The covenent ally us for the fight against the flood as they invade both earth and the Covenent homeworld are attacked by flood because a peice of halo ends up on either Earth or on the covenent home world i cant remember, this all happens towards the end of the game, because that is when everythig starts getting wiped out by the flood, so the covenent finally decide that the only way to survive would to ally Earth for the fight against the Flood, but yet i dont know how they defeat the flood, i havent read that far...
