This year marks the 100th anniversary of the outbreak of World War I. Veterans Day, still called by its original names Armistice Day and Remembrance Day in many parts of the world, was created to celebrate the end of that unprecedented conflict, which took place on the 11th hour of the 11th day of the 11th month in 1918. One project in the U.K. wants to commemorate the sacrifices made by millions during that time by planting four Centenary Woods across the country. What an amazing example of the healing power of trees!
