A con that is that eventually all of the forest will be destroyed.
Explanation:
The clearcutting method is a method that is often used around the world, so it is no wonder that this happens in Oregon as well. While the clearcutting manages to supply the market and even create surplus with timber and later its products, it also has several negatives about it. One major con about the clearcutting is that eventually all of the forest will be destroyed.
Because this method is based on mass cutting down of wood and not using any sustainable means, such as planting saplings on the places that were cut and cleared, it has terrible effects on the long run. Bit by bit, the forest will be cut in total, and because it was not renewed in meantime, the only thing that will be left behind will be barren and heavily eroded land.
This will cause big problem for the timber industry as they will have nothing to work with. The prices of the timber products will skyrocket because of this. The ecosystem will be totally destroyed. The land won't be used for agriculture because the soil is of poor quality and because of high rates of erosion.
