I would say "Interesting, but I can't wait to go back home."

Intersting question. Me? I would feel really fucking depressed, sad, upset, unhappy and very very fucking disappointed as I realize how much potential humanity really really had if only they were more tolerant of each others differences and had been more willing to put aside any and all of their egos and selfish intetests as well as being much more loyal and honest and transparent throughout with each other. But they never could be really be united, not completely ever united. At least not until there is a common and great external antagonistic force that would make them realize it and reconsider their priorities and all of the various prejudices and discriminations, and hatreds and grudges that they always had for each other. And now they've seriously compromised the integrity of their own planet's resources and ecosystem and jeopardized the welfare of everyone and everything's future on their very planet.
I'd make note of it and report back to my superiors on my planet. I'd tell them, we'll have to standby and wait it out and let them figure it all out and either fail repeatedly and either eventually realize what they had done wrong and learn. And if they never learn, and if for any reason they finally possess the means and resources to travel to other planets and colonize them, then we can NOT allow them to ever reach our planet in any possible way as they would only violate our planet's sanctity with their corruption and impurity. We may have no choice but to consider and implement the least desirable outcome and solution should they ever locate our planet and possibly invade us and steal resources from our planet.1
