英语词汇arbor day的起源、历史背景-英语词源词典

词汇	arbor day
词源	Arbor Day. “Tree Day” is the exact meaning of Arbor Day, for arbor is a Latin word for “tree.” Arbor Day was first cele- brated in 1872, when Nebraskan J. Sterling Morton and his supporters persuaded their state to set aside April 10th for tree planting, to compensate for all the trees Americans had de- stroyed over the years in clearing the land for settlements. More than a million trees were planted on that first Arbor Day alone, and today the holiday is celebrated in every state.
