9. Scientists have found a strong additive to feed that may block or cut back methane from cows. What’s it?

Reply: D. When fed to cows, a selected type of seaweed, asparagopsis, accommodates a compound that blocks the enzyme that produces methane throughout the digestive course of. As a lot as 98 p.c of methane is prevented from forming, scientists say.

10. What affect does this additive have on dairy or beef merchandise?

Reply: D. Farmers say that adding small amounts of asparagopsis to animal feed doesn’t have an effect on the style, texture or high quality of dairy or beef merchandise.
