I visited the beach with my grandparents. They had a freakout because my son grabbed a massive branch and dragged it into the sea. Upon questioning them (and them treating me like a bit of a dunce as a result) apparently it's a terrible thing to do because it's littering. Is this common knowledge/actually true? They are really firm in ALL of their beliefs but I swear half of what they say is nonsense. They said "do you ever see wood floating in the sea?" Erm.. Driftwood mate? I also asked what about trees that fall into the sea, apparently they should be removed.
David Attenborough told me that driftwood is a great refuge for turtles and other small creatures and quite frankly, I'm more inclined to believe him.
