Rational people everywhere protect and teach their children as best they can, so those children can go on to have even better lives than their parents and ancestors. The parents may do many things to that end. They may set up a trust, buy insurance or leave the children an estate to benefit their future.
The best estate one can leave is a healthy planet and atmosphere along with all its flora and fauna. A rich environment not squandered for convenience, greed or temporary riches is a truly great gift.
