<P> Although some conservationist organizations argue that human activity is incompatible with a balanced ecosystem, there are numerous examples in history showing that several modern day habitats originate from human activity: some of Latin America's rain forests owe their existence to humans planting and transplanting them, while the abundance of grazing animals in the Serengeti plain of Africa is thought by some ecologists to be partly due to human - set fires that created savanna habitats . </P> <P> Possibly one of the best examples of an ecosystem fundamentally modified by human activity can be observed as a consequence of the Australian Aboriginal practice of "Fire - stick farming". The legacy of this practice over long periods has resulted in forests being converted to grasslands capable of sustaining larger populations of faunal prey, particularly in the northern and western regions of the continent . So thorough has been the effect of these deliberate regular burnings that many plant and tree species from affected regions have now completely adapted to the annual fire regime in that they require the passage of a fire before their seeds will even germinate . One school in Los Angeles states, ""We have let our kids go to the forest area of the playground . However, five years later, we found that none of the flowers were growing, the natural damp soil had been hardened, and all of the beautiful grass had been plucked,". </P> <P> Despite being discredited among ecologists, the theory is widely held to be true by the general public, with one authority calling it an "enduring myth". At least in Midwestern America, the "balance of nature" idea was shown to be widely held by both science majors and the general student population . In a study at the University of Patras, educational sciences students were asked to reason about the future of ecosystems which suffered human - driven disturbances . Subjects agreed that it was very likely for the ecosystems to fully recover their initial state, referring to either a' recovery process' which restores the initial' balance', or specific' recovery mechanisms' as an ecosystem's inherent characteristic . In a 2017 study, Ampatzidis and Ergazaki discuss the learning objectives and design criteria that a learning environment for non-biology major students should meet to support them challenge the "balance of nature" idea . </P>

Scientific development is disturbing the balance of nature
