You are so small. So innocent. So beautiful. For you and for everyone else, I will try harder.

Don’t ever let anyone tell you your actions don’t matter. Every single thing you do matters. You matter.

Pedimos que vocês procurem fazer como nós e continuem essa luta de colaborar com nosso planeta: evitando o consumo exagerado, usando a tecnologia para o bem, plantando árvores, economizando água e poluindo menos.

I tried to teach you of the importance of being satisfied with what you had within your hands.

I will keep the air clean so everyone can see the sunset.

I hope, as your father, I’ve done enough to instill within you how science is a wonderful adventure.
