The Act #ForNature Global Online Forum took place on 7-10 June 2020. This forum brought together citizens, government and non-governmental organizations, businesses and scientific institutions from around the globe to engage in a series of open and inclusive discussions across a diverse range of topics from healthy ecosystems and marine plastics to global food systems, youth and more. This forum was built on the momentum created by World Environment Day on 5 June–a day that recognizes global change requires a global community; inspires positive change; and calls for collective, worldwide environmental action. The forum paved way for a successful United Nations Environment Assembly-5, by building a compelling case for transformational change for nature and people in the context of the post COVID-19 world.
