Biodiversity

Biodiversity is a term used to describe all the living things that make up the web of life on Earth.

From a microscopic bacteria to a polar bear!

From a gum tree to a blow fly!

Activity: What would life be like without all these strange animals?

Habitats

A habitat is the place where an organism lives.

A habitat will provide the animal with the resources it needs for survival.

We can show how organisms connect through food chains and food webs…..

Why do we need biodiversity?

We need high levels of biodiversity for clean air, food, fresh water, clothes, energy and medicine.

Without biodiversity, life for humans would be both dull and dangerous!

Threats to Biodiversity

Humans have been damaging our biosphere and ecosystems, which is affecting our biodiversity!

What has happened in these pictures below?

Although humans have been changing the Australian landscape for 50,000 years or more, the changes in the last 200 years have caused a terrible loss of soil, vegetation and biodiversity.

This sounds bad! What on earth are we humans doing to cause all this?

What are humans doing…

• Pollution • Deforestation

• Introduced Animals

• Climate change

Tips for helping biodiversity

• Use less stuff!• Plant native plants in your garden - good for the birds, butterflies

and bees, and good for the soil!• Pollute less by driving less, buying less and wasting less and

thinking about what you’re flushing down the drain!• Buy organic fruit and veggies if you can - these haven’t been

sprayed with chemicals that can harm biodiversity!• Lock up your pets at night - the night belongs to native animals!• Donate some time to vegetating or cleaning up a local wildlife

park!• Choose sustainably harvested fish to have with your chips!• Spread the word!• For more tips and more information on biodiversity visit the Cool
