Now in its sixth year, the charitable(慈善的)day uses the power of social media to encourage organizations and individuals to donate funds or resources to worthy causes. Its mission is to bring positive change to munities through giving. Though devoting just one day to a worthy cause may not seem much, Giving Tuesday makes a surprisingly significant impact. In 2015,ORGANIZE,an online organ donor program asked people to “Give with your Heart”,by being registered donors. Thousands of Americans listen to the cry for help, resulting in one of the largest digital donor drives in US history. That same year, the Cleveland Library and the Pratt Library in Baltimore peted to see who could encourage more donations. While the Pratt Library won with a $41,000 acquisition, the Cleveland Library was able to raise a fairly large amount for its programs as well. In 2016, the University of Michigan encouraged students and friends to donate to hourly challenges. They raised an amazing $ million! The university hopes to recreate the magic this year, with a virtual celebration to mark the institution39。s 200th anniversary. Giving Tuesday is not just a US phenomenon, but a global movement. In 2016, 98 countries participated in the event, raising $177 million, a 44% increase over 2015, when 71 nations collected $ million. These numbers can only increase as the day gains further recognition. Though donating funds is a great way to help, there are numerous other ways to support your local munity. You can give back by volunteering at a nearby nonprofit or food bank. Social media experts can do their share by spreading the information and inspiring their colleagues to get involved. Another great way to celebrate Giving Tuesday is by helping those closest to you, whether that39。s assisting a family member with chores or helping a neighbor with yard work.（1）Why is Giving Tuesday started?
