The greenhouse effect became the main problem in the world when the world began to civilize and industrialize. The greenhouse effect happened due to human greed and all the countries are starting to discover the method to solve the greenhouse effect problem in this twenty-first century. Everyone now focuses on the greenhouse effect because the greenhouse effect produces enormous damage and pollution to the natural system, humans and especially wildlife. So, this report intends to study more about the impact of greenhouse effect of climate change on wildlife in the world in one country which is Australia because climate change has become a big problem in Australia since the beginning of the twenty-first century and the Climate change not only affects natural systems but also wildlife. Wildlife is most affected in Australia. The purpose of this report is to provide us with further understanding of the impact of climate change due to the greenhouse effect, so that it can create and raise greater awareness about the greenhouse effect. In this way it can help prevent and reduce greenhouse gases to prevent harmful climate changes.2. How does the greenhouse effect affect climate change? Kenneth Hare examines the scientific evidence on the greenhouse effect and explains that global warming and increasing greenhouse gases are the main issue affecting climate change. Human activity is what causes the greenhouse effect. Natural greenhouse effect is a boon for our world and becomes probable for life on earth, but nowadays the temperature is very high and harms human, plant and animal life. For example, natural resources such as gasoline for vehicles and electricity for our necessary needs will produce more than billions of carbon into the atmosphere every year causing climate change on our earth every day. Furthermore, according to the United States (EPA) as a greenhouse gas Emissions resulting from human activities are slowly increasing, causing the world to get hotter and hotter, causing changes in the natural system such as changing the atmosphere, land and sea . These changes will separate both advantages and disadvantages on the natural system and wildlife. This is because all kinds of greenhouse gases can remain in the atmosphere for at least a hundred years, they will all release greenhouse gases, and the increase in climate warming will continue for a very long time..
