In my search to decide whether or not it's a good idea to have a kid I came across a tounge only slightly in cheek movement called VHEMT (pronounced vehement) They argue that we shouldn't have kids because it's detrimental to all of the life on the planet.

They make some good arguments. It's a little bit selfish to have a kid when there are thousands dying of hunger in other parts of the world. Not having a kid is probably the least I can do. That and sending cash to kids like the one here with skinny legs would seem like the only humane things to do. It's ironic, and I don't often use that word, that because healthy food is expensive low income people are more likely to be obese in America. ($.29 hamburger tuesdays at McDonalds) It's totally bassackwards.

The site also makes the interesting point that because we're not smart enough as a species to prevent starvation we could end the suffering simply by not having those kids in the first place.
