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.
Natural selection involve natural causes while artificial selection is by human breeding or human intervention.
The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.
There are cold fronts, warm fronts, stationary fronts, and occluded fronts.<span />
Deforestation would have the largest negative effect on biodiversity. This is because it destroys habitats and can kill off species.
