What is Greenhouse Gas Emissions?
Greenhouse gas emissions are gases that cause the Earth’s atmosphere to become warmer, leading to global warming. These gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), fluorinated gases and water vapor. They are released into the atmosphere from a variety of sources, both natural and man-made. Natural sources of greenhouse gas emissions include volcanoes, ocean currents, plant respiration and decay processes. Man-made sources include burning fossil fuels for energy production, industrial processes, land use changes such as deforestation and agriculture, transportation activities like driving cars or flying airplanes, as well as human activities such as manufacturing goods or even breathing.The primary cause of increased levels of greenhouse gases in the atmosphere is burning fossil fuels like coal, oil and natural gas for energy production. This process releases large amounts of CO2 into the atmosphere when burned which traps heat in the Earth’s atmosphere causing global warming. Other man-made activities such as agricultural practices like tilling soil can also contribute to increased levels of greenhouse gas emissions through the release of methane from animals; fertilizer use; burning forests for land clearance; and other forms of deforestation all add additional CO2 to our air. To reduce our impact on climate change caused by these emissions it is important that we take steps to reduce our reliance on burning fossil fuels for energy production by turning to renewable energy sources such as solar power or wind power instead. We can also reduce our individual carbon footprints through limiting driving distances whenever possible; buying local products where available; eating less meat; reducing waste generation; planting trees in cities or rural areas; reducing water usage in homes and businesses; insulating buildings properly so they use less energy for heating/cooling purposes etc.. All these actions can help us collectively have a positive effect on reducing global warming by decreasing overall greenhouse gas emissions into the atmosphere.
