Can a vaccine for cows slash methane emissions?

[inavalan]

This isn't a joke, but to me it sounds like one:

In the world of climate change, some green enthusiasts assert that methane emissions from livestock, aka cow farts or "burps," are severely negatively impacting the planet.

The cow fart concern is so dire that some have even called for the totally eliminating meat-based diets, and transitioning to plant-based, only. But is that "solution" even workable?

While the green stewards engage in debate over plant- versus meat-based foods, a start-up funded by Bill Gates seeks to keep meats in the picture through a vaccine for cows, sheep and goats that would trigger their immune systems to eliminate their farts.

While previous studies show that the concept may be workable, studies are still needed to prove that actual application of the idea is feasible. In the meantime, other green groups are proposing that governments start taxing farmers for their animals' farts by 2025.
