If it's done right, so that you're actually regrowing forest, and you maintain the soils, so that the trees can get hold and regrow, yes. There's that period of very expansive growth that just absorbs a lot of carbon dioxide out of the atmosphere. Maintaining the soil, is critical and good forestry always takes care when roads are built s, skid roads, haul roads, to minimize the damage to the soil, and you want as little area put into road as possible in good forestry practices. That leaves the soil intact, which again is your main filter for water, that ends up in streams. And immediately around streams, you want to leave trees, because they shade the water, especially here in West Virginia is fairly unique in the East. In that we still have native trout streams. Trout are extremely sensitive to temperature. And if you were to remove the trees from right around the streams. Water temperature go up. The trout population would very quickly die. The warming that's been going on, for some time now is affecting species. Especially in the west it's showing up. You have beetle outbreaks that's killing lodge pole pine I believe it is. And what is going to replace that. Maybe something that's less usable than the Lodgepole Pine. Wether that's going to show up here in the east, effecting species, is something that has yet to be seen. Here in the east is considerably different from Out West. Out West, you'll have fairly expansive stands of mostly the same species. And they do extensive clear cutting in that area. Which, if done right, in my opinion. Is a valid management. Tool in forestry. Here in the East you have a huge mix of everything. Here we have hemlock, birch, red oak, maple and clear cutting is not as common a tool, because the markets are different. So, it is all based on the product, other than as a fuel, there would be no real reason to cut down trees. Except that now in the modern world, we have products that are made from wood, and it is the value of those products that drive what is cut from the forest. Why would we leave some things and in the ease here, one of the things that is commonly used is shelter wood cutting, where you leave big trees, remove the under growth, the big trees that you leave hopefully have good form, they look good, they're healthy trees. They will seed in the next generation of trees, and in that way, you're maintaining the soil, which is critical, which in turn filters water, and also sets the stage for future use of wood. You have product there 100 years from now. So, as a trade off, let's say between the energy in wood, and the energy in diesel, you've got a hundred and some pounds of wood as compared to six gallons of diesel. So you can, research that or you can just imagine that a 106 pounds of wood, how hard it would to handle that, to six gallons of diesel, which is already with re informs, so you can put it in to a gas tank, and obviously we've had, internal combustion engines, which can convert that diesel. To energy and you drive away. One of the things I would hope that you take away from this course, is a little bit of critical thinking which is in short supply worldwide, I think these days, especially as far as resources go. Everything is a trade off. And if we talk about construction material, wood versus concrete versus steel, concrete obviously is very special product. You can't use concrete by itself for things that require, a lot of bending strength like wood and steel have bending strength. But to produce those products, concrete, steel, or wood, wood clearly produces the least amount of pollution. Whether that's air pollution or water pollution as stated previously. Wood actually stores carbon when it's in use. Trees, absorb carbon when they're growing. One of the current big uses for wood, woody material. Plant material, is for fuel to substitute for gasoline and coal. And again, back to the idea of trade offs. One of the reasons, perhaps the biggest reason why say, gasoline Is used so widely, is you have a massive amount of energy in a very small, think of the size of a gallon. The amount of energy in that gallon of gasoline, to be matched by say, the volume of wood, you would need a huge amount of wood to produce that same amount of energy. So again, the trade offs.
