It&#x27;s interesting that very effective technical solutions exist to the global warming. Yet, we are rejecting for political reasons the regulatory solutions that would see them deployed on an industrial scale.<p>A 10% levy on beef produced with strong methanogensis would make producers scramble for solutions such as these, while having an almost negligible effect on consumer prices - if sufficient time is allowed before the tax comes into effect. The results, absolutely massive, displacing trillions of equivalent investments in energy generation and transportation.

I was going to patent this idea but it’s so simple I think I’ll let you guys have it.<p>Did you know methane is lighter than air and rises? So we simply house cows in a building where the ceiling is a conical shape and we periodically collect the methane from the top.<p>Or if it’s too hard to collect we simply pass it through a flame as it leaves the top of the cone and convert it to co2, way less of a warming gas compared to methane.<p>I suggest this under the assumption most cattle are factory farmed meaning raised indoors? But you could arrange for them to at least be in this building during peak methane production. Timing their food intake and such.

Carbon emissions from cows are made up of carbon from the current environment. Not fossilized carbon. Even as methane, it&#x27;s not a big deal, it&#x27;s short-lived, and ultimately carbon-neutral.

Or we could re-evaluate how we eat and drastically reduce the amount of meat produced and consumed.

So instead of taxing carbons... just mandate that cows have to eat these
