>Is there an animal, other than humans, which has a more profound impact on its environment than the beaver?
Pretty much every animal on earth when their population gets out of control and left uncheck. Same with insects. Just to give you an idea, not long ago researchers and astronauts monitoring earth through space with satellite images noticed strange patterns in certain locations around the world when viewed from space. One location deep inside a rain forest(I can't remember the location), they noticed weird circular patterns forming. Researchers expected something man made because of how perfect the circles were and how they only recently, at the time, showed up and would eventually send a team of experts to go check it out on foot.
As they got there they noticed the area was like a swamp with a lot of grassy plains and the circles were giant grassy hills. When they dug up the hills is when they found out it was noting but a pile worms underneath and the giant grassy hill was just a giant pile of worm poop with grass and moss growing to make it look like a grassy plain. The reason being was that it was the perfect location for the worms as it hid them from their natural predators so they were able to live and breed unchecked under giant piles of poop that was big enough to form giant hills that can bee seen from space. The size of the worms were fairly large too just add more proof that they've been living long healthy lives.
People who say humans fucked the planet don't know shit about what animals and insects can do when left unchecked.
