British Columbia has more biodiversity than any other province or territory in Canada. It also has the highest number of endangered species, which suggests that we are sadly failing in our responsibility to protect the web of life. Biodiversity in B.C. is increasingly under pressure from human influences such as urban sprawl, deforestation, exotic species introductions, over-harvesting and pollution. The greatest threat to biodiversity in Canada is the alteration of habitat. Extinction is natural, but the current rate of species loss is far above natural levels.
