Thomas Eisner once said, “Biodiversity is the greatest treasure we have… its dimishment is to be prevented at all cost” (“Quotes From Prominent”). Biodiversity is the variety of life on Earth, and the importance of maintaining it is not well known throughout the world. As humans continue to take over the planet they are affecting the surrounding environment. When people drive one species to extinction, it will upset the balance in its own ecosystem. For example, without the prey in a specific ecosystem, the predator would be left with less food to eat. There are 20 species of plants, such as wheat and corn, which provide 90% of the world's food (“Why Save”). Animals and plants provide people with food and medicine, and taking those …show more content…
Ninety-one out of the 103 known lemur species are threatened. Plants such as the drawf lake iris, eastern prairie fringed orchid, and fassett's locoweed have all become threatened by habitat loss (“Most Threatened Species”). Due to pollution, America's national bird, the bald eagle, nearly became extinct. Before the discovery was made by scientists, the synthetic chemical DDT released by humans was causing reproductive failures in bald eagles (“Wildlife and Pollution”). If scientists had not come to this realization, the eagles could have been gone forever. Along with habitat destruction, the fashion industry is a major threat to animals. Many animals are slaughtered for their fur or skin in order for the material to be transformed into clothing. About 85% of this hunt for animal skins comes from fur factory farms. Fur farmers use the cheapest killing methods possible, such as suffocation, electrocution, gas, and poison. Animals threatened by fur farms are foxes, rabbits, and spotted cats (“Fur Farms”). Wool is another item that promotes animal cruelty in order to make money and clothing. The wool comes from sheep that are often skinned and killed instead of simply sheared (“The Wool Industry”). If humans continue such unnecessary acts against sheep, they could become endangered. Next is the leather industry, which threatens cows, pigs, goats, and sheep. Along with killing animals, this industry also damages the environment.
