What are the pros and cons of extending the human lifespan?

Cons

The world is already terribly over-populated and is rapidly becoming even more over-populated. Extending the lifespan will mean more crowding, more mouths to feed, more environmental degradation, and more resource depletion. Malthusian dynamics ensure that providing a longer life for some must be purchased at the high cost of a more brutal life for the many- a life threatened by even more wars, migrations, famines, and epidemics.

Only the rich will be able to afford new products that prevent aging and promote longevity. The resulting caste system based on lifespan will be even more unfair than our current divisions based on wealth and power.

pros

Overpopulation is best solved by reducing birthrates. This has already been done with great success almost everywhere in the world except Africa and the Middle East. It will be a better, more mature, and healthier world if people live longer and have fewer diseases and fewer children. A longer lifespan will make people wiser, more future oriented, and less willing to take foolish risks in the present. This could lead to more rational decisions on how best to preserve our planet as a decent place to live.
