Poverty Cut-offs in Canada

I am doing a paper on poverty trends in Canada. I have a question: What does the Canadian government use as a standard of measure to determine who lives below the poverty line? Thanks.

The Industrial Revolution

Revolutionary changes in human culture have greatly changed the relationship between humans and the environment. How have the Neolithic and Industrial Revolution impacted the natural environment, and what is meant by the Environmental Revolution? The recycling of elements is another vital functional process occurring in all ecosystems. Describe the biogeochemical cycles for carbon, phosphorous, and nitrogen. How have humans impacted these three cycles? The goods and services performed by natural ecosystems are essential to human survival. What is their overall value, and of what significance is it to measure this value?

Biodiversity

What is biodiversity and how are humans impacting it? Is maintaining biodiversity essential for human sustainability? What can be done to maintain today's current biodiversity levels?
