leather comes from the youngest animals, sometimes unborn ones taken
from their dead mother's womb. So don't be under any illusions about
leather being an innocent by-product of meat production. Tanning animal
hides into leather is also polluting: tanning, dyeing and finishing
use poisons such as chromium, which pollutes waterways and is known
to cause cancer. 2, 14

Technology states, "On the basis of quantity of energy consumed per
unit of product produced, the leather-manufacturing industry would
be categorized with the aluminum, paper, steel, cement, and petroleum
manufacturing industries as a gross consumer of energy." Leather products
are not easily biodegradable, because the primary function of a tanning
is to stabilize the collagen so that they are not.
