Reply #116: The thing is, if you have kids, you live for them.

[Bonobo]

If you have kids, one of your biggest reasons for living is to protect them and see them get bigger.

But if you do not have kids, then what is your EXCUSE for staying alive and using resources? Simply because you like being here, right?

You see my point? Ultimately, you cannot apologize for having the drive to live, can you? Neither can you be blamed for having the drive to procreate and the concurrent optimism that your kids MAY help create a better future.

The problem with the OP's original post, and with what you are saying, is that utlimately, it would dictate that all but a few should willingly commit suicide in order to save the world. It runs contrary to the nature of all life, the desire for survival.
