As OC said, Disney or Pixar are not automatically special. Most corporations sponsor some conservation projects as corporate responsibility. Many pick endangered animals as logos.
For an animation to help it should: portrait facts accurately, talk about a real conservation issue, direct people to it and contribute to it.
For now, the main request to the business, as others say too, is accuracy. If an animation messes facts about real animals (but also history or society), thousands of people will take it as truth. For many, it will be the first contact with the topic. Children understand some obvious fiction, but don't confuse them about something important they don't know and could take for reality.
Good thing is that animals are always interesting for people. Biodiversity is so rich that whole species and topics are still untapped by media. I could pick many incredible animals and nature locales for next media franchises. Animation companies can benefit from it even with strong commitment to accuracy, directing people to conservation and sponsoring media projects.
