Non inbred Invasive Plants - The Invasion of America by the colour StarthistleIntroduction Our planet is made up of seven continents and seven oceans place hundreds of thousands of environments and eco dusts, each with unique variations, compositions, and distinctions, and each c arfully balanced in the functions of its varied members. Over time, equilibria have been reached, as the organisms that populate scopes stabilized, intermingled, and interacted with weather, soil, water availability, and other countless environmental factors. This is not to say that such environments are stagnant, for they are furthest from it. In order to remain healthy and profitable, however, change must reach slowly in an ecosystem, so that all members of the ecological community squeeze out adapt and survive. Radical change results in unplayful instability and threatens the livability of the system for the animals, plants, and even humans who depend upon it. As systems are vas tly divergent and extremely delicate, species that are successful, profitable and enhance the livability in one area are sometimes entirely inapplicable and in fact dangerous in another. It is for this reason that we find ourselves confronted, in recent history, with a comparatively new problem nonnative species invasion. As human populations have begun to put away in widespread travel, exchanges, and modification attempts worldwide, they have also--both knowingly and unknowingly--introduced, transported, and intermingled species between ecosystems in a manner that is neither gradual nor delicate. Imbalances and frailties have ensued in the really ecosystems upon which we depend for our survival, health, and economic success. New animals, plants, bacteria, and organisms of all shapes and sizes and from every kingdom are being introduced to once stable environments on a regular origination through human carelessness and ignorance. Once introduced, they often negative ly need their newfound homes, taking over with unexpected force and threatening the native organisms. Many are well known, like Kudzu, an oriental plant initially introduced for erosion control, which now covers millions of acres in the Southern United States, or the tiny Zebra Mussel, originally found in Poland, which now blocks water provide and treatment systems nationwide. Invasive species are not a distant threat which will make their effects felt twenty or 30 years from now. They compose a current problem having major impacts on life and industry everywhere, and the magnitude of this problem continues to grow.
