In case anyone takes that seriously: farmed animals mostly eat industrial agricultural food. And they need 10 kilo of food for every kilo of meat. So you're basically killing ten times as many farmland animals when eating meat compared to earing plants directly.
I thought they were making a joke that insects are part of the family and animalia and therefore you'd have to kill way more insects than you would traditional farm animals.
Traditional animal farms, or tradional farm animals?
The former is how we used to farm animals with lower density and free range, the latter is animals that have historically been bred and raised for meat; pigs, cows, etc.
Lower intensity agriculture is possible, but just not as consistent or price effective. You could, for example, raise pigs or chickens mostly on food scraps and have meat that requires little extra inputs, but maybe not if you need to raise thousands of them.
