Short Answer: Because the trees can't stop s-🎵hakin' it off! 🌳🎶

Explanation: The forest is so noisy because the trees are constantly swaying and rustling their leaves, as if they're dancing to their own beat. Just like Taylor Swift's catchy song "Shake It Off," the trees in the forest can't resist grooving to nature's rhythm, creating a symphony of sound. So, next time you're in the woods, remember to join the party and dance along with the noisy forest! 💃🌳🎉
