Blaming a website (I don't use Instagram and I am not a fan of it) for people's generally shitty behavior is stretching it, don't you think? It is absolutely possible to travel respectfully (one can't avoid the plane ride, other than that, sure) - respecting the local people, landmarks, wildlife etc. But many travelers lack this basic decency and common sense - even if Instagram died today, these people would continue to behave the same.
