Cows and...seaweed?

The discussion of how to deal with ruminant emissions is now as pervasive as the emissions themselves, it seems.

Here in NZ, we have the PGgRC, which has been set up to deal specifically with the issue. After all, something like a half of NZ's emissions are due to these gases! Gosh! And stories dealing with how to offset the emissions are all over the place.

In no particular order, some of the more recent ones:
The NZ Herald: Hungry bugs could slash animal-gas danger
The register: Bubbly-belly-bugging boffins battle bovine belch peril (possibly the best headline I've yet seen, and it sort of fits with the country responsible for more video tracking of its citizens than any other)
Sciencealert: Diet may cut cow fart emissions (perhaps the most direct headline)

The interesting thing is that this last strategy, if it works, could be perfect for New Zealand. We have access to lots and lots of seaweed, and lots and lots of cows. And while I'm fine with GM, I think Occam's Razor is a great guideline, and something like this is less likely to come with the usual hysterical press-release battles, and potentially unseen side-effects, possible with messing the bugs themselves (for example).

If anyone's really interested in the issue, I can happily supply more resources (and even a podcast)...
