That's being done in certain communities across Canada. It's in certain locations, but it's not the norm.
When you're talking about such things as greenhouses, technologies and others, there are certain requirements that would be affected by that. If you're dependent on diesel generation, then there are certain limitations on that or on the technology itself.
With that being said, a lot of communities are actually instituting what are now community gardens. Even myself, growing up as a young kid, our country foods actually supported us quite extensively, and so did gardens. It's slowly starting to return to that. If you look at that, it's probably about 30 years since those were the norm. Now it's slowly trying to go back there. It's going to take a while.
Keep in mind that we have global warming, which is probably going to exist for anywhere from 50 to 100 years.
