We aren't 'fucking' with the way nature works. You're failing to see the big picture here. We are part of what you call 'nature', surely you'll agree with that being a non-believer, so at least you should say 'I think the nature shouldn't fuck with itself'.
But, still, there would still be no 'fucking', seems like a total nonsense to me.
