I think sexuality is a highly complicated issue, and there are many influences on sexual choice. People ALWAYS have a choice of what gender they have sex with (or at least to choose not to have sex)-- however, it's possible that one of them will be highly pleasurable, and the other highly disgusting. So the question isn't whether it's a choice-- the question is whether there's a good reason to force people who find same-gender sex more pleasurable than hetero sex to engage in hetero sex anyway.
Really the only really good reason I can think of, and this is just my opinion, is that parents invest a lot in their children, and the main payoff they hope for is grandchildren. Certainly, I would be disappointed if both my kids were gay, and my genetic line was wiped out. And I think ultimately, that's where the "morality" gets stamped on it-- elders generally coin moral rules, and elders generally want to see cute little kids running around but can't make them. Just brainstorming here.
As for overcrowding and pollution-- wow, if there was much more homosexuality in, say, China, that would be nothing but a win-win all the way.
