| Biodiversity Biodiversity is simply the variety of all life, the different plants, animals, micro-organisms, their genes, and the ecosystems they form. Loss of biodiversity is one of Australia’s most serious environmental problems, with severe losses occurring in agricultural areas. Agriculture Agriculture depends on healthy ecosystems to provide services that include nutrient and waste recycling, pollination from insects, sediment control, and clean water. Clearing of native vegetation, some grazing practices and inappropriate fertiliser use have contributed to a decline in water quality, ecosystem function and in biodiversity. | ![]() |
