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.
The definition of homology is the existence of shared ancestry between a pair of structures, or genes. DNA contains the genes of a person therefore making itself a homology.
I hope this helped you hon :)
Normal cells may undergo changes during cell processes that can lead to cancer. However, most of them do not form cancer because DNA repair system fix mutation before it causes cancer.
Explanation:
The major checkpoints in the cell cycle are G1, S and G2 phase. During the S and G1 phase of interphase base excision repair system is most active and prevent passing of errors in the daughter cell. The daughter cells are formed in the mitosis, it is in this phase if the mutation has been in the DNA the cells would replicate abnormally.
Las actividades económicas tienen que ver con la obtención de alimentación, medicinas, madera y leña. Además de la elaboración de carbón y materiales para curtir pieles. Además de eso ha habido visitas turisticas, la pesca deportiva y la observación de aves. La verdad ha sido mas el perjuicio que el beneficio. El beneficio es completamente económico pero entre los perjuicios esta la contaminación del agua por la construcción de presas y el cambio de suelos por la contruccion de varios proyectos
