On a certain day, month and year one should observe the ceremony of tree-planting. Thus, one fulfils one's responsibilities, serves one's fellow-beings which not only brings happiness but benefits all.
Dalai LamaThe problems we face today, violent conflicts, destruction of nature, poverty, hunger, and so on, are human-created problems which can be resolved through human effort, understanding and the development of a sense of brotherhood and sisterhood. We need to cultivate a universal responsibility for one another and the planet we share.
Dalai Lama
