This document discusses biodiversity and its conservation. It defines biodiversity as the variety of life on Earth, which is the result of evolution and shaped by natural processes and human influence. Biodiversity includes genetic diversity within species, between species, and across ecosystems. The challenges to biodiversity include habitat loss, overexploitation, and pollution and climate change caused by human activities. Conserving biodiversity is important as it provides essential goods and services that sustain human lives, such as food, shelter, climate stabilization, and cultural benefits. Efforts to conserve biodiversity include using and exchanging conservation techniques between organizations, education and training programs, and global targets like reducing biodiversity loss by 2010.

Biodiversity: Sps. Diversity
THE CHALLENGES FACING BIODIVERSITY. Species have been disappearing at up to 1000 times the natural rate An estimate 34,000 plant and 5,200 animal species face extinction 20% of known bird species have already disappeared 41% of mammals are in decline and 28% are under direct threat 45% of the Earth's original forests are gone. Forest areas are being lost every year. CBD 2010 Report Human activities are creating the greatest wave of extinction since the natural disaster that wiped out the many species.
