The future of the Human Species - Part 3: How do we engi

The process of making an unearthly world more earth-like for the purpose of supporting human life is called teraforming - Steven Wintergerst.

Teraforming Mars is the only way we, humans can live and reproduce thus starting all over again on the red planet. As stated above, teraforming transforms any world unlike Earth into an inhabitable place for humans. Of course we cannot convert another planet, Mars for example, 100% into Earth. However Mars must resemble Earth in the following aspects:
1.Thicken the small existing atmosphere and make it comprise the important gases required for life, in their needed volume.
2.A new magnetosphere should be set up. A magnetosphere will protect inhabitants and every other object on Mars from being beamed with cosmic rays from outer space. All lives are in danger of being destroyed by cosmic rays as they may destroy DNA bonds of common life.
3.Make the temperature more or less similar to that of Earth. As you know, Mars is colder than Earth as the red planet is further away from the sun that Earth is.

Some issues however cannot be changed. The main ones are:
1.Gravity of Mars is much lower than that of Earth. If ever humans settle there, they will have to cope with this. They will use much less effort to move about on Mars. But they will then be condemned to stay there unless they exercise regularly. This is simply because their muscles will become weaker and weaker and smaller and smaller in size. These muscles will not be able to cope with the much larger effort needed to walk on Earth.
2.Mars is dead. They are no forests nor any bush. In fact there are no greens. Mars is forced to remain as this unless we re-melt its core (that
