A graph published by researchers at the University of Washington shows various population growth predictions. The graph shows global human population growth from 1990 to 2100, predicted according to how fast we meet UN Sustainable Development Goals (SDGs).

The environmental impact of compostable plastics

Compostable plastics vary in their environmental footprints but some of them are significantly better than petroleum-derived plastics in key respects.
