The article gives only the most passing nod towards cremation: is cremation a more environmentally sound option? How are cadavers donated to science disposed of?

There a more environmentally sound form of disposing of bodies called alkaline hydrolysis [1]

The environmental benefits of alkaline hydrolysis are significant. Its carbon footprint is about a tenth of that caused by burning bodies. Mr. Wilson said liquefaction uses a fraction of the energy of a standard cremator and releases no fumes.

I wonder what would be the downside of dumping them in the ocean or deep bodies of water and letting the fish go at them.

The same as described in the article, you’re just shifting it from land to sea.

In Leuven in Belgium the Vesalius Institute administers this. The remains are normally buried in a part of the municipal cemetery called the 'Anatomy Field'. There's small gravestones with the names. I think it's kind of nice.

You can, however, arrange cremation or burial wherever you please.

That would be hard to measure, but I'm sure if we all started cremating our dead the environmental cost would go up significantly. I found a list [1] of cremation rate by country. For quite a few countries, the majority of people cremate their dead (religious reasons, usually), but there's still a minority elsewhere.

I think the freezing and shaking method sounds pretty good in terms of environmental cost.

Why would the environmental cost of cremation be higher than of burying? The required land for a cemetery alone has a huge environmental cost.

I said it was hard to measure, not that the cost is greater. I don't know if it is or isn't.

Freeze dried? I'd be glad to have an instant version of myself- two teaspoons in hot water, stir, and you can chat with your dead uncle for an hour or so. That is, until the jar is empty.

In the UK, by incineration.

One of the cooler things to do with your corpse I ran across over the years is to end up at a body farm [1]. Helps the CSI types learn new forensics science!
