My personal perspective growing up in Sweden is basically that there are thousands of trees per capita and the tragedy is that forests are slowly taking over old farmland. In the northern half of the country you can’t grow wheat due to the short season. It’s wildly different from the more densely populated parts of Europe, but in Russia and Canada there are probably tons of similar areas with spruce and pine forests the size of small countries have always grown, and where the climate is perfect for forests and bad for food crops. I don’t think there is ever a demand for forest byproducts where it would be profitable to grow trees where corn or wheat could be grown instead.
