<p>[QUOTE=&quot;medoraman, post: 1840745, member: 26302&quot;]There is the rub in some respects. In what way are they &quot;finite&quot;? Theoretically or economically? Theoretically yes this number is fixed, yet we to this day do not know what it is on planet earth. Economically recoverable reserves is changing every day. Loook at aluminum. Its one of the most common metals on earth, yet until the 1880s was one of the most expensive because ECONOMICALLY we could not recover it from the ore. Then we developed a new procedure and now wrap fish in it. </p><p><br /></p><p>I just read an article a couple of weks ago about nickel, and how the price of nickel got destroyed because the Chinese discovered a way to use pig nickel instead of high grade product, and demand for high grade nickel took a major hit. The same article, (in the WSJ), talked about all kinds of new methods of recovery for all kinds of minerals, and how the economically recoverable quantities keep growing despite BRIC countries because of technology.</p><p><br /></p><p>I am just saying its not a simplistic argument. The reserves are not a static thing like a gas tank, with every mile you drive leaving you with less and less gas. With commodities sometimes you drive 300 miles and end up with 5 times more gas than when you started. This was the fallacy of peak gas and peak oil arguments. They NEVER assume technology will open up new reserves for use. They always start with economical reserves today and draw it down. History shows us repeatedly that humans will find a way to expand our economically proven reserves with technology.[/QUOTE]</p><p><br /></p>
