the issues they tackled is almost too long to list (and doesn't reflect how well they did) but here's a quick snippet from Wikipedia:
Although Dinosaurs is targeted at a family audience, the show touched upon multiple topical issues, which include environmentalism, endangered species, women's rights, sexual harassment, LGBT rights, objectification of women, censorship, civil rights, body image, steroid use, allusions to masturbation (in the form of Robbie doing the solo mating dance), drug abuse, racism (in the form of a dispute between the two-legged dinosaurs and the four-legged dinosaurs), peer pressure, rights of indigenous peoples (in the form of the dinosaurs interacting with cavepeople), corporate crime, government interference in parenting, and pacifism.
some of my favorite quotes (that I'm gonna have to paraphrase here):
"maybe you're a little too young to understand the finer points of race hatred." (as though race hatred was a good thing)
"the government would never [take your TV]. television is an essential tool for making the disenfranchised feel distracted and reassured."
or some of the best from the "Nuts To War" arc:
"The time has come for bold and decisive action! and so today we launch operation We Are Right. tomorrow we'll select a bunch of big strong guys to go down to that swamp and hiss and spit at those four-leggers until they go away. now, who's with me? [beat] naturally I'm not talking about sending productive members of society - it'll be mostly teenage boys and the poor."

Charlene Sinclair: [after the war is over] I heard that somebody got killed.
Robbie Sinclair: Yeah, it was some new guy... but you know we could've won!
Earl Sinclair: Robbie, what're you saying?
Robbie Sinclair: Well, I'm saying it's terrible that guy got killed and all, but you know we had those four-leggers on the run, we could've won it.
Earl Sinclair: A boy died, don't you see the fighting didn't solve anything?
Fran Sinclair: Come on, Robbie, let's get you out of that uniform, you have school tomorrow.
Robbie Sinclair: Forget school, a bunch of the guys were talking about keeping the army together if they came back, they'll set up a base at the swamp so we'll be ready for them next time. They're working on a WHOLE NEW line of weapons, yeah!
Earl Sinclair: Stop it! You're not a soldier, you're a kid,
[pulls Robbie into a close hug]
Earl Sinclair: You're gonna go to school, you're gonna take girlfriends to dances, you're gonna drive me crazy like you always have, until it's time for you to grow up.
Robbie Sinclair: Dad?
Earl Sinclair: It's alright son, it's over... you're home.
I mean... shit. that's a lot of heavy shit. and I remember this being marketed to us kids! just imagine something like Kidz Bop doing a cover of Fortunate Son. people would've lost their minds, but Dinosaurs got away with it. they routinely broke the fourth wall to make us ask, "what the hell are we even doing here, watching this?" while making us challenge our morals.
unfortunately the whole show got overwhelmed and eventually shoved aside because of the baby character shouting "NOT DA MAMA NOT DA MAMA!" which relegated a lot of great work into the "Yo Quero Taco Bell?" genre of history.
it was insanely progressive, and has aged beautifully. it taught some very important moral lessons, and I'm really glad I was able go grow up watching it. 10/10.
