Necessary for me to share this information with my audience because of the simple fact that they need to understand that there are very fragile and sacred environments in this planet that are worth fighting for. The Galapagos have been a conceptual landmark since its discovery and continues to grant us insight into concepts of evolutionary biology. The true essence of these islands lies in their biodiversity which is under threat; however, researchers believe that Galapagos is standing at cross roads and though the degradation rate is increasing, but with an in-depth understanding of the need for conservation, the biodiversity of the Islands can be restored. I want everyone to appreciate such rare beauty and protect them from further harm and help them maintain their integrity and identity without losing a single species in the process.My central idea is to show the importance of adaptation that occurs in both flora and fauna of the islands and how outside factors can affect the ecology such as geological formations or invasive species.The ecosystem of the Galapagos is among the best studied ecosystems in the world. According to some, the Galapagos Islands are among the most spectacular scientific discoveries. The place was colonized by humans only recently, thus the biodiversity of the Galapagos is still intact .The Galápagos is today one of the best-preserved oceanic archipelagos, where human impacts on many ecological processes are still relatively low (Thornton 1971).Though at present times the Islands are facing a certain extent of degradation which may be replaced via prompt action. It is indeed noticeable that the flora and fauna is impoverished and there is not much variety. The islands provide a fine example of how external factors play a role in evolution of the flora and the fauna that inhabit the Islands. The unique features of the Galapagos are a result of the following factors- geologically new, presence of active volcanoes and successful arrival and establishment of few living species.The flora of the islands closely resembles the flora of the South American mainland from where most plant is believed to have originated. At present there are 560 native plant species that thrive on the island. Out of these about 180 species are endemic. At the species level the plant endemnicity is 32% (Lawesson et al. These native species came to the islands by natural means such as- floating in the oceans, dispersal through air or by birds. These
