When you join to independent clauses with a conjunction you stablishes the equality in this clauses, however in this case you can see that the clauses have a causal relation, it could be said If you don’t hold my hand, I will drown, in this case the best conjunction to put the clauses together is “or” “Hold my hand or I will drown.”
It is pathos because on top , it is saying “ save paper- save the planet “, which could indicate that if we do not save paper, we could eventually damage the planet even more.
