The cyanobacteria changed the composition of the earth’s atmosphere by evolving oxygen in what is referred to as the Great Oxygenation Event. This also allowed the ozone to be formed and block off most of the UV rays that are destructive to genetic material. Life was, therefore, also able to exist on land other than in water.

Due to its cleaner combustion, natural gas is the most environmentally safe fossil fuel. Natural gas doesn't have as many toxic combustion byproducts as other fossil fuels.
- Natural gas is adaptable. Starting and stopping a gas-fired power plant is substantially faster than one that burns coal.
- Due to its flexibility, it complements renewable energy sources like solar and wind, which are only usable when the sun is out and the wind is blowing.
- When burned to produce power, natural gas is the cleanest-burning hydrocarbon, releasing about half as much carbon dioxide (CO2) and only one-tenth as much air pollutants as coal.
- By switching to natural gas from coal, there is a significant opportunity to cut CO2 emissions and air pollution in the near future.
- Because Natural gas is now so widely accessible through LNG, it can assist nations in coping with short-term supply interruptions.
