March 12 marks the China's Arbor Day (or the Tree Planting Day), which is a day to encourage people to plant trees. This day was founded by famous Chinese forestry scientist Ling Daoyang in 1915, and it was moved to March 12 in 1929 to commemorate Sun Yat-sen, a politician who did much to promote forestry during his life. Since then, Arbor Day has been a day to encourage tree plating in China.

Trees are silent friends to humans, as it makes its contributions silently. Trees can absorb carbon dioxide and release oxygen to ease climate change. It also cleans the air and cools the city. Besides, trees also provides humans with food and wood. It is an extremely important part of the ecosystem.
