The lights in the video below represent areas on our planet where there’s more than 1 million people. This display at the Museum of Victoria educates on the ecological impact of population growth on the environment and climate change.

Not represented is the sociological impact. Research shows that loss of ecological diversity is correlated with loss of linguistic diversity. As areas are deforested, mined and otherwise plundered in unsustainable ways, Indigenous groups that live in harmony with that ecosystem are pushed out into urban areas. Their culture and environmental knowledge is lost.
