June 5 is World Environment Day, also known as Eco-day. It is an environmental awareness day run by the United Nations (UN). Of course, the 2030 Sustainable Development Agenda, also run by the UN, now dominates our discussions of sustainability in global affairs. However, localized visions of sustainable development continue to thrive. These development models are based on local movements that include a variety of actors with concrete grievances and focused visions for the futures of their communities. These movements and visions are relevant for World Environment Day because they reflect the spirit of this initiative through grassroots activities.
