Wolves destroying Elk Herds: A Popular claim by hunters as an excuse to hunt wolves and eliminate comptetion with predators. Wolves and Elk have a predator and Prey relationship that stretches back since before the last ice age and before the first humans set foot on the continent. Wolves prey on weak, sick and the old, that way new elk can mate with healthier and stronger elk. When wolves were reintroduced in yellowstone in 1995, the whole ecosystem changed, bushes and aspen trees grew back and beavers had more wood to build their dams. Interestingly enough, Statistics show that mountain lions kill more elk than wolves do, since a single mountain lion can take down a full grown elk with no problem.

Pandas being stupid or evolutionarily failures: No animal is an evolutionairly failure cause that's not how evolution works. And Ironically, people had said the same thing about dinosaurs 100 years ago. No dinosaurs were sucessful animals that survived the planet more than any other species, then they suddenly died out due to unknown causes. And now people are saying the same thing about pandas. If they were evolutionarily failures they wouldn't be here. A lot of people have ranted about them eating bamboo since it has low nutrition. Pandas eat bamboo because it is the most abundant food source in their habitat and it is easy to acess. There's another misleading claim of pandas being stupid: Videos of them seemingly let zookeepers take their cubs which is a false claim by forrest galante. What those videos actually show us are zookeepers persuading female mothers with food so that the panda mother can let them take the cub for health checks. There are tons of videos on youtube saying that pandas are dying and are nearly extinct, some of these contain comments like they're too dumb to survive without humans, and are only alive because of us, none of those make any sense. They have been alive for millions of years since before they were considered endangered.

The Internet is full of misinformation, and sometimes It's best to not believe everything you read on there.

Light behaves differently underwater. It shifts with depth, bends through murky currents, and separates into distinct wavelengths that change from surface to seafloor. For fish, those subtle differences are not just background noise. They are cues.
