You appear to be a VERY wise parent, too.
Best wishes!!!
I’m a geophysicist, while not the “whole earth” type, still know enough about it (and geology) to know that the earth changes over time. And with no help from us.
I think a large part of why people get sucked into it is their humanistic viewpoint of the world. Man is all powerful, and we have the power to hurt - or save - the earth. One would think that a relatively small event such as Hurricane Katrina would show the fallacy of that.
