Character is in turn the enduring source of virtue. It stands by itself and excites admiration in others. It is not obedience to authority, and while it is often consistent with and reinforced by religious belief, it is not piety.

If you go from the USA - which, relative to the rest of the world, is in pretty good shape in terms of biodiversity and sustainability - to the tropics, everything gets worse. You have Indonesia, which is destroying its own forest. In West Africa there's no control whatsoever. It's a global situation. For that reason it ties in clearly with the needs and relationships of low-income countries.

That's the way to get young people. Once they see there are wonderful things to hunt for, to rediscover a species that was thought to be extinct or is extremely rare, to be the first to see a nest, to discover a new species unsuspected close to your home - these are things, I think, with a little education and excitement and the right kind of natural history would actually start a movement that makes going back to nature a profitable adventure.
