Global warming means the increase of the earth's temperature by a few degrees because of the increase in the volume of water, which contributes to a sea-level rise and the emission of gases that trap the sun's heat in the Earth's atmosphere, such as carbon dioxide, methane, and nitrogen. It's also caused by the burning of fossil fuels like gas, oil and carbon and industrial pollutants. All these gases and oil is a result of the progress in the industrial world when we use oil and gas to get electrical because we get also bad gases like carbon dioxide, methane, and nitrogen, which rise cause an increase in toxins and heats air.
After we know the causes, we should take action to reduce greenhouse gas emissions, so we try to be cleaner and use less fuel and cleaner energy such as solar energy, wind power and tidal energy which converts the energy of tides into electricity or other useful forms of power.
