I remember encountering a similar problem many years ago regarding ecological damage on a saved game's home planet, but the situation is different & much more dire than your's: there was an eco disaster on a home planet on a saved game home planet as a result of being allied to the player. Like any smart Sporian at that time, I ignored the warning & minded my own business, until it was too late...upon loading the game file that had the eco disaster, only 2 cities was left, & everything else leveled into the ground.

In your situation however, I guess that could happen when you skipped the 1st pointless mission where you get to fly your spacecraft into fireworks & get to play around with the biosphere of your home planet...I can recall that for every saved game, there will always be a missing species slot where you must fill it back in using the cargo abduction beam as a part of the tutorial where they teach you how to unload a creature to enhance the biosphere. However, most of the stuff I spew out here is all from rote memory: its been ages since I actually played the game, so you will have to look that up yourself on how to solve your problem.
