1.Burning fossil fuels When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.
Australians are big producers of CO2 pollution compared to the rest of the world. Our level of CO2 pollution per person is nearly double the average of other developed nations and more than four times the world average.
Electricity generation is the main cause of carbon pollution in Australia as 73% of our electricity comes from burning coal and 13% from burning gas. The remaining 14% comes from renewable energy sources such as hydro, solar and wind, which do not emit carbon.
Reducing the amount of electricity generated from coal and gas, and increasing the amount of electricity from clean, renewable energy sources like solar and wind, means less carbon pollution is emitted. This is one of the main ways we can address global warming. Deforestation Plants play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it. Forests and bushland act as carbon sinks and are a valuable means of keeping global warming to 1.5°C.
But humans clear vast areas of vegetation around the world for farming, urban and infrastructure development or to sell tree products such as timber and palm oil. When vegetation is removed or burnt, the stored carbon is released back into the atmosphere as CO2, contributing to global warming. Up to one-fifth of global greenhouse gas pollution comes from deforestation and forest degradation.Global warming, population growth, and natural resources for food production. PIP: Destruction of forests and the considerable burning of fossil fuels is directly causing the level of carbon dioxide and other greenhouse gases including methane, carbon monoxide, and nitrous oxide in the atmosphere to rise.

3.Replace Regular Incandescent Light bulb, Drive less or carpool Reduce, Reuse, Recycle Go sola, use less hot water and many more.
Eucalyptus trees do catch on fire easily, but to lower the fire risks, we need to stop acting so reckless with flammable things. So keep the eucalyptus trees, but stop acting so careless.
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.
is it ok if u could try and help me with my last question if so thx
An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.
