I would say that what's been done can't necessarily be completely redone. If you launch a national hard or green infrastructure funding program, the primary objective of such a program must be to establish goals that respect the support capacity of ecosystems. That's what is to come for future generations.
Each ecosystem has a capacity for absorption. Take the Great Lakes. I haven't stopped looking at the photo since this afternoon. The Great Lakes are dropping, the St. Lawrence River is dropping and all waterways in Canada are affected. There are a number of reasons for that. You have climate change, evaporation, vegetation being cut down along the water because we want to be close to the water—people always want to be close to the water. This has a negative effect. We want to channel more and more.
We are going to fight to reopen streams and waterways in Montreal. This is in the process of being done. They disappeared because of poor management in the past. People didn't have the knowledge. Today we do and we need to use it.
There is a way to achieve these models of sustainable development. Mr. Sopuck said it very well: there are probably too many engineers involved in the projects and not enough ecologists or sociologists. This requires multidisciplinary teams and each of them should respect each other and take into account the issues of each of discipline.
I also think that we will manage to have better development models and a better quality of life. Humans are also part of biodiversity.
