I have no issues with them working with the bacteria inside cows guts to help reduce the CO2 that they pump out.
But expect this to be swept under the rug by the radical enviro-left because it is not that they want low emission cows, they want NO emission from No cows at all.
Because the believe in this ideology:
Giving society cheap, abundant energy would be the equivalent of giving an idiot child a machine gun. Prof Paul Ehrlich
I sure do!
Cows don't MAKE carbon. They don't eat fossil fuels. They eat plant matter that uses atmospheric Carbon (CO_2) to grow. One cow, a million cows, it makes no difference because the carbon budget is a wash.
Now there idiots want to mess with cows' innards. They just want control of your food.
