Biodiversity is defined as the “diversity of life on Earth.” This paper provides evidence to support the case for protecting biodiversity. Biodiversity is recognized as important but can often be overlooked or given a lesser weightage. This is partly because decision-making involves weighing costs and benefits and it is difficult to include biodiversity in this because its value is either overlooked or not understood. Therefore, valuation of diversity becomes necessary therefore to illustrate the importance of biodiversity. Valuing biodiversity requires an understanding of the range of benefits it provides. The main drivers of biodiversity loss are deforestation, desertification, overexploitation, invasive species, pollution, and climate change. Biodiversity underpins economic development, but it is threatened globally and its ability to continue to provide the goods and services that support economic growth is failing. Awareness-raising activities are diverse and often rolled up with activities that have broader objectives of personal and social involvement, public health or civic responsibility. In such circumstances, biodiversity awareness may be secondary or even incidental to other objectives. Due to industrialization pollution has become one of the greatest threats to global biodiversity. Many species cannot cope with the rapid changes in physical parameters which are occurring to our environment. The widespread introduction of exotic species by humans is a potent threat to biodiversity. The recent phenomenon of global warming is also considered to be a major threat to global biodiversity.”The loss of biological diversity is second only to nuclear warfare in its threat to human and other life on this planet”.
