The main topic of 2015 World Water Day is “Water and Sustainable Development”. Because of the shortage and the unequally distribution of usable water worldwide, the need of educating children and teenagers for protecting/well-treating water source is indispensable. Hsinchu City Sun-Fun Scouts Group, a community-based scout group, will take a real action and have a green conservation campaign on the World Water Day (March 22, 2015). Giving “green” back to the earth by planting trees is the most environmental friendly way. The topic of the World Water Day campaign is “the irrigation channels and the wetland”. More than 100 scouts and volunteers will participate this program, and more than 100 native trees of Taiwan will be planted at that day. Touchein River played an important role for water supplying in agriculture, industry, and urban development in Hsinchu.
