Just remembered this true story and I think details are available on the internet: There was this shepherd in the south of France who started as a young man to plant acorns where ever he went with his sheep. He pressed a little hole into the barren soil with his staff and put an acorn in it. That was all he did but he planted thousands. It was almost barren land in the days he was young. The oak trees grew and in his lifetime he saw many of the acorns growing into trees and in this dry area where he walked his sheep, finally, with the help of the oak trees, little streams and rivulets appeared and the former barren land converted into a lush, green forest. He saw this in his own lifetime.
He had herded his sheep all his life, never went into pension and about 3 days before he died, he went to a monastery and asked the nuns to let him die peacefully in their care. And he did die peacefully. God blessed his soul.
