These amazing sessions on sustainability will be led by Ninna Martinez-Astroza, from Chile. Ninna graduated from Greystone Colleges CIV and Diploma of Marketing and Communication programs, winning an Academic Excellence Award 2 years in a row. Ninna has recently completed her studies in Permaculture, is an environmental leader with the city of Port Phillip, and has been studying practical utopias, trying to find alternatives that are fairer for the environment and for humans. Ninna dreams of edible cities, with a wellness society, with lots of greenery and biodiversity around and suburbs as the center of the community. We need to retrofit our neighborhoods and our communities, as before the ‘plastic’ era.
