Humans will eventually perish without
biodiversity. According to the Convention on Biological Diversity (CBD) the definition of biodiversity includes
diversity at the gene, species and ecosystem levels; the types of species; and the habitats and ecosystems within
which they live. This includes the terrestrial rainforests, the freshwater lakes, the river systems, the coral reefs and
the marine ecosystems. The healthy ecosystems provide food, clean air and water for humans to consume and
survive.
