It seems that it can. I myself get tender pimple-like spots on my cheeks after eating salmon, and have decided that I shall quite eating salmon. It is likely that the fish (most often cultivated) has too many contaminants, and probably depending on what animal feed it has been fed and grown on. Ask around, and you will find many persons have attributed their rash to a marinade or sauce when it is in fact the salmon itself that is the culprit.
Nothing will happen to someone eating ice except urinating alot. However, eating ice is a sign of an iron deficiency.

Grizzly bears are opportunistic feeders and their diet primarily consists of plant material, insects, and smaller animals, with a preference for high-fat foods like salmon during spawning season. While they are capable of eating human remains if they find them, they do not specifically seek out humans as a food source. Human encounters can lead to dangerous situations, but grizzly bears are more likely to avoid humans when possible. Overall, it's not accurate to say they "like" eating humans, fat or otherwise.
The planet? Likely it would recover from human destruction eventually.
A "jack salmon" is actually a pike like Perch fish, not a salmon at all

Salmon is an angle of god.

When the group people who are subject to some authority feel that their fundamental human rights are being usurped the rebellion is likely to happen in the society where these people are living.
