Australia's Unique Nature and Environmental Challenges

I chose the topic Australia’s nature because of the high biodiversity and the beautiful nature. A lot of animals that lives in Australia is only native to Australia. I also chose the topic because of my love for science and the biology part of the ecosystems we see in Australia. It’s also important to look at the problems that threaten Australia’s environment.

What is Australia’s nature?

Climatic and geologic events helped australia to form its unique fauna. Australia was a part of Gondwana (The huge super-continent of the southern hemisphere) And about 50 million years ago australia became an island. Due to this isolation and lack of predators, australia developed its distinctive nature.

Australia’s landscape is incredibly diverse. They include a wide variety of habitats for its wildlife, including tropical rainforests, deserts, rivers, mountain ranges and marine environments. But its not only the wildlife that are exhilarating, but also the flora and fauna. More than 80 percent of Australia’s flowering plants, mammals, reptiles and frogs, are unique to the country.

Problems

Australia has had a variable and mostly arid climate as long as humans have been on the continent. Observations have shown increases in warmth and rainfall increases in many tropical areas and rainfall decreases in many temperate areas. Impacts will be geographically variable but mostly negative for biodiversity, agriculture, and infrastructure. Extreme events such as bushfires and floods will increase in frequency and intensity, concentrated in summer. With an economy heavily dependent on coal for domestic electricity generation and as an export commodity, Australians are high per capita contributors to anthropogenic climate change.
