Mobile Suit Gundam: Seed

From the introduction:

It is the Year 70 of the Cosmic Era, which is Gundam Seed's unique calendar. Your decade long stay is defined by escalating tensions between the PLANTs, home to genetically engineered 'coordinators', and the Earth Sphere dominated by so called Naturals, who don't. You arrive shortly after the events of the Bloody Valentine attack on Junius Seven, and ZAFT's deployment of the Neutron Jammers.

You have the power to make a difference, don't you? So put it to good use...
