An interesting opinion... but do the same modern backpacking and climbing practitioners, along with the LNT advocates, stop to consider the multitude of impacts caused by all the mining that is necessary to collect the raw minerals that must then be transported by newly laid asphalt and concrete roads across land to the port facilities, then by ships at sea to other port facilities, so the "ores" can be transported further onward to the smelters for processing into the desired metals such as the glorious titanium, stainless steel, and aluminum, followed by transport to the manufacturing plants to transform the basic metal forms into all the various cups, stoves, non-plastic sporks, etc, then the transportation of the finished and packaged product forms to the storage and distribution warehouses, then onward to all the store-fronts (brick-and-mortar and electronic), and finally onward into the awaiting hands of the end users, who then transport the product into the woods/brush for actual use? Don't forget about all various forms and amounts of energy production and consumption required all along the way... petroleum drilling and refining to supply the various fuels for running all the different types of mining and transport equipment and machinery, powering the engines of the ocean-crossing cargo ships, the required natural gas and electricity at the smelting facilities, the electricity production and consumption for running the cutting, stamping, machining, and finishing of the product at the manufacturing facilities, etc, etc. What about the loss of all the land area that was and is covered over by concrete and asphalt in order to construct the various production facilities themselves, and the raw materials that had to be previously mined, transported, smelted, and manufactured to produce the I-beams and girders to construct the buildings where the production activities occur? In my view, when all impacts are actually considered, it is the practitioners of the "primitive" skillsets who leave an extremely minute trace, in comparison. YMMV. I apologize for pursuing this tangential diversion, everyone... and I'm happily tracking back to our OP's topic.
