He's just deemed crazy, however, because no colonizations are prepared anywhere near that sector and he has no proof, the device shooting off into time when the Research Ball Celebi's in breaks (it's not designed like Pokéballs, thus not as durable) and it takes the device. He's kicked off the project, but then, 151 years later, the Earth freezes over and Sinumonas is declared an emergency colonization planet due to it's habitability to humans...
Basically, it's the complete life of the Human Colony on Sinumonas. It's a moral based story, looking at the Pokémon World we accept as the norm through the eyes of someone who's from before then and thus finds it somewhat barbaric. It's also to show why time travelling (at least in the Travelsverse) is fine: because it's always what's intended to happen in the first place.
