The Ecosystem In The Fox's Cycle

As biodiversity declines, the causes have become evident: habitat destruction, pollution and overexploitation. Humans have had a huge role in the decline in biodiversity, and a perfect example is coral reefs who fell victim to overharvesting, pollution, and global warming. With the coral reef being home to one-third of fish species, humans have severely impacted the fish species by destroying their homes. Overexploitation is a huge risk, and this became very evident when the wolf population in Yellowstone was wiped out. Every wolf was hunted and killed in Yellowstone, and once the wolves were gone, the ecosystem became very unbalanced and many species started to either die out or be overpopulated. As for methods to help sustain species, core reserves and wildlife corridors are very effective methods. Core reserves are natural areas for organisms away from human influences. Wildlife corridors are areas of protected and combined core reserves that enable the organisms to be more free and safe between habitats, without the isolation of core
In the mid-1900s, the Channel Island Fox population crashed drastically resulting in many negative outcomes: “most bald eagles were wiped out, skunks and non-native weeds increased, golden eagles colonized the land and ate piglets and foxes, and deer mouse population rose,” (Audesirk 524). The biodiversity became unbalanced due to drastic changes in species population numbers. “The Wolves of Yellowstone”, as previously mentioned, is an eye-opening essay about when the wolf population was completely wiped out from Yellowstone, and the ecosystem there was deeply challenged because of the absence of their keystone species. In Yellowstone, no wolves meant no elk, which lead to all of the vegetation being over grazed from the elk. “Foods of the Gods” is an essay written about cacao, which is
