The article / graph presented incorrectly labels materials that are renewable as ones that are not.
Aluminum does not stop being aluminum ... silver does not stop being silver ... for example.
Unless the material is leaving the planet out into space ... it is only a question of how easily available is it ... not a run out of it kind of thing.
For example ... Even with zero oil on the planet ... if you have enough desire , energy , and time ... you can make oil chemically from scratch ... you can mine land fills ... etc.
And we have several billion more years of the solar energy input.
Now run out at a specific Price $ point ... that is different ... but that is not actually running out ... it's just more expensive.
