But biodiversity is much more than species diversity in wild lands, and biodiversity loss is much more than species extinction. The loss of biodiversity directly influences the social life of the country possibly through influencing ecosystem functions (energy flow and biogeochemical cycle). Rise in population growth levels has proven to be a problem in our ecosystem. biodiversity It is a key instrument to promote sustainable development and tackle the global loss of biodiversity. For example, fish stocks are dwindling, forest loss is resulting in the loss of many species, land and other resources are being misused, leading to various long terms costs. The introduction of invasive species can cause serious problems to the natural local ecosystems since they can carry diseases that may harm local species. Introduction ISBN 978-1853836992.
