The 17% Nagoya objective is part of an international agreement through the United Nations program. However, I would suggest you go and consult the Environment Canada site. In 2004, the Government of Canada stated—and scientists are saying this, as well—that we need to maintain 30% of vegetation cover to conserve biodiversity. The 17% objective is a step in the right direction, but the Montreal metropolitan community ratified its metropolitan land use and development plan and is planning to have a 30% canopy by 2031. So we are talking about scientific objectives. It's serious.
Before going any further, I want to point out that I gave the clerk five copies of this document, which is only in French, unfortunately. You can read about the history of the last 20 years, from 1985 to 2005, of the loss of natural environments, the agricultural area and the correlation between the heat island, health, and so on. Everything is in that big report.
