Key Points. The biosphere comprises of a complex collections of innumerable organisms, known as the Biodiversity, which constitute the vital life support for survival of human race. Biodiversity is being lost at rates that far exceed any in recent geological history. Rise in population growth levels has proven to be a problem in our ecosystem. The introduction of invasive species can cause serious problems to the natural local ecosystems since they can carry diseases that may harm local species. But their end was due to the process of natural development in which more successful species replaced the less successful species. Although biodiversity covers variability in natural systems at all levels, from the genetic, through organismal to ecosystem, biodiversity loss metrics are most often expressed at the organismal level, e.g. When extinction occurs it is normally irrevocable and the particular species disappear for ever meaning that some biological aspect of the Earth is lost. The loss of biodiversity has always been a nature’s part of evolution.

This be easily understood by observing detrimental effects of global warming and acid rain which cause an unfavorable alteration in logical processes. Promoting a natural environment with an abundance of species may be beneficial in improving human physical and mental health. Biodiversity is the variety of species present in the biosphere; the main goal of conservationists is to preserve biodiversity. Biodiversity is defined by International Convention on Biological Diversity as “the variability among living organisms for all sources, including terrestrial, marine, and other aquatic ecosystems, and the ecological complexes of which they are part”(Baumgartner, 2001).
