Since the mid-1900s, humans have been exerting an ever-increasing impact on the global nitrogen cycle. Human activities, such as making fertilizers and burning fossil fuels, have significantly altered the amount of fixed nitrogen in the Earth's ecosystems. In fact, some predict that by 2030, the amount of nitrogen fixed by human activities will exceed that fixed by microbial processes (Vitousek 1997).
1 Faux leather is man made fabric (usually polyester) that has been treated with wax, dye, polyurethane, or PVC (polyvinyl chloride) for color and texture that feel like real leather at a much lower cost.
Bicast leather is: A split leather with a polymer coating. The polymer coating is created as a separate layer and then applied with adhesives, rather than being applied by spraying several thin coats as in ordinary leather. This results in a very even finish on a leather of generally poor quality. The thickness of the polymer layer will determine whether it can be sold as leather or re-categorised as leather laminate. Generally speaking if bicast is looked after it is hard wearing. and can be very serviceable.
