Causes of global warming

When burning fossil fuels such as coal, oil and natural gas to generate electricity or supplying electricity for automobiles, carbon dioxide contamination is released into the atmosphere.
Australians are the major producers of carbon dioxide pollution compared to the rest of the world. The per capita carbon dioxide pollution level is nearly twice the average of other developed countries, more than four times the world average.
Power generation is the main cause of carbon contamination in Australia, as 73% of our electricity comes from coal and 13% comes from the combustion of natural gas. The remaining 14% is caused by renewable energy such as hydraulic power, sunlight, wind power, and carbon contamination does not occur.
Reducing coal and natural gas production and increasing the amount of clean renewable energy such as sunlight and wind power means reducing carbon contamination. This is one of the main ways we are coping with global warming.
Plants absorb carbon dioxide from the air and release them into the atmosphere, so they play an important role in climate adjustment. Forests and bushes act as carbon sinks and are an effective means to control global warming at 5 ° C.
However, for the sale of agriculture, urban development, infrastructure development, or wood products such as wood and palm oil, humans have wiped out a wide range of vegetation around the world. When vegetation is removed or burned, the stored carbon is released into the atmosphere as carbon dioxide, causing global warming. One-fifth of global-scale greenhouse gas pollution is caused by deforestation and deforestation
Prevention of forest loss and planting by afforestation and afforestation is an important initiative to prevent global warming.
Animals, especially animals such as sheep and cows, produce methane, which is a greenhouse gas. When livestock is grazing as much as Australia, the amount of methane produced is the main cause of global warming.
Australian agriculture accounts for 16% of total greenhouse gas emissions. Using different fertilizers and different feeds will help reduce agricultural contribution to climate change.
Another reason for global warming is that the destruction of the ozone layer means that the ozone layer is falling on the South Pole. The ozone layer is decreasing by increasing the discharge of chlorofluorocarbon gas. That is the cause of human warming. Chlorofluorocarbon gases are used in industrial washing liquids and aerosol propellants in refrigerators in many places, and when they are gradually released, the ozone layer in the atmosphere declines. The ozone layer protects the surface of the earth by preventing harmful sunlight from reaching the earth. However, the progressive decline in the ozone layer is an important sign of increasing global warming on the surface of the earth. Harmful ultraviolet rays enter the biosphere, are absorbed by greenhouse gases, eventually leading to global warming. According to statistics, it is estimated that the size of the ozone hole in 2000 is twice the size of Antarctica (25 million square kilometers or more).
The cause of global warming is somewhat similar to a series of events, but you can call it a chain. The first step of global warming is to reduce the Earth's ozone layer. Then, all of the carbon dioxide is produced on the earth. As mentioned in the main reference material on global warming, "Before long, 8 billion tons of carbon dioxide entered the atmosphere." After a long way, there is methane gas. Methane gas can be generated by both people and the earth itself, both of which contribute to global warming. Of course there is a greenhouse effect
Causes of nature of global warming and causes caused by humans. Gas which is the natural cause of global warming is also known as "greenhouse gas". Although gas is one of the natural causes of global warming, humans degrade the ozone layer and increase the gas by burning fossil fuels too much. Carbon diox
