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.
Bonded Leather is made from leather fibers that come from the stage in the tanning process where the hide is shaved to the desired thickness. It is generally not made from scraps of finished leather. The leather fibers are bonded together usually with natural latex.xplaining the difference between bonded leather and genuine leather, is the same as describing the difference between ground beef and steak.. Bonded leather, a.k.a. reconstituted leather, may contain 17 percent leather scraps, but it's still a man-made material.
