No, but cows can destroy pine trees by rubbing the bark off, chewing off the twigs and branches, etc. Pine trees are actually poisonous to cattle, especially to pregnant cows.
None of the above. Cows typically make a sound commonly referred to as a "moo."
Chirping is how birds communicate with one another much as how humans talk, dogs bark and cows moo.
Cows are not equipped with vocal cords that are capable of producing barking sounds. Barking is a behavior associated with canines, such as dogs, and is a form of communication specific to that species. Cows communicate using other vocalizations like mooing.
Because they can. It's just like asking why kitty cats meow, puppy dogs bark, humans talk, etc.
