Hélio da Silva, o plantador de árvores

Looks like his real name (da Silva is the most common surname in Brazil) and nominative determinism: "Sun of the Forest". Silvicultura.

I'm trying to get some trees to grow - it's a lot of work: Hélio has spent huge amounts of time and money on it (average wage might be USD1000/month and article says he was spending 7000 a year and if that was in the past then amount is a lot more in today's dollars).

Typifies the old "you don't plant trees for you but you plant them for those who come after you."
