Until you look at the article, which suggests that the high number is largely due to huge numbers of tiny krill and anchovies caught in fishing nets.
So while perhaps technically accurate... it's not like half a pig or half a chicken is being killed per person per day.
The problem is that this shouldn't be our goal. Is neither a realistic goal, neither would be necessarily a desired outcome.
Big animals have parasites also. You kill a cow and also millions of simbionts in the cow's gut but nobody cares. You make a modern soy field and kill everything. All green and all hairy and all winged things. All is killed except soy.
Is the typical new age religious nonsense that ends in a dead end. Is not possible to do anything in this planet without stepping over some creature.

Some species evolved to fix that and other not. Some are keys, sustainers or big modificators of the ecosystem, and other not.
And when a predator eats a prey, is that bred to be killed or wild?

> [[A graph in which one square equals 1,000,000 tons. Dark grey squares represent humans, light gray represent our pets and livestock, and green squares represent wild animals. The squares are arranged in a roughly round shape, with clusters for each type of animal. Animals represented: Humans, cattle, pigs, goats (39 squares), sheep, horses (29 squares), elephants (1 square). There are other small, unlabeled clusters also. It is clear that humans and our pets & livestock outweigh wild animals by at least a factor of 10. ]] {{Title text: Bacteria still outweigh us thousands to one--and that's not even counting the several pounds of them in your body.}}
