Tree Planting

What's the big deal in planting trees? These royals go around parading their faces in tree-planting ceremonies. Planting a tree is easy. It's the anehs, uncles and the pakciks who water them and care for them and not just one or two months, maybe for years. But nobody mentions the hard work THEY've put in. All the papers do is talk about how noble some royalty is to get their hands dirty to freaking dig a hole and stick a tree in the ground. What's so difficult about that?
