This year’s World Thinking Day theme is Impact. Impact for the Girl Guides and Girl Scouts is all about bringing positive change. Girl Guides Singapore has chosen 2 UN’s Sustainable Development Goals to be the focus for 2018 for all Brownie and Guide activities, Goal 14 - Life below water and Goal 15 – Life on land. As agents of change, we took part in the clean–up at Marina Bay, during the World Thinking Day celebration on 24 February.
