Can you can read the minds of commercial makers

?
Or even:
Do you want to ban anti-smoking commercials because you think that they are "designed to scare children"?
Safe driving commercials often have car crashes - "designed to scare children"?
And why only commercials - is the news "designed to scare children"?
What little we know about that commercial suggests that it was designed to raise awareness of the danger of global warming for at least polar bears in people who can do something about it -
adults. It would be fairly useless to target children.
We know that it presented valid evidence based on science. Global warming will endanger polar bears. Some people are "going to die like that bear" (but not on ice bergs!) since one predication is more extreme weather events.
A danger of home schooling is that it can teach children falsehoods if you have a biased supplier of educational material. Make sure that you do not.
