>>5002937 (OP)No intervention is important when you're dealing with a fragile ecosystem where stopping an animal from hunting another can have a drastic effect on their population.
In this case, it was justified to break it since it was just penguins getting stuck in a hole and dying in there for no ones benefit.
Yeah sure scavengers benefit from death, but scavengers aren't likely to run out of food as long as the earth spin, and this sort of situation is hardly the norm.
A single action isn't necessarily bad on its own, but humans tend to do stupid shit in bulk, and have a dozen/hundred/thousand/million/billion humans doing the same thing ends up having a significant impact.
