Biodiversity refers to the variety of all life forms including plants, animals, microorganisms and their genes and ecosystems. It is important for human sustenance, health, well-being and enjoyment of life. However, biodiversity is threatened by habitat loss, invasive species, pollution, climate change and overconsumption. The loss of biodiversity can reduce ecosystem services and genetic diversity, compromising food security. Australia is taking steps to preserve biodiversity through programs, reserves, and acts aimed at conservation and education.

1. Biodiversity

2. Bio What? Biodiversity is the variety of all life forms: the different plants, animals and micro-organisms, their genes and the ecosystems of which they are a part.

3. Genetic diversity -the total genetic information contained in the genes of all species. Species Diversity- The variety of species, refers to the number of species and the number of individuals in a species. Ecosystem Diversity - the variety of habitats natural communities and ecological processes.

4. Importance Of biodiversity Humans are dependent on biodiversity for their sustenance, health, well-being and enjoyment of life. Food- we rely on biodiversity to provide us with a large and varied food source Health- Humanity derives many of it’s medicines from biodiversity.

5. The Value of Biodiversity Recreation- many recreation activities rely on or benefit from biodiversity Inspiration- Biodiversity as a whole inspires artists, musicians and writers. Escape- Biodiversity provides a sanctuary from the hustle and bustle of everyday life.

6. Threats to biodiversity Habitat loss and fragmentation (love tunnel) Competition from invasive species Pollution Global climate change Desertification Population growth and over consumption Unsustainable use of natural resources.

7. Consequences of loss of Biodiversity A loss of ecosystem services- Protection of water resources, nutrient storage and cycling, Pollution breakdown and absorption Loss of genetic diversity- Genetic diversity allows species to adapt to changing environmental conditions and stresses. Reduced food security.

8. Preservation of Biodiversity The National Strategy for the Conservation of Australia’s Biological Diversity Natural Heritage Trust Wild life reserves- e.g. National Parks. Flora and Fauna guarantee act Endangered species Program Quarantine Education Breeding Programs

9. What is happening to Biodiversity. In the past Australia’s Biodiversity has suffered greatly, primarily due to human misuse and abuse of the environment. Humans are now starting to realise the importance and value of biodiversity and are taking action to preserve it.
