In this video Jane Goodall is talking about Developing Nations. In supposed 1st world nations the question changes.

In supposed first world nations we live longer - but it is often at the expense of quality of life. Though I am not in a position to say, whose life is more important than anyone elses.

What it does bring up for me, are questions I ask myself about what is really important - human population explosion or space for the earth to regenerate? Is colonizing another planet going to solve our current issues or will we just take them to a new planet?

There are many intricate questions that come up for me around this.
