It costs something like 20 million for a one-person ticket to ride in a space shuttle. Plus months of training. Even if other planets become habitable, then how do we start getting people over there?
And then next, who would even want to go over there? It'd then take hundreds of years for scientists to test everything for safety, record earthquake levels, bring over raw resources, etc.
And I don't think anyone would "prefer" leaving earth. No one wants to willingly leave their friends, jobs, favorite restaurants, fast wireless internet, TV, etc. What do you do when you run out of toilet paper? Fly back to earth?
And what about an economy over there? Who's dollar system would be recognized?
It's just not as easy as you make it sound. Way too impractical. Maybe in another couple thousand years

They're sending oxygen generating plants to mars? Now I've heard everything.

Why not? Is it because you think you would be told that they spent tax dollars for their fun experiments?

We can see there is some kind of seasonal plant growth for sure at the poles maybe our scientists sent them.

There are extreme plants that could live and generate more oxygen in the atmosphere year after year.

"Scientists began to think seriously about terraforming in the 1960s, when Carl Sagan published several articles dealing with the possibility of terraforming Venus. Terraforming Mars has been the major subject of research of two of our panelists tonight, Dr. Chris McKay and Dr. Jim Kasting, since the 1970s."

NASA/DOD did that Satellite-tether experiment in 1992 with the shuttle to study getting rid of the radiation belt by receiving the charged particles and discharging them to Earth's atmosphere. New Zealand protested.

Mars soil capable of sustaining plant life
The Nation
Surprisingly alkaline, it could support green beans and asparagus, 'flabbergasted' scientists say.
A separate recent claim of Martian vegetation came from Carol Stoker and Pascal Ashwanden, both of NASA Ames Research Center, who reported the following at a poster session of the Second Astrobiology Science Conference at NASA Ames Research Center in April 2002:
The Superpan, an image product from the Pathfinder lander camera, is a multispectral panorama of the Pathfinder landing site acquired in 15 wavelengths in the spectral range 440-1100 nm. We have performed an automated search of the Superpan image cubes for the spectral signature associated with chlorophyll. First, images were calibrated to radiance values and then the multispectral images were co-registered to subpixel accuracy. An automated pixel-to-pixel search was performed on a 3-filter set of images (530 nm, 670 nm, 980 nm) to identify pixels where the following condition was met: 530 nm > 670 nm, and 980nm > 670 nm. Thus, we searched for the spectral signature associated with red light absorption by chlorophyll. When this case was met by the search routine, we plotted a full spectrum for the involved pixels and carefully examined the images. The condition was met for small areas in six image cases. All of these cases occur in near field images, where resolution is highest. Four of the cases occur on the spacecraft and appear to be associated with spacecraft structure. Two intriguing cases occur in small areas on the ground near the spacecraft.
