Biodiversity is stand for the variety of life at all levels of biological organization. It includes diversity with species, ecosystem and variability among living organisms from all sources. According to ‘the strategic plan on biodiversity 2011-2020’, Biodiversity is living in harmony with nature that biodiversity is valued, conserved, restored and wisely used, maintaining ecosystem services, sustaining a healthy planet and delivering beneficial essential for all people.
Not only biodiversity is so important, but also it affect three types of process involve the living world in ecosystem that is ecosystem biodiversity, species biodiversity and genetic biodiversity.
Firstly, for ecosystem biodiversity, biodiversity act as a global role in

Recent changes in climate have already had significant impacts on biodiversity and ecosystems in certain regions. As climate change will become more severe, the harmful impacts on ecosystem services are expected to outweigh possible benefits, such as a longer growing season, in most regions of the world. Climate change is expected to exacerbate risks of extinctions, floods, droughts, population declines, and disease outbreaks.
Many drivers affecting biodiversity are stronger today than they were in the past and are also occurring together. Because exposure to one threat often makes a species more susceptible to another, multiple threats may have unexpectedly dramatic impacts on biodiversity. Drivers of extinction range from local to global in scope and from immediate to long-term in their effects. For example, the extinction of species due to habitat loss can be rapid for some species, while it may take hundreds of years for others. These are the reason that makes biodiversity so important.
