Wow, you really do stretch as far as you can to defend. Have you ever bin in a forest? The forest floor is an eco system teaming with life, deadfall, and leaves, branches and shrubs serve as food and nutrients for bugs animals and vegitation, and endless cycle of life growth and death. Making a statement such as your of cleaning the floor of a forest just shows your ignorance as to that reality. Walk just 100 metres into a thick dense forest, now imagine cleaning debris or diseased or rotted vegitation, and walking back that 100 metres with said debris, and now imagine going 150 metres and do the same, see how assanine that is considering a forest can be thousands of acres to thousands of square miles, an impossible task that sounds not only stupid but naive.
