Assessment of life on Earth reveals humanity’s disproportionate impact

That title distills a reasonably non-contradictory article down into something nonsensical. Oddly, the URL seems to be coherent and reflective of the article.<p>&quot;human-race-just-001-of-all-life-but-has-destroyed-over-80-of-wild-mammals-study&quot;<p>This suggests the title &quot;Human race just 0.01% of all life but has destroyed over 80% of wild mammals&quot; might be a better one.

The article doesn&#x27;t make it clear whether it&#x27;s 83% of biomass that went extinct, 83% of individual animals, or 73% of species.

&gt;Of all the mammals on Earth, 96% are livestock and humans, only 4% are wild mammals &gt;70% of birds are chickens and other poultry<p>The articles fails to mention the obvious fact that these ratios are shifted because we breed more livestock animals, not because we kill wild ones.<p>&gt;All life on Earth is made up of 82% plants and found in 86% on land 1% in the oceans<p>Which is also a completely wrong statement. Anyone with a highschool diploma knows that the ocean contains a huge amount of biomass, probably larger than all terrestrial life combined.<p>The article seems to be taking the position that we should only have an effect on the environment proportional to our biomass ratio with other mammals. I don&#x27;t understand this idea. Are they saying more humans should die, or that more animals should die? What kind of ratio are they optimizing for?
