Meanwhile, much of the Canadian forestry
industry is doing the opposite, spraying thousands of hectares of
public forest with #glyphosate each year to promote profitable coniferous
growth, and eliminate hardwood species like aspen and birch.

The
primary ingredient in the Monsanto-made herbicide #Roundup, glyphosate
has been under scrutiny in both agriculture and forestry for years. It
remains widely used, because while softwood species like pine and spruce
can tolerate a certain dosage of the chemical, glyphosate can be
effective in eliminating the growth of hardwood trees for decades.
