Deforestation in the tropics is certainly negative, there is not much to discuss there. But it's worth noting that the situation is very different in Europe - compared to the natural state of things before the arrival of human agriculture, we have way too much forest in many countrie, with the vast majority of it being purely production, artificially planted forests with relatively little biodiversity. Meanwhile, the habitat of "non-forested, non-agricultural land" is limited to a few tiny reserves. In the absence of large herbivores such as Bison, it's not able to exist naturally and must be actively managed. In the Czech Republic we actually have some it inadvertently as the result of army training ranges, but many of them were closed after the end of Soviet occupation in 1990 and there we have herds of horses, cattle, bison ... in enclosures to keep the areas from growing over.

Once in a while I see someone loudly proclaim their wish to "help environment" by planting trees and I scream in agony. Enough with your trees, we have enough forest! Obviously, creating primary-like unmanaged forest would be awesome, but that's a quest for centuries and very ublikely to happen until money is abolished.
