Food for the living. All life forms have the most amazing means of adsorbing sustenance, taking in good & rejecting bad. We progress. Extinction of life bah.
A few reject the statement of global warming but, other things equal, a little more warmth will surely increase cultured food, more food both to eat at home & export to other parts of earth planet. Canada would shine on.
Other things are not equal though & on the contrary are complex. Earthly effect is not limited to Canada as Canada is part of Earth planet. A largish part but still a part. Not to worry as linked earthplanet.ca (press) contains a section (regularly updated) on the physical condition of earth & forecasts will then be made here.
