After approximately 3.5 billion years of evolution, a disappearance of it all is vastly approaching. The Earth has seen such a catastrophic event before, mass extinction. In fact in the last approximate 540 million years; the Earth has seen five major mass extinctions (Anthony D. Barnosky, et al 51). These occurrences are so memorable that they are known as the "Big Five  (Anthony D. Barnosky, et al 51). However, this epoch, the Holocene Epoch, may soon be known as the Earth's "sixth mass extinction.  The Holocene extinction is underway and it is said that it will be like no other mass extinction before. Unlike, all the previous extinctions that have been driven by natural environmental transformations or tragic asteroid strikes, the Holocene extinction will be associated to loss of biodiversity due to human activity (Carey). Whether one believes that we are facing a mass extinction in this epoch or not, the fact that Earth is losing biodiversity is undisputable. Since around 1500, more than 320 terrestrial vertebrates have become defunct (Carey). Studies suggest that the remaining terrestrial vertebrate populations that survived the extinctions have shown a twenty-five percent average decline in abundance (Carey). All of these statistics and decline are linked to humans. Earth's biodiversity consists of all the variety of plants, animals, and other living things in the world. Everything that lives in the Earth's biodiversity is part of the web of life. From every species of vegetation and every creature on Earth, each have a place and plays a vital role in the circle of life. Plants, animals, and insects all interact and depend upon one another for what each offers, such as food, shelter, oxygen, and soil enrichment. However, humans are co-opting resources, fragmenting habitats, introducing non-native species, spreading pathogens, killing species directly, and changing global climate (Anthony D. Barnosky, et al 51). All of these things, to include many more, are now causing the sixth mass extinction through humans' infringement on the Earth's biodiversity. The biggest influence on Earth's continuing loss of biodiversity is overpopulation. Currently, there are more than seven billion people on Earth, and approximate
