Mirrors pointing to Mars

in space pointing at Mars. When positioned above earth, such mirrors
could deflect some of the sunlight normally shining on Earth away from
Earth to Mars. This way, perhaps some of the negative effects of global
warming could be avoided or decreased.
Sending our surplus heat to Mars will raise Mars' surface temperature,
which now is well below zero (Mars is about 50 percent farther from the
sun than Earth). Ice appears to exist on Mars' poles and increased heat
will melt this ice. Spaceships have been sent to Mars before. They can
be sent again to spread seeds to grow plants. Plants could be
genetically modified to suit the Mars environment:

Photosynthesis will transform carbon dioxide in the Mars atmosphere
into oxygen. More oxygen in the air would decrease the difference
between cold and warm temperatures (now more than 100 degrees). Plants
could be used for food. In short, terraforming Mars could result in
human habitats built on Mars. Spaceships could sent people to Mars,
thus avoiding over-population on Earth, while plants and minerals could
be harvested on Mars and sent to earth in the returning spaceships.
To start the project, mirrors could be positioned above earth just like
satellites, with solar panels attached. Sunlight will provide the power
to keep the mirrors in geo-stationary position. By deflecting sunlight
away from earth, the mirrors could be helpful in regard to global
warming. Additionally, the power generated by solar panels could be
sent to earth in the form of microwaves, thus providing clean power to
earth. The mirrors could be partly financed for their function as
communication satellites and for GPS location and navigation services.
