Kamala Harris recently warned about the great impact meat production has on planetary ecology and that more vegetables in the American diet would lighten such a detrimental environmental impact. Such comments are rooted in the Green New Deal that is rigged to drastically reduce livestock production. Cows in particular are singled out for all of the methane they produce that leads to a significant contribution to greenhouse gases in this country.
In 2019, Alexandria Ocasio-Cortez urged kids in a Brooklyn school to save the planet by stop eating meat. Silicon Valley has plans to replace real beef with fake meat through what they call cellular agriculture technology. While no one has demanded incentivizing or requiring a vegetarian diet yet, needless to say, beef and meat prices would skyrocket under such schemes.
