Abstract
The problems caused by new biological organisms in Ogasawara Island of Japan include : (1) loss of native species' habitats and extinction of native species due to the multiplication of invasive species; (2) reduction of native species and confusion in the food chain in result of invasive species' predation; (3) confusion in genes due to hybridization of new and native plants; and (4) destruction of ecosystem and erosion of earth due to rapid increase of invasive species. The natural ecosystem of preserved areas in Korea is constantly confused and destroyed by new animals and plants, but Korea does not has any solutions because new animals and plants rarely affect human lives. Invasive species are manually introduced by humans and are considered disasters caused by humans. Korea is in desperate need of campaigns as the general public does not understand the seriousness of the destruction and confusion of natural ecosystem caused by new biological organisms and their indirect/direct influences on humans. It is necessary to evaluate the biological characteristics, ecological influence, and harms of invasive species in preserved areas to establish a system to manage invasive species and plan the priority removal of species that are highly harmful and locally distributed. Manual removal and suppression of new biological organisms that cause problems is effective, but it takes cost, effort, and time. Therefore, we would need to research and develop the most efficient and effective techniques and measures to manage invasive species in our ecosystem.
