Why would you expect teens to behave differently from adults? Most people devote themselves to causes that have somehow affected them. Aside from the orphan ads, look at the ads for various anti-cancer campaigns. They're almost always based on how cancer has directly affected that person in the ad, either themselves, or a loved one. Especially the breast cancer ones, which constantly harp on the lost loved ones, or 'who it's for'.
It's why those orphan ads do so well on TV. People like to see a HUMAN face on any suffering (i.e. Prim and Rue represent what is so bad about Panem).

If the MC's just doing it 'because they care', then one assumes they can withdraw their interest just as easily, which kinda takes the...stake out of the drama, often, if it's "all the MC's own fault", so to speak.
Yes, an interest in social justice or the environment will get you through a few fundraisers, or speeches, but if you're looking for book-length conflict, or anything that takes the MC out of their comfort-zone, you're going to need more than just philosophy as a motivator. When the police move in with the tear-gas and the batons, that's when abstract ideology needs to be stiffened by some 'personal' reason.
Unless
that's your story: showing how your character's life and personality have lead them to this cause, and given them such a level of commitment that they will stick with it through the hard bits. (Because it needs the hard bits, the conflict, to
make a story.)
In the real world, this happens, of course, people do all sorts of things for no reason that they can explain, except that 'It's the right thing to do', but fiction is different.
People know it's a story. They know that the writer is pushing the character around, choosing a cause, choosing how deeply the character gets involved. To make it believable, the writer has to make the character's motivation twice as clear as real life. Otherwise, the character is just a puppet for the writer's views.
Ha ha, yes, but:
(a) If Katniss can overthrow Snow's regime, certainly a tale can be told of how some other teen saves our world. It's fiction, after all, and there is not need to be realistic.

But if most books (and movies) dealt with social issues, don't you think it might affect how the viewers and readers of those media thought and acted?
Maybe not 'realism' but 'verisimilitude', the
appearance of reality.
Yes, it might affect readers. They might stop reading entirely. If all that was available when I was that age were books that were trying to teach me to be a better person, I'd have taken up knitting.
If the point of your writing is to suck people into dealing with social issues, why write fiction? People have expectations for fiction. They want it to make sense, to be able to believe in what they're seeing, to follow an interesting story. If you're reading
non-fiction, it's easier to accept that 'this is just the way it was.'
Why make up YA characters? Find actual young people involved in these social issues, and write about them. Why did they get involved? Why this particular cause? Show their passion. THAT will get more YA readers involved than a made-up story, sounding suspiciously like an educational pamphlet.
Insensitive as it may sound, I really don't care what fictional characters care about. I don't want to read about the effects of war or whatever. My friends are social justice warriors; I get enough of that on my tumblr dashboard.
This is one of those things where reality is unrealistic, I think. If the main character joins an altruism club "just because they care", I assume they've got ulterior motives. Sure people in real life join for that reason, but if it's not related to the plot, what's the point? It's like the author is just adding it in so they can have a moral at the end of the story.
This ^. A story should 'make sense', should be plausible and understandable.
Off your topic, but instructive: Look how many people complain about 'insta-love' or characters falling in love for
no plausible reason. In real life, we all know people who get into relationships for the stupidest reasons or no apparent reason at all. But, in fiction, we want plausibility.
It's the same with devotion to anything, we want to
see why.
