Collision of two different ideas of the future
On one hand, you have immortality is within our grasp by 2050 and on the other, you have this link extrapolates the end of the oil-guzzling-dependent civilization as we know it sometime in the near future (< 2050?). Jeez, this is inspiring and depressing but mostly depressing.

CAVEAT: I haven't really done any further fact-check/research on the data behind these sites.
