The world's biomass is shrinking...
.
Most other animals are fish. Mammals account for only about 8 percent of animal biomass and only about 0.03% of all biomass. However, within the realm of mammals, humans dominate. Human livestock, at 0.1 Gt C, account for 59.9% of all mammal biomass on Earth; humans themselves, at 0.06 Gt C, account for 35.9 %. All wild mammals, marine and terrestrial, account for only 4.2% of mammal biomass.
In the oceans, human fishing has depleted 85% of commercial fish stocks and 90% of “big fish” – tuna, marlin, and sharks. The global marine catch is down by 6.4% since the 1992, in spite of larger ships, larger nets, and improved technology. Oxygen-depleted ocean zones have increased by 75%. This is on top of acidification from carbon emissions which kills coral reefs that act as marine breeding grounds. The exploitation of marine mammals, including whales, has reduced marine mammals by 80%.

To slow or reverse this erosion of biodiversity, humanity must slow its harvest of the natural biosphere and cease the destruction, depletion, and conversion of wild habitats.
