In her contribution to the CPA, Nancy Olewiler warns that Canada is facing a crisis due to the mismanagement and loss of its natural resources and habitats. She argues that in order to secure natural capital in Canada, we must put a price on the ecological goods and services that our natural environment supplies. A number of market-based mechanisms are proposed to achieve this, including a tax on carbon and air pollutants (CAP tax), the revenues of which would be used to finance a national conservation plan.
