Dr. David Suzuki

The Hon. Rachel Notley
Combating Climate Change while Protecting Jobs: A Case Study of Alberta
While Alberta relies heavily on the extraction and sale of non-renewable resources, as its premiere, the Honourable Rachel Notley still managed to introduce policies that secured the biggest reduction in carbon emissions anywhere in Canada.

Simon Jackson
Nature Labs: Environmental Literacy
From climate change to the biodiversity crisis, the environmental discourse is polarized and overly simplistic, with too little effort being made to tackle the root problem — a society that lacks an understanding of nature.
