Wikipedia tells us that biodiversity is the variation of life forms within a given ecosystem‚ biome‚ or on the entire Earth. Interesting enough‚ my science teacher was starting on the Biodiversity chapter when I spotted this poster. We learnt about the classification of species using their common characteristics‚ but I realize that there are always exceptions. For instance‚ we know that mammals

Conservation of Biodiversity One of the most pressing environmental issues today is the conservation of biodiversity. Many factors threaten the world’s biological heritage. The challenge is for nations‚ government agencies‚ organisations and individuals to protect and enhance biological diversity‚ while continuing to meet people’s needs for natural resources.
