Let's say it's a GOOD remake.
-birth control episode slightly retooled: heavier focus on the mindless consumerism, point out birth control has uplifted every society that uses it regularly
-Gi and Ma-Ti have a story arc about the wildlife trade
-Wheeler's dad is more explicitly bigoted and Wheeler has a non-preachy ongoing struggle with not copying that behavior because he's a good kid at the end of it
-Kwame is in charge because he's a little older: maybe a park ranger's kid who became a veterinarian or something
- related: all the Planeteers are different ages, to emphasize that environmentalism isn't just for kids. Ma-Ti is maybe 12, Gi is maybe 15, Linka and Wheeler are in their 20s, and Kwame is in his late 20s/early 30s.
-Linka is the daughter of a former Planeteer who went missing. Plot twist: Dr. Blight is her mom. Now we have to find out how she ended up so corrupted.
-Gaia has had other Planeteers before, but they tend to be replaced when they find a specific niche. She needs people who do her missions. The current batch can find former members involved in things like endangered animal breeding, legal activism to reduce pollution, etc. This leads to Kwame having a small crisis: is he doing his best work with the supernatural entity, or should he go back to his wildlife preserve and help his father? But if he leaves, he's abandoning the kids he feels responsible for now, and having already been a Planeteer means he's a target for the villains even if he leaves.
Villains keep their original themes, but aren't 2-Dimensional about it. They have political allies in various world governments and Gaia has lost Planeteers to them before. Maybe a new villain about overfishing? She's kinda sexy and it's not immediately obvious that she is a villain since she speaks eco-lingo and is so friendly and health-conscious.
Honest discussion of barriers to green technology usage, maybe something about the difference between factory farming and small-scale production.
