Hula is very fond to the theme of water, so he is representing the Goal 6 (Clean Water and sanitation) for the project Towards 2030, which aims to secure for everyone the access and the sustainable administration of water and hygienic-sanitary structures. The blue drops are both representing water and tears, underlining the urgency of the problem (water is in fact not available for everyone, causing great struggles). The young face is very emotional, because water is fundamental to life and its lack can affect the life of many.
