From elephants to tigers, study reveals scale of damage to wildlife caused by transformation of wildernesses and human activity
The total weight of Earth’s wild land mammals – from elephants to bisons and from deer to tigers – is now less than 10% of the combined tonnage of men, women and children living on the planet.
The figures demonstrate starkly that humanity’s transformation of the planet’s wildernesses and natural habitats into a vast global plantation is now well under way – with devastating consequences for its wild creatures. As the study authors emphasise, the idea that Earth is a planet that still possesses great plains and jungles that are teeming with wild animals is now seriously out of kilter with reality.
The grim figures for land mammals were matched by those found in the oceans. The total mass of marine mammals was calculated to be around 40m tonnes. Fin whales have the largest total biomass with sperm whales and humpbacks coming into the second and third slots, respectively.
