The trees were the worst loss and damage

"The trees were the worst loss and damage, for at Sharkey's bidding they had been cut down recklessly far and wide over the Shire; and Sam grieved over this more than anything else. For one thing, this hurt would take long to heal, and only his great-grandchildren, he thought, would see the Shire as it ought to be."
