the growth and complexity of living organisms.

compare the complexity of earth and mars. which would have more complex magnetism / gravity?

replanting a complex plant in soil less complex than from its origin, would have a negative impact on the plant's surviveability.

same with replanting humans from earth to mars?

so will elon's mars colony take along the tech to replicate earth's magnetism / gravity?
