is cremation toxic?

This is an interesting article on the alleged hazards of cremation--that I take particular interest in because I am a staunch advocate of cremation as opposed to burial.

The reason is quite simple: why are we wasting space and resources on dead corpses? Yes, yes...vomit religious rhetoric all over me--it is still dead space (ouch, no pun intended). By the way, your grave will only be visited by one--two--generations more, tops. Then, you will be a lonely old decaying carcass, not even good for letting people cry on you. By then, you won't even be wasting space for a bad reason--you'll be doing it for no reason.

Back to the controversy of cremation. Allegedly, the mercury in amalgam dental fillings--an alloy of mercury with another metal such as silver, copper or tin--releases into the atmosphere upon cremation.

When a body is burned, mercury from such fillings vaporizes. Once released into the atmosphere, mercury returns to Earth in rain or snow, ending up in lakes and other bodies of water where it can lead to elevated levels of mercury in fish. In humans, mercury damages the nervous system and can harm childhood development. Power plants, especially those that burn coal, are by far the largest source of preventable mercury releases; Environmental Protection Agency regulations have been adopted to reduce those emissions.

But the EPA does not regulate crematories because they are responsible for less than 1% of mercury emissions per annum.

There are two solutions to the problem: Install a filter on the crematory's smokestack or extract teeth of the deceased before cremation.

By the way, the cremation industry claims there is no danger. Personally, I am sure burning mercury into the atmosphere is problematic, but I don't give a shit if you yank my teeth out or filter my ashes on the way out the chimney--I will be fucking dead and my last departing wish is to have the least detrimental impact possible.

Even without the preventative measures, I wonder what is worse environmentally: all the wasted resources of graveyard maintenance, or the emissions of cavities in burning corpses?
