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 two beneficial factors away would negatively change human lives. Instead of inducing endangerment through habitat destruction, the fashion industry, and hunting, humans need to protect threatened species because wildlife extinctions may jeopardize human survival.
Habitat loss poses the greatest threat to plants and animals, affecting about 85% of all species. The three main kinds of habitat loss are destruction, fragmentation, and degradation (“Habitat Loss”). Destruction takes place when humans bulldoze trees or fill in wetlands. Wildlife is cut up in order to make roads and human developments, which is called fragmentation. Habitats can become so degraded that they cannot support wildlife any longer, due to pollution and invasive species. If the removal of natural habitats does not slow, mass extinctions are bound to happen. The araripe manakin is a bird whose habitat has been minimized due to expansion of agriculture and recreational facilities. There are only about 779 individuals left...
