There is much complaining about forest fire smoke coming from Canada to the US. Smoke is one thing that causes poor air quality. There are many conditions humans have that are made worse with poor air quality. I sympathize with these people.
However , this is a bit of a rant. It bothers me greatly when complaints are made that
Canada isn't doing enough to control forest fires. In particular , le plus grand orange's comments bother me.
What is burning in Canada is the boreal forest The boreal forest stretches right across the whole country. There are no breaks . Good luck in fighting fires in the boreal forest. However, we make a huge effort. Just think of the size of this forest. Why is the smoke worse now? Just think climate change. When I was a child in the 40' s, we had far fewer fires. I rarely remember smoke.
We have had smoke here but the air quality has not been terrible. I do not look at air quality numbers
There are forests in the US but they are fragmented. The growth is different and the plants do not burn as easily as in a boreal forest.
The boreal forest burns very easily as the needles are dry.
When I start a camp fire I use paper. Aboriginals use dead spruce branches with the red needles. They call it gas. It blazes up very rapidly.
